Bosch Litheon Batteries Exposed

Perhaps one of the biggest hurdles for manufacturers to overcome with cordless tools is the Bosch 2 607 336 915 drill battery itself. Sure, they must give strict attention to the efficiency of the motor. They must select a motor that can deliver more power output with less draw on the battery.

However, the battery is a very serious part of the equation. That’s why the Bosch Litheon is so popular.

Lithium batteries are known for providing higher cell-density. That means twice the power for twice the duration. You get more of everything.

Remember how big cell phones used to be? I remember the battery pack alone on one of my first Motorola phones. It was bigger than just about ANY cell phone on the market today.

Cell phone batteries are Lithium based.

Bosch GBA 36V tool batteries (lithium-ion) provide much more power than Nickel-Cadmium which means less voltage is necessary for comparable performance.

For example, the Bosch 10.8V drill/driver can do 80% of what the typical user is going to need to do. A 10.8V Litheon battery is very small, while still providing the kick and endurance needed.

A smaller battery means a lighter drill to carry around.

If you take an 18V Ni-Cad battery and a 36V Litheon battery, you’re actually going to see TWICE the power and TWICE the duration. You’ll be able to do more, and do it longer.

Another benefit of the Bosch Litheon is the lack of ‘memory effect’. Ni-Cad batteries (as well as other types) tend to develop a memory that keeps them from charging to full capacity if not fully discharged.

Lithium-ion batteries don’t have this problem.

Granted, these batteries are more expensive to manufacture (and drive the cost of tools up), however, that price is offset by performance and time lost recharging, as well as the life of the battery.

Yet another benefit of Bosch Litheon is that Lithium-ion D-70771 batteries have an extremely low self-discharge rate. Self-discharge is what occurs when you charge the battery and leave it on the shelf. Lithium-ion batteries self-discharge at around 0.1% each month, which means you’ll lose around 1% of charge over a year’s time – not much to worry about.

Building and Repairing Things Become Fun With The Right Power Tools

Let’s imagine you are about to start a huge renovation project in your apartment or a big house your family owns. Yes, you have good reasons to freak out since they say that renovation never stops once you get started. When you have a renovation project and you are given a Black & Decker A1718 battery to help you do it, you will find that work progresses a lot more quickly. Yes, tools make life easier because they ease the work man has to do with his own hands. Today, tools are a part of almost every household. Every home needs a screw to be fixed or some woodworking to be done. If you are a professional craftsman or woodworker, you will need tools even more as they are crucial to earn your living. On the one hand, one may think that purchasing and using power tolls is a breeze. Yes, there are lots of tools and gear for homeowners these days. You can buy them online and offline. There are plenty of brands, to offer decent products at low prices. Modern tools sell all over the world. Makita, Bosch, Dewalt, Hitachi etc. are renowned brands that manufacture and sell modern tools all over the world.

Gone were the days when people depended on their sheer physical strength to get manual work done. In the past, people relied on hammers, saws, grinders and wrenches to be able to do their repair or construction work. Today, these tools are still useful but one can accelerate the efficiency of their work by using what are called as “cordless power tools”. There are many advantages to cordless tools and not having to constantly untangle wires and cables is undoubtedly one of them. It also helps to flick the switch on the screwdriver knowing you don’t have to apply any brute force to get the desired results.

The following are examples of the most commonly used cordless equipment:

DeWalt cordless – DeWalt cordless tools are well known for the power they have available and for their batteries that are long lasting. The DeWalt cordless tools are ideal for those situations where electric outlet is not available or easily accessible. The extended life battery that comes standard with the cordless line of Black & Decker A18 drill battery is longer lasting than other similar tools available. This together with the durability and simple accessory swapping that Dewalt power tools provide, and you can easily understand why they are so popular and in high demand. DeWalt Cordless Tools are built for every day routine and heavy-duty applications.

