How to Charge a Drill Battery Without a Charger 5 Easy Ways

Many people keep a charger plugged into their drill battery. But what happens when you need the charger and the power goes out? This post will provide step-by-step instructions on how to charge a drill battery without a charger!

How to Charge a Drill Battery Without a Charger

We gathered five easy ways to charge a drill battery without a charger for you to use. Some of these methods are fast and efficient, others take a little more time but could save the day when you need to get back to work now.

Here they are:

1) Using a Laptop Charger

A laptop charger can charge the drill battery in about an hour or two. It’s not that efficient, but it will do if you need a quick fix. You’ll have to open up your drill and remove the old battery from its holder, then attach the negative terminal on your new battery with some electrical tape to the negative terminal of your drill’s battery holder.

Then plug in your laptop charger and turn on the power. It will start charging immediately, but it won’t stop until you unplug it from both sources (the wall outlet as well as from your drill).

Be careful not to overcharge! Your battery might explode or leak acid all over if left plugged into a computer for too long without supervision. It is also very important that once the charge is complete, disconnect everything right away – otherwise, there could be damage done to both batteries.

2) Using a Charger for Batteries Other than the One You Have

You can just plug in any charger that fits your battery size. This way, you’re sure to get some juice into it even if your drill’s original battery is completely flat.

The downside of this method is that most chargers available nowadays are automatic or semi-automatic (that means they stop charging once the batteries are full).

Also, make sure you don’t leave an old and almost dead battery on one of these types of chargers because there could be damage done to both batteries if left plugged in too long without supervision!

3) Using a Portable Power Bank

This is better than using an old or almost dead charger since these power banks are designed to charge batteries that have run out of juice. However, the downside here could be the time needed for charging (it might take up to 24 hours) and because you can’t use your drill while it’s plugged in.

Unless the power bank has USB support so you can plug in both battery and drill simultaneously.

The other thing worth mentioning about this method is that even if the portable rechargeable battery pack doesn’t supply enough current, then don’t worry – at least you tried! You’ll still end up with one fully charged spare battery for your trusty cordless tool. Just remember not to leave the batteries on the power bank for too long because it could damage both.

4) Using the Power Outlet in Your Car

The drill battery is compatible with most cars’ power outlets. So if you’re driving, just plug it in to any 12V socket, and there you go – your batteries are fully charged!

This method works best for those who travel or work outside their homes on different sites where there aren’t always readily available power sources to charge up the drill’s batteries.

And unlike charging through USB, this way will not drain down both battery packs (if left plugged in for too long), so that means no damage done whatsoever.

Just make sure that this method won’t overcharge either by leaving everything plugged in overnight, though. 

Otherwise, it could cause problems like leakage from old batteries as well as damage to your drill.

The main downside of this method is that you need access to a car in order for it to work. Not all drills come with 12V batteries, so if yours doesn’t then don’t worry – read on and we’ll get into the last battery charging option below!

5) Using a Portable Power Source like an Anker Battery Charger

​This is perhaps the best and most efficient way to charge your drill batteries. We recommend this one especially for those who often work in remote areas where there isn’t constant access to power outlets or USBs, such as on construction sites!

These portable chargers look just like regular rechargeable battery packs that you can hold in your hands but instead of charging up smartphones, they’re designed specifically to charge different types of cordless tool batteries, from drills to blowers.

They usually have several slots inside them so you could put more than one type of battery at a time while it’s being charged (some even come with interchangeable plates). 

The other good thing about these kinds of chargers is that most of them come with smart technology that will automatically stop charging once the battery is full. That means you can leave it plugged in all day without worrying about overcharging or damage to your batteries.
