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 www.drill-battery.com.au.

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.

Changing Bits on a Keyless Cordless Power Tools

Loosen the chuck. The chuck is piece on the end of the Dewalt tool battery that loosens and tightens to hold the bit. Grasp the chuck with one hand while you hold the handle of the drill with your other hand. Twist the chuck counterclockwise to loosen it. Loosening the chuck will open the jaws that clamp onto the drill bit.

Remove the bit. Once you loosen the chuck, the drill bit that you currently have in the drill will start to wobble. You should be able to easily pull it out of the drill once the jaws that clamp it to the drill are loose. Always inspect the bit when you remove. If it looks damaged or worn, throw it out so you don’t accidentally use Milwaukee tool battery again later.

Set the bit. Hold the bit with your thumb and index finger so that the smooth part of the bit (the shank) is facing the jaws of the chuck. Insert the bit into the chuck and immediately pull it back towards you about a centimeter. Keep your fingers on the bit and the chuck since the bit isn’t secured and could fall out.

Squeeze the trigger. Tighten the bit into place by giving the trigger a few short squeezes. Your other hand should still be loosely holding the bit in place while you do this. Lightly holding the bit while squeezing will ensure that the bit is installed straight.

Engage the ratcheting mechanism if needed. If your Ryobi tool battery has a ratcheting mechanism to apply extra pressure to the shank of a drill bit, you’ll need to click it into place. To engage it, firmly twist the ratcheting mechanism next to the chuck in a clockwise motion.

12V Milwaukee Power Tool Battery Specifications

Nearly all car, motorcycle and tractor Milwaukee M12 batteries are 12-volt, lead-acid batteries. These batteries can provide hundreds of amps of electrical current for a short period of time. This is why these batteries are commonly used in automotive applications.

Not all 12-volt, lead-acid batteries are interchangeable, however. It is important to consider the automobile’s electrical requirements before attempting to install a 12-volt battery.

Battery Voltage

Even though most car, motorcycle and tractor batteries are sold as “12-volt” batteries, the nominal voltage of a fully charged battery is closer to 12.6 volts. The electrochemical reaction between the lead plates and the battery electrolyte is what produces the voltage differential between the positive and negative terminals on a battery. Over time, the lead plates within the battery will become covered with lead sulfate crystals. These crystals inhibit the electrochemical reaction between the lead plates and the electrolyte, causing a drop in Milwaukee 48-11-2401 drill battery voltage.

Electrical Current Capacity

The electrical current capacity for each battery is rated using two metrics: “cranking amps” and “cold cranking amps.” Cranking amps are a measure of how much electrical current (as measured in amps) a battery can provide for 30 seconds at 32 degrees Fahrenheit. Cold cranking amps are a measure of how much electrical current a battery can provide for 30 seconds at 0 degrees Fahrenheit. Since the electrochemical processes that produce electrical energy in a battery are affected by cold temperatures, a battery will always produce more cranking amps than cold cranking amps.

Reserve Capacity

If the alternator (or generator in some older vehicles) fails, the Milwaukee C12B tool battery is the sole source of electrical power for that vehicle. Batteries are designed to operate for several minutes in the event of an electrical failure.

A battery’s “reserve capacity” is a measure of how long, in minutes, a battery can deliver 25 amperes of electrical current during a charging system failure.

Does a Larger mAh Number on Your Cell Phone Battery Mean a Better Battery

An ideal cell phone battery has a high mAh capacity, but it also has many other important features. A battery might have a very high mAh rating but if it does not hold a charge well, it is not a better battery. The type of battery influences the battery capacity in mAh and many other characteristics. The latest TOSHIBA PA3817U-1BRS battery types using lithium score the highest on essential features. They are generally better batteries, even when the older nickel batteries have a higher mAh number.


The mAh or milliampere-hours of a battery measure how much charge it can hold, and how long it will operate your cell phone before it needs recharging. A 1000 mAh battery can supply 100 milliamps for ten hours, while a 2000 mAh battery can supply the same current for 20 hours. A larger mAh number on your cell phone battery means you don’t have to recharge the battery as often. If the new battery is the same as the old one in all other respects, it is a better battery.
Nickel Cadmium (NiCd)

Batteries containing nickel and cadmium are the oldest type of rechargeable batteries. They are heavy and they don’t hold very much charge for a particular size of battery. To avoid damaging the battery with the “memory effect,” they have to be discharged fully and recharged fully or they lose capacity. If a lithium battery has a higher mAh number than a nickel cadmium battery, it is very likely a better TOSHIBA Satellite L750 battery.
Nickel Metal Hydride (NiMh)