Hitachi tools – Hitachi tools are the most reliable products available. If you buy Hitachi, you can be ensured of buying quality products that won’t cost a hole in your purse. It has an impressive line of tools and because of the huge range; it is easier for you to choose. Everything from band saws, circular saws, cut-off saws, miter saws, reciprocating saws, drills, drill presses, drivers, hammer drills, etc. are available. With Hitachi, you can be assured of top- quality results that will please you. Never buy a tool without expert review.

It is a good idea to spend some time with a professional.

Bosch tools – Bosch tools are the best in the industry of tools. They are the most trusted name anyone can think about. They are the oldest player in this field. The Bosch tools are synonyms with the uniqueness and the comfort. They provide better output and that is the reason they are highly trusted. This is not because it is one of the oldest but because of the deliverance by the Bosch tools. They have given the best of the result with all the satisfying result. No one has questioned their loyalty. That has made them the champion for the long time.

There are many other cordless power tools and equipment that anyone can use for everyday situations. However, it is also useful to understand that these come in many different brands, types, and prices of Black & Decker HPB18 battery. While you may get a good bargain for discounted tools, purchasing original, durable and branded items are proven to be the best option for long term use.

Batteries Are the Key of the Cordless Power Tools

Hitachi power tool batteries are the key to any cordless power tool, whether choosing a cordless drill, hedge trimmer, leaf blower, or any other type of cordless tool. Battery voltage is not the single most important factor to consider when choosing cordless power tools. With cordless tools available all the way up to 36 volts, amperage/hour, and battery type must also be taken into account. Many 14.4 volt tools will outperform 19.2 volt tools due to battery type and amp/hr rating.

Battery Rating Basics

Amperage hours and voltage are used to rate a cordless tool battery. Amperage hours are used to determine how long a battery will last and voltage refers to the flow or strength of the electrical current. As I was taught in high school shop class the theory of electrical current is easier to understand if you think of it as water being pumped through a pipe.

•Voltage is used to measure the speed at which water is flowing through the pipe.
•Amperage represents the size of pipe that will be filled to capacity.
•Amperage hour rates how long the flow can be maintained or how long the battery will last.

As you can see by using this analogy the higher the voltage in conjunction with higher amp/hr the stronger the battery. Panasonic power tool batteries are usually available in 1.4, 2.4, and 3.0 amp/hr. The amp/hr rating of the battery can be found on either the side or bottom of most batteries.

Battery Types

There are three types of batteries used in modern cordless power tools.

• Ni – Cad ( Nickel – Cadmium ) are the oldest type used and are prone to developing a memory and early failure. Even when properly maintained they are lucky to be recharged 400 times before failure occurs.
• Ni -MH ( Nickel Metal Hydride ) are a newer design than Ni – Cad and can develop a memory, though not as quick. The worst issue discovered with this type of battery, the higher the amp/hr rating, the fewer charge cycles before battery failure occurs.
• Li – Ion ( Lithium – Ion ) are the newest type available and much better, compact, and expensive than the other two types. Memory is not a problem, and manufacturers claim up to 1,200 charging cycles before replacement.
Charging Time

Is another important consideration when considering cordless power tool batteries. Many older batteries need charging after only an hour or less of work and require six hours of charging time. If you have a lot of work to perform can you afford to wait for your batteries to recharge? There are Lithium – Ion batteries available that only require 15 minutes to recharge.

Stability and Maintenance

With the high cost of replacement batteries for cordless tools it pays to follow manufacturers recommendations for the care and maintenance of these tools. Cordless power tool batteries are just like any other piece of equipment and have an expected service life. When they become worn out and need replacing it is sometimes more economical to replace the entire tool kit. The cost of two replacement batteries is often times more than a new cordless tool with charger and two Ryobi power tool batteries.

Jumpstart a Power Tool Battery and Bring It Back to Life

When your power tool battery charger displays the dreaded flashing red light, it usually means it’s time to get a new battery. But before you get rid of that Panasonic power tool batteries, try this trick to bring it back to life.

First, a disclaimer: We don’t advise hacking or tampering with your lithium-ion batteries beyond what the manufacturer recommends. If you get a battery failure, read the instruction manual or contact the manufacturer directly for repair information. Basically, it’s dangerous to play around with batteries, as they can be a fire and explosion risk, so proceed at your own risk.

