Reanimate Old Drill Batteries

I was in dire need for a Dewalt battery for powered drill, but my good one was at my local Makerspace and I could not be bothered to drive over there at 0100 in the morning.

I remembered that I had bought one some 15 years ago in a supermarket. After I dug up my basement looking for it, I found it in the store-room with a dead battery.

I will show now what I did to reanimate it, for fun and… fun.

Step 1: Take Apart the Battery

The battery pack was held together with 4 screws. After loosening them, it fell apart into three pieces:

Old batteries (dump)
Top cover with contacts (need new wires to go to the new battery)
Llower case (needs holes for battery wires to go through)

Step 2: New Energy

I decided to use a lipo battery pack as my new power source. My drill originally had a 12V power source, so I needed a 3 cell LiPo pack.

I had an old cordless drill battery for Panasonic with a broken cell sitting on my desk for ages, and took the occasion to finally rip it apart to build a new battery out of it.

This is quite easy, but I found no instructable detailing how its done.

Step 3: Build Top Case Connector

Easy step, find a matching battery cable, solder it to the contacts in the top case.

Maybe your drill is old enough that it doesn’t matter, but watch out for polarity anyways!

I want to have the battery connector outside of the plastic case, thats why I left the cables that long.

Step 4: Lower Case

Now I had a problem. I needed to drill holes to get a working battery for my drill. The Hitachi cordless drill battery was empty (after sitting on my desk for month).

Adjustable desk power supply to the rescue!

I put 2x two holes next to each other, broke out and filed of the middle to have two long holes.

Step 5: Assembly

The battery fits nicely. The reason why I wanted to put the wiring on the outside is:

I need a easy way to access the balancing port for charging and use of a lipo warner (recommended)
I want to be able to disconnect the lipo from the contacts

Happy drilling!

Right Way to Take Care of Your Laptop Battery

You probably know a few tricks for extending your laptop’s battery life—whether it’s dimming the screen or switching off Wi-Fi—but there are plenty of other ways you can and should look after its long-term health too. Here’s how to get the most juice out of your laptop by following just a few simple rules.

Every laptop battery degrades over time, but you can help to make sure it stays in fine fettle to a ripe old age by heeding the advice we’ve laid out below. With some care and attention you can make sure your laptop needs replacing before its battery does.
Temperatures and cleaning

Operating temperatures can have a big impact on battery life: check the manufacturer’s guidelines for the ‘safe zones’ for your laptop, which are usually different depending on whether you’re storing your computer or actually using it. For an accurate read of how hot your laptop is, OS X users can turn to Temperature Gauge, which will set you back five bucks but give you more temp info than you’ll know what to do with. Windows users might want to look at Rainmeter, a free system monitor that displays all kinds of visually pleasing goodies—temperature included.

Generally speaking, room temperature (or as close as you can get) is ideal. That means you shouldn’t leave it lying in a packed trunk in the height of summer or on the window ledge of your skiing chalet. If you’re at an uncomfortable temperature while you’re working, then your laptop’s battery will be too, so make adjustments accordingly.

Watch out for excessive heat, which is particularly unhealthy. If you have a tendency to use your laptop whilst wrapped up in bed or stretched out on a sweltering Caribbean beach then the battery’s going to give up the ghost sooner. Keep it cool and on a flat, stable surface as much as possible, and make sure the cooling vents are clear and unobstructed. Invest in an extra stand or fan tray if necessary.

For those of you with a removable laptop battery, take it out and clean the metal contacts at either side once every couple of months with a dry cloth and alcohol solution—this helps to keep the transfer of energy to your computer as efficient as possible.
Keeping the juices flowing

To ensure the battery in your laptop has a long and healthy life, avoid leaving it constantly charged. It’s important that the electrons inside are kept moving on a regular basis—think of it as being akin to getting up to exercise rather than sitting at a desk all day. Broadly speaking, the less frequently you use your laptop, the less frequent the discharges need to be.

