How To Fix A Drill Battery That Won’t Charge | Guide + Review

Fix a drill battery that won’t charge now has become a piece of cake. Many people think that they can’t get their drill’s dead batteries back to life. At the same time, it’s now just a myth. 

Lithium-ion batteries are an excellent modern-day marvel with one flaw. Sometimes they won’t charge up at all, no matter how many times we try. It can become quite frustrating after so much time has been spent trying unsuccessfully as well. 

There doesn’t seem like there’s anything else left then taking them back where we bought them from or throwing away this pricey piece of equipment altogether, right? 

But wait! What if you fix a drill battery without paying any extra cost or concerning any electrician? 

You heard me right. Now you do not have to buy a new $50 battery. You don’t even need to call your company and make a complaint because this stupid ‘defective’ battery is only two weeks old. 

Nor wait until they ship you a replacement before finishing up that project due in 3 hours (trust me!). All it takes is about 5 minutes’ worth of work on your end.

Curious about how you can fix a drill battery on your own? Okay, we are not going to wait for you anymore. Let’s begin this exciting and easy process to get back your drill battery’s life.

THINGS REQUIRED TO FIX A DRILL BATTERY

A DRILL BATTERY: Of course, keep your drill dead battery that won’t charge to fix it.

AN AC ADAPTER: You need an AC adapter. Because we will use it as a jumper cable, make sure that you use any old cell phone adapter because this will not be the same as before.

A MULTIMETER: This will help you to identify the voltages while fixing a drill battery. However, it is optional. But using a multimeter to improve a drill battery can make the procedure more accessible and fun.

So after collecting all the necessary stuff, move on to the step-by-step procedure to fix a drill battery.

METHOD TO FIX A DRILL BATTERY | STEP-BY-STEP PROCEDURE

You might be able to fix a drill battery problem by doing this. Try pulsing the power of your charger (with the battery in it) for 10 seconds and then unplug it again, a few times. If that doesn’t work, give our guide below a try.

STEP 1: You may have a pile of old AC adapters in the back of your closet, but cutting off their ends can be an easy way to make them functional again. All you need is scissors and some tape.

STEP 2: Separate and strip off 1″ of each wire. You have just made a quick and easy way to jump-start your drill battery.

STEP 3: First, open the battery by removing some screws. Underneath, you will find a screw that was hidden underneath another piece of plastic. It took a while to figure out how to get this off!.

It turned out two things were holding it in place: A small strip on the side and four tabs at each corner. Once these had been pried open with a tiny screwdriver, everything came free quickly enough.

STEP 4: With a swift motion, pull the top off of the battery case and set it on the ground beside you.

STEP 5: The drill’s battery is housed by two plastic pieces found on the side of your tool. To remove it, press them in and allow gravity to guide the process.

STEP 6: Now, you should locate the battery pack attached by a wire harness. Take it out so that you can replace the damaged cables underneath.

STEP 7: To find out how much power you have left in your battery, plug it into an electronic device or use a voltmeter. 

Set your Multimeter to read volts. For testing an 18-volt battery, choose the 20-volt setting. This will give you a more accurate reading.

STEP 8: Carefully touch the probes to their respective terminals; ensure that you are not connecting them. Once they’re in place, read the voltage shown on your Multimeter with a reassuring look at its screen.

NOTE: If you don't have a multimeter, you can skip steps 7 and 8.

STEP 9: To get a battery back to life, first, plug in the AC adapter. Then touch the black wire (negative) and white or striped one (positive). Wait about 60 seconds before disconnecting them again. This will give your battery enough charge for you to start it up.

NOTE: When touching two wires, one hand must hold the positive wire and hold on to a negative wire.

STEP 10: Test your battery pack’s voltage to make sure it is working as expected. If the voltage doesn’t rise, stop this process at that moment because continuing the process can damage your battery.

STEP 11: If you still only get a red flashing light and your battery won’t charge. Try boosting the voltage of the charger to between 10-14 volts. When you increased the battery from 11 to 14 volts, it began charging again.

STEP 12: With the charger plugged in, you will wait for it to recognize your battery. Pressing “pulse” on the battery and testing power until you have a green light is all that’s left.

STEP 13: With those as mentioned above few simple steps, you can fix a drill battery, get your battery back up to full power, and keep it that way.