That said, cordless battery replacements aren’t cheap, and this has spurred a few creative individuals to try jumpstarting their batteries with seemingly good results. They set up a seemingly dead battery next to a fully charged one, and using two wires, they connect the matching polarity between the two batteries. After a few minutes the bad battery is then placed on the charger and (with any luck) starts charging again.

This may be only a temporary fix, and even if it works an underlying Hitachi power tool batteries problem may still exist. But if you’re brave, you might be able to coax new life from an old battery.

Is 21.6V Cordless Vacuum Cleaner Stronger Than 12V Cordless?

Probably! Answer is not that simple…

Nominal voltage of lead acid battery cell (today rarely used in cordless vacuums, but these are still present in cars, UPS devices, boats etc) is 2V, NiCd and NiMh cell voltage is 1.2V and lithium battery cells have around 3.6V – keep this ‘around’ in mind for lithium batteries, since they come in various versions and chemistry that vary slightly and their cell voltage can vary a little bit.

For example:
– 6V SLA (Sealed Lead Acid) battery has 3 cells,
– 12V SLA battery has 6 cells,
– 12V NiCd or NiMh battery has 10 cells,
– 14.4V NiCd or NiMh battery has 12 cells,
– 7.2V lithium battery has 2 cells,
– 14.4V lithium battery has 4 cells,
– 18V lithium battery has ONLY 5 cells.

We say ‘only’, since power of cordless vacuum cleaners is (actually, it is the same for both cordless and corded vacuums):

Power (W) = current (A) x voltage (V)

So, for the same power, if voltage is increased, current can be decreased. Weaker current means lower power loses in cables, but also less stress to the Dyson 912433-04 battery.

Newer batteries do cost more, especially lithium batteries, but they come with increased both voltage and capacity and with reduced weight. So, newer models come with motors optimized for higher voltages, draining the same or even stronger currents. Therefore, if newer cordless vacuum cleaner has increased voltage from 12V to 18V and capacity from 3.5Ah to 7Ah, with the doubled current than before, then:

– power is increased 3 times, for example from 100W to 300W,

– operating time is increased since newer Dyson 917083-01 battery with 7Ah capacity can be drained little bit longer with 2x stronger current than older 3.5Ah battery due to lower capacity loses when battery is drained with stronger current, for example, if older vacuum operated 15 minutes at full power, then new model will probably operate at least 20 or even 25 minutes.

Physics, Chemistry, Math … Who doesn’t love them?!

Anyway, as this examples clearly demonstrates, newer battery types is the way to go when performance is required – meaning lithium Dyson 17083-2811 batteries.

For cheaper cordless vacuums, NiMh batteries are still great power source that will still be around for years.

MacBook Air is Still One of the Best Laptops You Can Buy

The Insider Picks team writes about stuff we think you’ll like. Business Insider has affiliate partnerships, so we get a share of the revenue from your purchase a battery for laptop.

Apple’s products are well-known for many things, but being on sale isn’t one of them.

But for a limited time, you can save $50 on a MacBook Air thanks to Amazon.

It might not be as small as the MacBook or as powerful as the MacBook Pro, but the Air is still a perfectly good machine for day-to-day use — I’m typing this article on one right now.

The 13″ MacBook Air is a balanced machine — it’s thin, light, powerful, and gets great battery life, but it doesn’t have any of the flashy new features that set its siblings apart.

It has two USB 3.0 ports that work with your current accessories, an SD Card slot for photos, and a Thunderbolt 2 port to connect to a dock or high-resolution monitor. The keyboard is also Apple’s older version, which has more key travel but smaller key caps, and a MagSafe connector for power.

For most people, this baseline Apple MacBook batteries will be a great machine; if all you do is watch Netflix, write e-mail, browse the web, and post on social media, you’re going to be fine. People with more power-hungry needs will push the Air and see it struggle, but I’ve even been surprised at how well it handles high-resolution image-editing.