Ideally, you want to be draining your laptop’s battery to around 40-60 percent at least once a week. On top of this, fully discharge it and recharge it once or twice every year. In other words—as far as the electrons inside your Dell laptop battery are concerned—the routine should be regular weekly appearances at the gym and a 5k run in the summer.

The reason behind this is that a full charge puts your battery under more stress. If a laptop is plugged in all the time, the battery is working harder than it would be if it was slowly cycling between 40 percent and 80 percent. Some experts recommend removing the laptop battery entirely when the computer’s plugged in to avoid overheating, particularly for intensive tasks. Letting your battery run all the way down every so often also helps calibrate it, making for more accurate power display readings.

There are rules for long-term storage too. If you’re going somewhere without your laptop for more than six months then it’s a good idea to store it with a 40-50 percent or so of juice left. Leave it fully charged or fully discharged and you run the risk of causing damage to it while the computer is in hibernation.
Power settings

A few little tweaks to your laptop’s power-saving settings can make a significant difference to the level of juice you have left at the end of the day, and the less work your battery does, the healthier it will stay. Open up your laptop’s power saving settings (Control Panel >> Hardware and Sound >> Power Options for Windows users, System Preferences >> Power Saver on an Apple machine) to make changes.

The basic settings cover the screen and computer state, while the advanced settings link on Windows lets you adjust power-saving options for the hard disk, Wi-Fi adapter and USB devices. If you’ve never delved into this screens, try reducing the time it takes before your laptop goes to sleep and switches the screen off.

Your laptop manufacturer may have added a special utility or two for battery management, so have a poke around in the pre-loaded applications list to see what you can find. If you want to keep your laptop on for as long as possible, reduce its workload as much as you can: lowering the screen brightness, shutting down unnecessary applications, limiting your browser tabs and unplugging devices you’re not using can all help. For Mac, you can also download Battery Health for free for deeper insights into how much juice you’ve got left, while Windows users can turn to BatteryCare for similar services.

Again, any way in which you lessen the amount of work your Acer laptop battery is doing can help to prolong its performance in the long term. Finally, be wary of using a charger or plug other than the one supplied by the manufacturer, as anything less than optimum compatibility has the potential to cause damage.

How to Maintain Your Cordless Drill Easily

Whether you are a general contractor building and a room addition or a do-it-yourselfer installing speaker wire for your new surround sound system, the cordless drill or driver is a vital part of your equipment. Furthermore, reliable cordless machines can be a significant investment, and great care should be taken of one of your most valuable assets. High-quality products are typically very resilient to long term use, but even the toughest of drivers can break down quickly if regular maintenance is not performed.

Cordless drills differ from electric (corded) ones in that there are more parts which require proper attention. For example, cordless product batteries need their care to preserve the service life of the Panasonic cordless drill battery. These batteries can be expensive and need to be charged and stored properly to deliver enough power to the machine for the most rugged projects. The following information will help drill owners be better informed on how to preserve and even extend the life of their cordless models.

»Oiling Your Machine: Like other mechanical tools, your cordless drill has lots of moving parts inside and out. One of the most important parts of routine product maintenance you can perform is regularly oiling the metal parts of the machine. More specifically, oiling the chuck, which is the part that holds the bits.

»Most modern products come with a keyless chuck, but some products, like hammer drills, come with keyed chucks. Keyed chucks provide a better grip on bits. Especially when using a vibrating or hammer function on your machine, keyed chucks prevent the pieces from loosening over time. The following steps should be considered when oiling your cordless drill:

1.Using a standard metal lubricating oil, spread the oil on the inside of the chuck where the drill bits would go (make sure the chuck teeth are completely open).

2.Tighten and loosen the chuck three to four times to evenly spread the oil throughout the inside of the chuck.

3.Using a rag or shop cloth, apply the oil to the outer surface of the chuck. This will ensure oil is spread thoroughly between the chuck and the hand grip.

4.If the chuck is keyed, follow the above steps with the addition of lubricating the vital teeth around the outside of the chuck. This will reduce wear on the teeth of the core and the chuck.