Replacing the cadmium in nickel cadmium batteries with metal hydride improves battery performance. The NiMh batteries are lighter and have a higher capacity. The memory effect is not as strong so that the batteries only have to be fully discharged and fully re-charged occasionally to retain full capacity. A NiMh battery with a higher mAh number than a similar NiCd battery is a better battery.
Lithium-Ion (Li-Ion)

Lithium is a much lighter metal than nickel, and batteries containing lithium are lighter and more powerful than nickel batteries. As of the date of publication, the lithium-ion battery is the most commonly used type of cell phone battery. It can be charged at any time since lithium batteries are not subject to the memory effect. If a lithium-ion battery has a higher mAh number than a nickel battery, it is likely to be a better battery.
Lithium Polymer

The lithium polymer battery is a further development of battery technology and has a similar capacity than lithium-ion batteries but at a lower price. This type of battery is still not very common as of the date of publication. A lithium polymer battery with a higher mAh number than other types of TOSHIBA Battery Pack is probably a better battery but it is still hard to find.

How to Revive Lithium Ion Power Tool Batteries

Lithium ion batteries come in a pack and are used in laptops and camcorders. They are rechargeable, but only when placed in the device that it is used in and possibly plugged into the wall. Some items will charge the battery when the battery is placed inside the device, and sometimes the device needs to be plugged in to charge the battery. Sometimes you might think this battery is dead, but there is a nifty trick you can try that might bring your battery back to life. This will save you the time, money and hassle of buying a new power tool battery.

Turn off the power device where the battery resides and remove the battery.

Securely wrap the battery in a relatively thick layer of newspaper, securing it with regular tape or masking tape. Masking tape will work better in sub-zero temperatures.

Stick the battery in the freezer for three to seven days.

Remove the battery and allow it to sit overnight wrapped in the newspaper.

Remove the newspaper. If the battery is still cool to the touch, then wait until it is at room temperature. You do not have to rewrap the Dewalt power tool battery.

Put the battery back into the laptop or other device. Do not turn it on. Allow the battery to charge fully before turning on the laptop. You will know the battery is fully charged when the green light comes on the charger.

If your electronic device is still under warranty, send off for a new battery because this will last you much longer in the long run. If the cordless drill battery is warm when you put it in the freezer, the casing might crack. Let it sit at room temperature for a while.

Recycle Your Cordless Tools

The materials found in cordless tool batteries are recyclable. Manufacturers reuse the materials to assist in the manufacture of new products. While it is not mandatory to recycle cordless tool batteries in each state, the states of New York and California do enforce such laws. Recycling Makita tool batteries has a positive effect on the environment and helps to reduce hazardous spills at landfills.

Remove the battery from your cordless power tool. Cordless power tools vary by model type and manufacturer, so refer to your owner’s manual for complete battery removal instructions.

Go to Call2Recycle’s website, which belongs to The Rechargeable Battery Recycling Corporation, a nationwide battery disposal organization.

Locate battery recycling facilities across the Unites States and Canada using the “drop off locator” tool.

Find a cordless power tool battery disposal and recycling center in your state. Enter your zip code and choose the nearest location.

Drop off your battery or arrange pickup if a drop-off facility near you is not available. Recycling services are available free of charge.

Alternatively, recycle locally. Contact a replacement Hitachi tool battery store in your town and inquire about recycling services. Drop off your cordless power tool batteries as directed.

Contact an organization such as Workaid and Tools for Self Reliance if you wish to recycle old work tools. These and other organizations accept tools in poor condition and then refurbish and distribute them for work projects in developing counties.

How to Choose Power Tool 18V Battery Types

The 18-volt or 18v Hitachi tool  battery powers most power tools, from cordless drills to jig saws. While all the types of 18v batteries power tools offers are rechargeable, there’s a wide range of value, charge life and cost you need to understand when shopping for batteries. Find DeWalt batteries at your local hardware or construction supply store, or order them online. If you don’t have a battery charger, you’ll need one; you can find multi-type chargers that will charge any of power tools 18v batteries.

Purchase 18v nickel cadmium (or NiCad) batteries if you are a casual drill user or if you need to purchase the least expensive battery type. While nickel cadmium batteries are rechargeable, Michael BlueJay’s website, a well-known website reviewer, terms them “obsolete,” you get very few recharges and they last 50 percent less than nickel-metal hydride Panasonic tool batteries.

Buy nickel-metal hydride batteries if you use the drill semi-regularly and want a good value battery. These batteries go dead if you don’t use them for some time, so they make poor casual-use batteries. But they are easy to find, relatively inexpensive and offer a long life and recharge function.

Purchase lithium-ion batteries for the most value for your money. These are more expensive, but they have a long life, recharge well and don’t lose a charge when not in use like the nickel-metal hydride batteries do. InfoBarrel notes that these can be recharged 2,000 times, making them a good AEG battery value for the heavy drill user or the homeowner who plans to use the drill occasionally for many years.