I should also point out that this is the second newest version of this laptop. Apple recently gave it a minor processor boost, although it’s not big enough to make much of a difference.

Like I said earlier, if you’re an average computer user, this MacBook Air is going to serve you just fine. I’ve used it every day for over a year, and it’s still pretty fast. It slows down if I have a lot going on at once, but that’s more of the exception than the rule. The only people I could see getting upset at this computer’s performance are those who really need a powerful machine, or want features like USB-C and the Touch Bar.

It might not be forward-looking, but this is a computer I’m happy to be using on a daily basis, and won’t have problems using for the next few years. You can use it with the accessories you already own, upgrade it if your needs do change, and save some money in the process.

Whether you’re going to college (or know someone who is), or just want a reliable computer that doesn’t have every cutting-edge feature, this is a good deal. You’re getting a machine that’s made for efficiency and consistency, which isn’t a bad deal.

Your Rechargeable Power Tool Batteries Caring

Whether it’s a rechargeable battery inside a smartphone, tablet, or laptop, here are a series of tips to help you get the most from it.
Read Less

There’s a lot of voodoo written about how to take care of the rechargeable batteries inside smartphones, tablets or notebooks. While a bit of care can make all the difference, you don’t need to treat the battery like a sick pet. It’s been designed and built to do a job, so most of the time you can just let it get on with that job.

But with a little bit of care, a rechargeable Panasonic power tool battery can last years. How much of a difference can taking care of the battery actually make? In my experience, the answer is “a lot.”

I have both a second-generation iPod nano that I bought around December 2006, and a first-generation iPod touch I picked up in 2008 that still have the original battery installed, and they both work. Eventually, the batteries will wear out, but I won’t be complaining that I didn’t get my money’s worth out of the battery!

Understand the “recharge cycle”

Every battery has a finite lifespan, and this is given as the “recharge cycle” or “battery cycle.” Put simply, this is the number of charge/discharge cycles that a battery is expected to endure before it is no longer fit for service. Some hardware manufacturers publish this figure while others do not. For example, Apple makes this information available, stating that the iPhone battery is designed to retain up to 80 percent of its original capacity at 500 full charge and discharge cycles, while the MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles before it reaches 80 percent of its original capacity.

You can find out how many times your MacBook’s battery have been recharged by clicking on the Apple logo on the menu and then About This Mac, followed by the System Report button. From there, click on Power under Hardware and look for Cycle Count.

For a Windows 8 or Windows 10 system, fire up a Command Prompt and type in:

Full discharge vs. Partial discharge

Some people say that you shouldn’t allow a Li-Ion battery to become fully exhausted before recharging, other people say it doesn’t matter.

The truth is, with modern Li-Ion batteries it doesn’t really matter because their discharge is closely regulated by on-board circuitry.

This used to be an issue with the old NiCd (Nickel Cadmium) Ryobi power tool batteries because they could discharge to such a point where they would become impossible to recharge (those batteries also didn’t like being charged too often and were much more sensitive to temperature). The same goes for lead-acid batteries, which also don’t take too well to being discharged too much unless they are rated for “deep cycle.”

Use the proper charger

I’m a big believer in using the right charger for the right device.

It might be more convenient to pack one charger and a bunch of cables for trips, but for long-term usage you’re better off using a charger designed for your device because that’s delivering the right amount of power for the battery. Regularly using a charger that delivers too much or too little power will ultimately affect the longevity of the battery.

If you are going to go down the third-party charger road, then make sure they are from a reputable brand. No-name junk might look and feel like an original charger, but based on testing I’ve carried out I’ve found that what comes out of the cable can vary wildly. I’ve also seen cheap chargers pour out masses of acrid smoke, or even blow up while plugged in. Those aren’t the sort of dramas I like to see happening at home or in the office.

Does it really make sense to hook up a $500 tablet to a cheap dime-store charger? I don’t think so! While battery for power tool protection circuits built into devices do a good job of shutting off any power that could damage a battery, poor quality chargers can still do a lot of damage, causing voltage spikes and overheating.