»Cleaning Your Instrument: Penetrating through a surface is almost always a messy job as the drill bit grinds through the material. Going through wood, drywall, and concrete, for example, can leave your machine quite dusty. The dust particles from drywall gypsum, for instance, are excellent and can easily work their way into the motor events of the drill. Overtime, these vents can become clogged with particles and dust, causing the engine to overheat and eventually burnout.

Only blowing the dust out of these vents will ensure the motor can breathe properly. It’s a vital step to keep it running smoothly.

You can use a blow tool if you have an air compressor, otherwise, an air duster or compressed air canister will also work adequately.

»Keep Your Drills in a Dry Place: These are very powerful tools, but that power is based on a vast number of small intricate motor parts, gyros, gears, and even small chipsets which can control speed and torque ratios. Always make sure your drill is stored in a dry space. Humid conditions can cause water vapor to get into the product, rusting the motor parts and the chucks of the machine. The battery can also be adversely affected by moisture and cause corrosion around the metal contacts that connect the battery to the drill.

»Temperature Requirements: Your product can also be affected by the temperature it is stored in, especially the battery. As best one can, the drill and batteries should be stored at room temperature (72F/22C) with a buffer of plus or minus 10 degrees. Freezing temperatures can cause icing of the motor and compression of the gears, effectively burning out the motor and gears. Excessively warm temperatures can significantly reduce the life of the power tool batteries, especially lithium ion batteries. There are some machines which are now equipped with cold weather lithium ion batteries for outdoor winter use. However, these batteries also need to stay out of hotter temperatures.

»Keep Your Drill Off of the Ground: This is another key to keeping your cordless drill clean. There is a high likelihood you will eventually use your project for an outdoor project. Grass and dirt can easily find their way into the casing when left on the ground. Moreover, wet grass and dirt can significantly damage your machine. Wet blades of grass can easily distribute water in through the motor vents, potentially causing a short in the drill or even electrocution. Leaving products on the ground can also be a safety hazard – especially on a job site where there is frequent foot traffic. Individuals may trip on the machine or even damage it.

»Use Sharp Drill Bits: The machine’s power is only as good as the bit’s ability to penetrate a surface. Using dull bits will not only fail to get the job done, but it can also burn out your machine’s motor very quickly. Dull bits will cause longer work times while simultaneously increasing friction and ultimately resulting in undue stress on the motor. Ensure your bits are sharp before starting on a project and make sure they are the correct bits for the surface through which you intend on AEG cordless drill battery. Do not use wood bits to go through concrete, for example.

»Drill Bit Safety: Dull bits can also present safety issues. If the pieces are not sharp enough, they can become jammed into the surface. The resulting torque can cause the drill to spin; injuring our hands and wrists. The machine may even fall out of your hand and onto the ground below. This can be especially dangerous if anyone is below you or if you are on a ladder, it may cause you to lose your balance.

How To Store A Battery When Not Using It

First of all, it’s best to keep using the battery for cordless drill. Use your tool at least once in 20 days. However, this is not always possible. Storing the battery the right way is also essential to its health and overall  life.

When putting away cordless tools for a long time:
1.Put the battery in a cool and dry place and away from dust.

2.Put it in the original plastic case it came in. Put in a box or wrap it in a soft cloth.

3.Do not store Li-ion batteries fully charged or dis-charged. Store them at 30-40% charge level. Do the same for Nickel based batteries, though it does not make too much of a difference as they lose their charge fairly quickly anyway. Many manufacturers will recommend that you discharge your Nickel based batteries completely before storage. Follow the manufacturers instruction if your battery for power tool comes with them.

4.Fully charged NiCd batteries lose charge quickly. 20-30% in 24 hours. 10% the day after that and 1% for every day after that. Be ready to charge your NiCd and NiMh batteries after a long period of rest before you can use them again.

5.Li-Ion batteries retain their charge for longer. Specially if they are kept in a cool place.

6.NEVER put your batteries in the refrigerator or the freezer. This can damage them permanently. Technically, NiCd pwer tool batteries can be stored at a temperature ranging from -20°C to 45°C. But freezing is still not recommended due to the possibility of ice build up. For a Li-Ion battery 15°C is about the ideal storage temperature. But as long as things are not overtly hot, they should be fine.

Ways to Take Better Care of Your Laptop Batteries

You likely spend more time on your laptop than with your significant other, your dog or — at the very least — your plants. So there’s no reason you shouldn’t treat it with the same tender loving care. Here are a few tips to ensure that your gadget’s battery has a long and happy life.

(This guide is focused on lithium-ion laptop batteries, which is what most modern laptops are packing. If you want to learn about how to care for other types of batteries, check out Battery University, a dense database of such things.)

1. Don’t get too attached.

When you plug your laptop in for the first time, you should make sure to fully charge it once to calibrate it. But after that, aim to keep it between 40 and 80 percent. Apple’s customer care says you should do this to “keep the electrons in it moving occasionally.” Wired has a better explanation of whyhere. But the bottom line is, doing this can help prolong your battery life by as much as four times.

I know that’s easier said than done. Just remember to keep an eye on your battery percentage (usually shown in a corner of your screen) throughout the day. If you leave your laptop at home, then shut it down, close it and keep it unplugged on a desk, not a couch.

You should also fully charge and discharge your computer’s battery at least once a month. Set a reminder on your phone or something. You forked over what I assume to be a ton of money for this thing, so paying attention to it once a month shouldn’t be a problem.

2. Stay cool.

Most modern laptops are made with lithium-based batteries, which should be stored in temperatures between 50 and 95 degrees Fahrenheit. You might not always be able to keep tabs on that sweet spot, so to make things a bit simpler, room temperature is fine.

That being said, there are a few ways you can make sure your laptop isn’t constantly having menopausal hot flashes. You should start by minding its air vents. Most MacBook vents are located on the back of the laptop, near the top of the computer. Whenever you prop your laptop up on your bed, couch or lap, you’re likely blocking the airflow. This, in turn, causes the computer to overheat. And overheating will screw up your Compaq laptop battery life.

That’s not to say you should be completely paranoid about keeping it on flat, cool surfaces all the time. But maybe consider moving it to a desk before you fall asleep or head to work.

3. Update, update, update.

Most companies are constantly looking for ways to improve battery life via software updates. In fact, it was one of the main things Apple touted in its OS X Mavericks release last year. You may fear change, but change can extend your battery life. So make sure you have the latest software installed on your computer.

4. Don’t just leave it there.

Maybe you’re in trouble with the law and need to disappear for six months. We understand how these things go. But that doesn’t mean you’re off the hook for correctly storing your computer. You should store it with a 50 percent charge in a consistently cool area. Storing the computer with a fully discharged laptop battery for Fujitsu might ruin the battery forever. And storing it with an absolutely full charge might cut the battery’s lifespan short.

Simple enough? Now go, be a better laptop owner. Your machine is counting on you.

Make a Power Tool Battery Multipurpose

My goal was to add an external power connector that would allow me to plug my battery up to whatever I wanted to while still being able to use it in my tools and the standard charger without any extra effort. This has been achieved.

Step 1: Gather Your Battery and Take It Apart.

For my project I used a Ryobi P108 battery. I was able to get several of them for a cheap price and I know these batteries are built using high quality Samsung INR18650-20Q cells. Also I have a large collection of Ryobi One+ tool battery so it was a win win.

So first, gather your battery. Figure out how it needs to come apart. My Ryobi is pretty simple. Has 4 Torx 10 security screws. One has a plastic cover that you have to remove by prying it out with a small screw driver or knife.

Step 2: Figure Out the Best Place to Add Your New Wires

For the Ryobi and probably all batteries, I think the best place to add your new wires is to the battery contacts where the current wires are soldered on.

Step 3: Solder on Your New Wires.