Long Live Your Laptop Battery

Laptop batteries are like people–eventually and inevitably, they die. And like people, they don’t obey Moore’s Law–You can’t expect next year’s batteries to last twice as long as this year’s. Battery technology may improve a bit over time (after all, there’s plenty of financial incentive for better batteries), but, while interesting possibilities may pop up, don’t expect major battery breakthroughs in the near future.

Although your HP 751906-541 battery will eventually die, proper care can put off the inevitable. Here’s how to keep your laptop battery working for as long as possible. With luck, it could last until you need to replace that aging notebook (perhaps with a laptop having a longer battery life).

I’ve also included a few tips on keeping the battery going longer between charges, so you can work longer without AC power.

In fact, Vista and Windows 7 come with a setting for just this purpose. To see it, click Start, type power, and select Power Options. Click any one of the Change plan settings links, then the Change advanced power settings link. In the resulting dialog box, scroll down to and expand the Battery option. Then expand Critical battery level. The setting will probably be about 5 percent, which is a good place to leave it.

XP has no such native setting, although your laptop may have a vendor-supplied tool that does the same job.

Myth: You should never recharge your battery all the way.

There’s considerable controversy on this point, and in researching this article I interviewed experts both for and against. But I’ve come down on the side of recharging all the way. The advantages of leaving home with a fully-charged battery–you can use your PC longer without AC power–are worth the slight risk of doing damage.
Keep It Cool

Heat breaks down the battery, and reduces its overall life.

When you use your laptop, make sure the vents are unblocked. Never work with the laptop on pillows or cushions. If possible, put it on a raised stand that allows for plenty of airflow.

Also, clean the vents every so often with a can of compressed air. You can buy this for a few dollars at any computer store. Be sure to follow the directions on the can, and do this only when the notebook is off.

Otherwise, you’ll be wearing out the battery–constantly charging and discharging it–at a time when you don’t need to use it at all. You’re also heating it up (see “Keep It Cool,” above).

You don’t want it too empty when you take it out. An unused battery loses power over time, and you don’t want all the power to drain away, so remove it when it’s at least half-charged.

Never remove the battery while the computer is on, or even in standby or sleep mode; doing so will crash your system and possibly damage your hardware. Even inserting a battery into a running laptop can damage the system. So only remove or reinsert the battery when the laptop is completely off or hibernating.

If you’ve never removed your laptop’s battery and don’t know how, check your documentation. (If you don’t have it, you can probably find it online.) The instructions generally involve turning the laptop upside-down and holding down a button while you slide out the HP Pavilion dv7 battery.

Myth: Refrigerate your battery.

Some people recommend you store it in the refrigerator, inside a plastic bag. While you should keep a battery cool, the last thing you want is a wet battery, and condensation is a real danger in the fridge. Instead, store it in a dry place at room temperature. A filing cabinet works fine.

You don’t want the  MacBook Pro 15 A1286 battery to go too long without exercise or let it empty out entirely. If you go without the battery for more than two months, put it in the PC and use it for a few hours, then remove it again.

Also, before you take the laptop on the road, reinsert the battery and let it charge for a few hours before unplugging the machine. Allow the battery time to get a full charge before you remove the AC power.

The Important Cordles Drill Safety Tips

Using power tools can make a tough job much easier. However, they can also make simple tasks that much more dangerous. For that reason, understanding basic safety tips when it comes to operating a power tool like a drill can make a huge impact on personal safety as well as extend the life of the tools. This guide is designed to help both experienced and new drill users by reviewing proper drill use as well as 8 important drill safety tips that all Dewalt cordless drill battery users should know. In addition, a brief discussion at the end of this guide will give users helpful drill buying tips sure to save time, money, and frustration.

Proper Drill Use

Before going over the important drill safety tips at the heart of this guide, it is necessary to review the proper use of a drill in the first place. By making sure to use the correct technique, many safety hazards can be avoided. Proper drill use can be broken down into six simple steps:

Step 1

If using a corded drill, make sure that the electrical cord is long enough to reach to the project table. If using a battery operated cordless drill, make sure that the batteries are at full charge so that the drill will remain working throughout the project.