The Ryobi battery has 18awg wires coming from the circuit board to the contacts. I added 16awg wire for my modification. I figure that if 18awg is safe for the stock length, using 16awg for my short extension should be adequate. I also added a piece of electrical tape to help protect the wires from the connections stick out of the board. I also added a ziptie to each wire remove strain from the soldered connections.

Step 4: Modify the Case So the Wires Can Get Out, Cut Wires to Length, Add Your Favorite Connectors, and Put Back Together.

At first I was going to make one large hole for both wires to share, but then I realized the wires would fit better if they each had thier own hole. So I driled two matching small holes for the wires.

Once that was done I put the Metabo drill battery back together with the wires coming through their holes.

Next was to cut the wires to length, do them one at a time so you don’t short the battery.

Then add your favorite connectors, again doing the wires one at a time. My favorite is Anderson Powerpoles.

Step 5: Testing and Proof of Concept.

In the first photo I have the battery connected to my power meter then that is connected to my hobby battery charger. The Ryobi battery is powering everything.

You can see that the power meter shows 20.63v which is around what a fully charged 5S lithium battery pack should be. Not the 18v it is advertised to be. (18v comes from the NiCD battery days and Ryobi has not changed that nomenclature).

You can also see the battery installed in my Ryobi vacuum. You can see that the extra connector does not cause any obstructions. The battery will still fit into any Ryobi One+ tool as well as all their chargers.

Step 6: Multiple Uses – Only Limited to Your Imagination.

This can pretty much power anything. I have a ton of projects that I’ve done in the past years that this can be used with.

•RC Wheelchair
•RC lawn mower
•Power Wheel battey (other mods may be needed to handle the extra voltage)
•Wire 2 or more in series for even more voltage (A  power tool battery is not very different from 2 of these in series)
•Portable FPV ground station (most need 12v so add a DC to DC converter)
•Mobile device charger
•Emergency power supply

How to Use a Cordless Tool Safely?

A cordless drill is, no doubt, a handy tool that helps you with getting things done like a pro. But how do you use a cordless drill safely?

Drilling holes on various kinds of surfaces like wood, metal, concrete, brick etc. are common requirements in any household.

Rather than calling in a professional to get this done and paying a hefty fee for the same, you can do it yourself.

The benefits of doing those jobs yourself:
1.You can get them done at your comfortable and required time. If you want to get it done now, today, you don’t have to wait for the professional’s timing. If you want to get it done sometimes next week, you don’t have to worry about whether your technician will be available at that time or not.

2.You save money. Yup those technicians who help you with house projects are not cheap. I don’t expect them to be cheap since their kind of work deserves a fair fee. But what if you can do it yourself and save you that money?

3.You learn a few skills. That is impressive. Rather than relying on someone for something, if you learn a skill you need not wait or depend on anyone to get a job done. Besides, you can also flaunt on your new skill!

But so much we can talk about how easy it is to have a handy tool like a cordless drill and dive into DIY home projects, we should not also forget about the safety aspects.

Handling a cordless drill is not the easiest thing in the world – if you don’t know what you are doing you could end up hurting yourself or someone standing close by and also damage the surface (of whatever you were working on).

Which is why safety comes first.

And in this blog post let’s take a look at some of the safety aspects that you should consider while using a Cordless drill.

Wear safety gloves while you use a Ryobi cordless drill battery

You may wonder why! Depending upon the material you are working on, a pair of safety gloves will definitely help you with injuries that can happen due to various factors.

Think about the scrap that falls off when you work with metal and concrete.

Also the drill can get heated up due to intensive usage or prolonged usage.

In any case, operating a cordless drill without a safety glove is definitely not a good idea.

Safety goggles

While you are making holes or drilling down a screw, fine particles and/or tiny materials from the surface can hit your eyes.

If you are working with a metal surface, tiny sparks can also be emitted.

In order to protect your eyes from such particles and sparks, you must make sure you wear safety goggles when you work with a cordless drill.

Anyone who is standing near you while you work must also be wearing one.

Choose the right drill bit

An incorrect or inappropriate drill bit will lead to a bad job.

You must make sure you choose the right drill bit for that job.

Depending upon the surface you are going to work on and depending upon the kind of work (drilling a hole, fitting a screw etc.) you must choose the right drill bit that will just do the job fine.

Inappropriate choice of drill bit will not only ruin the job but can also lead to injuries.

Operate on appropriate speed and torque

All cordless drills have speed and torque settings.

Even if you don’t know anything about those numbers you should do some trial work without any surface to see what effects those settings bring in.

If you try to blindly operate the drill on a surface with a random setting you could do damage to yourself and to the Milwaukee power tool battery.

Most probably, your cordless drill came with a manual – and that should tell you about the speed and torque settings that you need you use for various surfaces.

Read the manual and use appropriate settings before you start working. Or you could even ask a professional about this.

Attend to the clog or binding

Clogging of drill bit is quite common, especially while working with wooden surfaces.

The saw dust can clog the drill pretty much easily.

And if you are working on metallic surface, the drill bit can bind when drilled into metal.

When you feel any of the above happening, just pause with whatever you are doing and check the drill bit for clogs or binding.

Carefully and gently clear that before you proceed with your drilling work.

Continuing to work with your drill with a clog or binding will cause damage to the drill.

Check on the chuck BEFORE you operate

Usually cordless drills have two types of chucks – keyed and keyless chucks.

You need a key to tighten a keyed chuck whereas a keyless chuck can be tightened using hand.

The chuck is the one that holds the drill in place. And if the chuck is not properly tightened it can be very dangerous to you as well as anyone else in the vicinity.

It is good to often check if the chuck is in place and properly tightened. And it is a MUST that you check the same before you start your work.

If the chuck is loose, it may fly off mid way causing enormous danger.

Overall clothing

When you need to do work with your cordless drill battery for Metabo you need to be careful with what you wear.

Depending upon the nature of surface you are working on, you might end up collecting a lot of dust on your clothing.

So stay away from wearing fine, branded and costly clothing.

You just need to be on a casual, comfortable wear and preferably wear a protective jacket.

Apart from wearing goggles and gloves, it is good to wear a firm, protective footwear too.

Stay away from wearing expensive jewellery – long chains are a sure NO as they might get stuck causing danger.

Safety comes first!

Yes – safety comes first with anything in life.

While a cordless drill can make your life a lot easier, it can be a dangerous tool if you don’t follow the appropriate precautions.

Hope this blog post gave you some important tips to use a cordless drill safely.

Run a Cordless Drill Off a Car Battery

Here is a quick way to recycle and reuse that old battery-powered drill with the dead or missing battery. Just wire it up to work off a car battery.

I seem to have portable drills that have Milwaukee drill battery packs that eventually fail. Sometimes I can get replacement battery packs but sometimes I can’t. I have seen workable drills with bad batteries at yard sales for just a few dollars. Recycle and reuse them.

In the example I show here I actually bought these cheap drills for the battery packs and chargers so I had the drills but no batteries.

Almost any drill powered by 9 VDC to 18 VDC battery packs can run off a car battery. Just add a convenient length of low voltage wire and a couple of battery clips and you have a handy recycled drill to use anywhere there is a 12 volt battery. I carry one in my car and have another one in my boat.

Some soldering is required but the whole project shouldn’t take more than about 30 minutes.

Obviously I should have searched Instructables before I published this. There are already a number of IBLs you can find by searching “12 volt drill”. So now there is one more.

Soldering iron
Electrical solder
Wire stripper

Drill with dead or missing battery pack
Landscape low-voltage 16/2 wire

Note: If you have a dead battery pack with your drill you can remove the old cells and run the wire to the contacts of the Paslode drill batteries. This may be a lot easier than trying to get up in the drill handle to solder directly to the contacts there.

I didn’t have the battery so I wired directly to the contacts in the base of the drill.