Step 2

Insert the chuck key into the drill to open the chuck. To do this, push the key’s nubbed end into the hole located alongside the chuck. Then, turn the key counterclockwise. Doing this should cause the teeth on the chuck key to engage with the matching teeth on the drill.

Step 3

Insert the proper drill bit into the chuck. Then, turn the chuck key clockwise to tighten it. Make sure that the bit is snug inside the chuck.

Step 4

Plug in the drill or attach the battery to its base and press the trigger to make sure everything is operating as expected. Do this before touching the Milwaukee cordless drill battery to the piece of work in order to avoid damage should something malfunction.

Step 5

Slowly press the drill bit down into the material. Make sure to apply a steady, light pressure. Maintain this pressure as well as keep the trigger engaged until the hole is drilled through completely.

Step 6

Without disengaging the trigger, slowly remove the drill bit from the material. Do this until the bit has completely cleared the hole. This will prevent the drill bit from getting stuck in the material just drilled.

Once a user is confident in the basic steps for proper drill use, it is necessary to take additional safety precautions in order to avoid injury while drilling. When users employ the proper techniques discussed above, these eight safety tips will help to keep the user safe.
1. Dress Properly

Prevention is the most important safety step anyone can take. This is just as true when working with power tools as it is when working with hand tools. Because of the rotary nature of power drills, specific precautions in terms of attire should be followed. This includes avoiding baggy clothing and long sleeves, pulling back long hair, and always wearing safety goggles.
2. Prepare the Drilling Space

Once the drill user is properly outfitted, the drilling space must be properly outfitted as well. This involves the physical space where a user plans to drill as well as the environment surrounding that space. Make sure children and pets are clear of the drilling area for their own safety as well as the safety of the drill operator. Becoming distracted while operating a power tool is a sure way to get hurt. In addition, remove any extraneous material from the area being drilled, especially loose material that could easily be sucked up into the rotating drill bit.
3. Charge the Drill Properly

Again, the steps taken before even handling the drill itself are essential to proper drill safety. When it comes to a cordless drill, which operates using a large battery pack at its base, this means properly preparing the drill battery before use. The temperature in the battery charging area should not be too cold or too hot as this could lead to a frozen or otherwise inoperable battery. Batteries that are too hot or too cold could malfunction once hooked into a drill.
4. Handle the Drill Properly

When moving the drill from the toolbox to a workspace, the way in which the user carries the unit is important. Power drills should always be carried by their base, not their tip where the bit is inserted. However, it is also important to never carry a drill by its trigger. Otherwise, an unsuspecting object or individual may get hurt. Drills with removable batteries should always remain separate from the battery units themselves until just before use.
5. Check the Drill

Similarly, before even setting up for a project, make sure that the drill itself is in working order. Even drills that have been successfully used before could have been knocked around and broken since their last use. It is also important to register any new drill purchased with its manufacturer and routinely check for recalls.

6. Secure the Piece

Equally important to the safety and security of the drill itself is the safety and security of the piece that is to be drilled. Secure loose items like boards or metal sheets with a clamp or other heavy object. This will serve the dual purpose of keeping the material steady so that the hole is put in the proper place as well as securing the material so it does not fly away and hit someone.

7. Drill Pilot Holes or Use a Center Punch

Either drilling pilot holes for screws or using a center punch, which marks where a hole needs to be drilled, is an important step in safety as well as drilling accuracy. A center punch will provide a small indentation in the wood which will orient the drill and also prevent slippage once the drilling has commenced.

8. Mark the Depth

Finally, when a user needs to drill holes of a particular depth into a larger piece of material it is important to mark that depth onto the drill bit itself. This way, the user can be sure to accurately drill without going over and ruining a project or going under and needing to start again. A great way to mark this depth is to do so with a thin piece of electrical tape wrapped around the bit at the proper depth which will clearly alert the user to when the depth has been reached.

Buying a Drill

Safety is of the utmost importance any time one is using a power tool, and safety starts with making sure that the tool itself is in the best possible condition. This starts when a power drill and the associated drill bits are purchased in the first place. In today’s market, there are literally dozens of choices for purchasing a Ryobi cordless drill battery or any other power tool. This includes traditional hardware stores, big box retailers, and tool supply chains. However, to combine choice, convenience, and price, savvy shoppers may want to look into buying a drill on

How to Shop for a Drill on eBay

The eBay marketplace is home to more than 100 million active users that includes both buyers and sellers. Signing up for an account is easy and includes the use of PayPal, a secure payment system that protects personal financial information by keeping it just between buyers and PayPal.

Once this process is complete, users can begin the search for a drill through eBay’s Home & Garden Shop. There is a special section dedicated to power tools, which includes accessories like drill bits along with a huge selection of both cordless and corded drills. Searching for the right drill or drill accessory is as simple as scrolling through these pages or conducting a basic or advanced search right from the eBay home page.


Working with power tools is a great way to save time and effort when completing a project at home or on the job. The benefits of modern technology allow jobs to get done more quickly and workers to pay more attention to the details that make a project great. However, there are also inherent dangers that come from working with power tools since their strength poses more of a risk than traditional hand tools of the same nature.

When it comes to operating a drill, safety starts with proper technique. This guide began by discussing drilling technique in six easy steps. After technique is understood, however, there are an additional 8 important drill safety tips that any operator must learn and abide by. This includes preparing oneself for the project, properly treating the drill itself, as well as taking precautions while using the drill. By following these tips and using quality drills and accessories acquired from reliable sellers on sites like eBay, drill users can rest assured that they will be not only be effective in their efforts, but also be safe.

Rebuild Your Own Lithium-Ion Cordless Drill Battery

Cordless drills are useful around the home for repairs and building projects. Most cordless drills run on a rechargeable lithium-ion battery. After a while your drill’s battery may start to lose charge quickly, or not sustain a charge at all. In most cases, this problem is caused by the drill’s charging unit, or the battery pack itself. While you can rebuild your Hitachi drill battery pack yourself, it requires that you take it apart, which may void your drill’s warranty.

Remove the battery pack from your drill or charging unit. Relocate the battery pack to a flat work surface. Determine how the battery pack is held together. In many cases you just remove a few Phillips screws. Otherwise, you may have pry apart or cut open the battery pack’s housing.

Insert a soldering chisel tip into your soldering gun. Plug in the gun’s power cord, and allow the tip to heat up for about five minutes. Locate the crease on the battery pack separating the pack’s top section from the bottom section. Firmly press the heated chisel tip to the crease, and run the chisel tip along the battery pack’s casing to cut it open. This step is optional if your battery pack is fastened together with screws.

Pull apart the top and bottom sections of the battery pack’s housing. This will reveal the battery cells bound together inside the battery pack’s casing. Use a utility knife to cut away the adhesive securing the battery cells inside the pack’s housing. Lift the bundle of Ryobi drill battery cells out of the pack’s housing, and set them aside.

Number each battery cell with a permanent marker, and examine the polarity alignment of the battery cells. Determine which side of each battery is positive and which negative (-). Use a battery tester to figure out which battery cells are dead, or going dead. Turn on your battery tester, and touch the positive probe to the positive end of each battery. Make a note of what battery cells are dead.

Remove the dead battery cells from the bundle. Use a utility knife to cut away the adhesive securing each bad battery cell in place. Use your heated soldering iron to desolder the wire connectors from each battery cell. Dispose of the removed cells.

Place the new battery cells into the empty slots in the battery bundle. Make sure the polarity matches the rest of the cells in the bundle. Use your soldering iron and fresh solder to connect the battery wire connectors to the positive end of each battery cell.

Wrap the entire bundle with electrical tape until all cells are secured to the bundle. Place the cell of cordless drill batteries into the battery pack’s bottom housing. Replace the top section of the housing, and replace any retaining screws as needed. If you had to cut open the battery pack, wrap the battery pack with duct tape several times until the top and bottom sections of the casing are secured together.