Decide on how long you want your cord to be. I have found a 10′ length of wire is a good general-use length. If you want to be able to reach any place around the opposite end of your car or boat then measure out what you need to reach back to the battery.

– Drill two side-by-side 3/16″ holes for wire to enter the base.

– Run the wire through oval hole into the battery pack or the drill base.

– Strip the ends of wire and tin them.

– Clean and tin the contacts in the drill base where the wires will attach.

– Solder the wires to the contacts.

– Tape over the base or reassemble the old battery case.

– Separate the free ends of the wire for about 6″.

– Tie an electrician’s knot (Pic 2) at the end of the split.

– Strip and tin the wire ends.

– Solder on the Dyson battery clips.

Note: It really doesn’t matter which wire is red and which wire is black. You will just change the direction switch on the drill to go forward or reverse.

In a car: buffer polish pad, drill mounting holes for switches and accessories, an electric screw driver.

In a truck: socket wrench with quick connect drill adapter, fence repair out in the field, portable paint stirrer.

In a boat: All kinds of drilling and polishing without any shock hazard from shore power and no battery to keep charged.

Now you have a drill that is easy to store, light and never has a dead battery!

How to care for a cordless drill driver battery

WONKEE DONKEE  has the following tips to help you care for your rechargeable batteries:

A hot battery is not a happy one!

When not in use, keep the AEG drill battery in a place that’s dry and cool. Don’t leave it in direct sunlight or near a radiator as it could explode!

Store your battery in a cool dry place that is free from dust and make sure that the contacts do not touch anything metal or the battery could overheat and cause a fire.

Most come with a protective cover for the battery contacts.

Don’t run the battery all the way down.

Some people, when they know the Black & Decker drill batteries is almost empty, will hold the speed control trigger in until the battery is completely drained and the tool stops running. This is known as deep drainage and can actually damage the battery and shorten its overall life.

All batteries need a little bit of life left in them to re-energise when you recharge them. Recharge the battery when the tool starts to slow down.

How to charge a detachable battery

In order to charge the battery, you need a charger. Most chargers have a slot designed to hold the detachable battery while it charges.

Some cordless drill drivers come with a charger included. However, if you have to purchase one, make sure you choose the correct charger for your battery.

It’s very important that you purchase a charger which is designed to charge your particular brand and voltage of drill battery for Craftsman.

This information should be printed on the charger and the drill driver’s battery.

Easy Nicad to Li Po Drill Conversion

I like to pick up early vintage cordless drills at thrift stores, they go for cheap especially if it has no charger and a dead battery, this vintage Sears 7.2 volt nicad tool went for $2 because it was the latter. I had on hand a T-Plug 11.1V 1500mAh 25C 3S VOK Discharge LiPO Metabo drill battery that runs for about $8 U.S., including shipping, and decided to use it for the hack. I’ve found from past conversions that the voltage disparity isn’t much of an issue, the D.C. motors used in these products are pretty robust and can stand a wide margin of abuse and still live a long life.

The contents of the following Instructable represent the experiences and outcome of the author, no guarantee is made as to suitability of the repetition of the information presented, therefore careful study should be undertaken by those wishing to duplicate these results, including a self- assessment of prerequisite skills, knowledge, and understanding of the subject matter.

The first step is to remove the defunct NiCad cells and clean up the contacts and the housing that transfer battery power to the drill. I soaked and scrubbed them in vinegar to dissolve acid and corrosion, then rinsed well to neutralize them. A test fit confirmed that little more need be done to incorporate the new Black & Decker drill batteries into the build.

I soldered a couple of 18 gauge wires to the contacts as down-leads to connect with the Lipo cells via a pair of insulated screw terminals instead of soldering them together, this would allow for easy replacement if it became necessary.

The only case modification I made was to provide the balance charger connector a feed-through hole to allow hookup to my charger, and by using a salvaged set of contacts, I can easily recharge and balance the drill batteryfor Paslode  without any issues whatsoever. The weight decrease is remarkable and the output power is fantastic, so for $10 U.S. it’s a deal for me.
