Cordless Drill Batteries (Your Queries Answered)

Do you use a cordless drill? While they can be great for convenience, there is that issue with the batteries at times. You might come across situations where you have to replace the battery and get a new one. You will need to find the perfect cordless drill batteries for your particular need in those scenarios.

Now, to help you out with that, I have got all the information covered in one place. You will get everything you need to know to get a cordless drill battery. Let’s get going with the whole thing then.

Can I use a higher voltage battery in my drill?

This is a confusion many people go through regarding the drill battery. In simple words, the answer is no; you can’t use a higher voltage battery in your drill. Most electronic items use a battery for a preferred voltage. Using the wrong voltage for them can mess up the whole thing and may even damage the tool.

Especially when you are using a higher voltage battery, it can damage the drill entirely beyond any kind of repair. So, even if you can install or find batteries with a higher voltage, you shouldn’t use them in your drill at any cost.

12V vs. 18V vs. 20V battery-powered drill difference

Imagine you decide to get a drill; now the question comes of which one to pick based on voltage? How do you differentiate between 12v, 18v, and 20v? Let’s take a quick look at the differences between them, and you will know which one works out for your situation. I will go through some factors that help you see the difference between them.

  • Power

The core difference between these voltages is their power. A higher voltage means more power. So, when you need a lot of power in your drilling work, 20V is the choice. If you get into a medium drilling job, then 18v can be a good pick. As for the lightweight drilling, 12v is the way to go.

  • Running time

Usually, the battery’s voltage doesn’t have an impact on the running time. It’s the current load draw and the battery condition that determines the runtime.

So, let’s say you have a 12V battery that’s fresh compared to an 18V battery with worn-out condition. Even in that scenario, the 12V battery will run longer than the 18V.

  • Weight

There is also a clear difference between the weight of the batteries based on their voltage. 12V batteries will be much more lightweight compared to 20V batteries. Because of this, 12V batteries are much more suited to indoor conditions. Whereas 20V batteries work out better in outdoor or spacious environments.

  • Charging time

Unlike the runtime, there is a difference between the charging time for each of the batteries. A lower voltage battery charges quicker because it has less capacity and load. So, considering that, a 12V battery will charge much quicker than a 20V battery.

  • Cost

It’s pretty easy; the more power it holds, the pricier it gets. According to that, a 20V battery or an 18V battery will cost much more than a 12V battery.

  • Job site requirement

A higher voltage also means a higher torque. Torque has a lot of impact on the particular projects or jobs you are doing. So, if you have to drill through tough objects and heavy-duty drilling, you will need a battery with a higher voltage, like 20v. As for some indoor drilling purposes, you can make do with a 12V battery without any issues at all.

Can I put an 18v battery on a 12v drill?

As I said earlier, it’s better not to use the wrong voltage battery on a particular drill. Yes, you may use a lower voltage battery in a higher voltage capable drill. But never use a higher voltage battery on a lower voltage drill at any cost. It can severely damage the motor of the drill and make it unusable.

Can I use an 18v adapter for 12v?

Here’s the thing, whenever you use a higher voltage adapter for a lower voltage battery, you can easily burn the battery. So, I wouldn’t recommend using an 18V adapter for a 12V battery.

Can you use a 24v battery on an 18v drill?

No, you can’t use a 24v battery on an 18v drill. Using a higher voltage battery on the lower voltage drill can potentially damage your drill’s motor.

Can you use a 12v battery in an 18v drill?

Yes, it’s possible to use a lower voltage battery on a higher voltage capable drill. So, you can use a 12v battery in your 18v drill. However, it can’t put out the kind of power you would expect to get on an 18V drill.

Are cordless drill batteries interchangeable?

Cordless drill batteries are only interchangeable between the same manufacturers. But if you are trying to run a battery from a different manufacturer on another drill, then it won’t work. Also, they are interchangeable if they are of the same voltage and similar in size.

How to Get the Most Out of Your Battery-Powered Cordless Tools?

Well, you might not know, but taking good care of your battery can easily help you extend the battery life. It makes the whole thing even more durable than you would expect it to be. So, let’s see how you can get the most out of your battery powered cordless tools –

  • Charging the battery correctly

One of the most common mistakes people make with rechargeable tools is that they don’t charge them properly. The best way to recharge your battery is when it has 70% battery remaining. If you follow this, you can ensure a longer battery life for sure.  

Also, ensure you are not removing the battery from charging before it gets to 100%. Don’t unplug the charger midway before it completes.

  • Using the tool regularly

Here’s the thing, when you leave out your cordless power tools that run on battery, you are risking it breaking down. You have to make sure that you use the tool regularly.

  • Keeping the battery dry and cool help

One of the key components of keeping your battery dry and cool is to ensure the proper storage method. Where you are keeping the battery has a lot to play with in keeping it dry and cool. You have to make sure it’s adequately covered.

  • Handle the battery carefully

Whenever you hold the battery, you have to make sure you are doing everything gently. Batteries can easily get damaged when you are not careful with them. So, make sure to be gentle with the whole thing.

Doing all these can help you get the most out of your battery-powered cordless tool. One key thing is that never leave the tool unused.

Are there any benefits of lower voltages in cordless tools?

Yes, you get some advantages from a lower voltage cordless tool. First of all, lower voltage tools will be much cheaper. Also, they are smaller, so they can fit in smaller places. Lastly, charging a lower voltage cordless tool is much quicker in comparison.

What does it mean when a battery has more volts? 

When a battery has more volts, it just means that it can put out more power. More volts just mean less current required to do a task. As a result, you can get more torque out of it without putting out too much current. Altogether, having more volts simply means a powerful battery.

Do higher voltage batteries last longer?

Yes, a higher voltage battery usually lasts a bit longer. Since higher voltage takes up less current, it also runs out slowly. Because of this reason, the batteries tend to last a lot longer than you would expect.

How long does a drill battery take to charge?

Well, I can’t give you a fixed number on that because different drill batteries take different duration for charging. Typically, it can take about 30 minutes to 4 or 5 hours to charge the drill battery. However, some ultrafast chargers out there take just about 10 minutes to charge a drill battery completely.

What does ah mean on battery drills?

Ah means Ampere hour. It’s the indication of the current your battery can put out. It mostly indicates the charge capacity. So, a higher ah means a higher charge capacity, and that means it will have a higher runtime.

Should I leave the battery in the drill?

Yes, it’s not a problem. You can keep the battery inside your drill all the time, and you won’t have any issues whatsoever. On the other hand, if you take it out, you have to think about properly storing it. So, I recommend keeping it inside the tool.

How to charge a power drill battery without a charger?

First of all, you will need to determine the battery’s voltage that you are dealing with. After that, you can move on to the process of charging a battery without using the charger. Here’s how you do it –

  • Remove the battery from your drill and then open it through unscrewing. You have to remove the whole cover of the battery and get the actual batteries inside.
  • Make sure to figure out the positive and negative end of the battery, following up with the covering.
  • Then, you have to get the power supply socket and install it inside the case. Also, make sure you have to solder the socket’s wires on the battery.
  • Once you have that socket installed on your battery, you can use a DC power supply or adapter to charge your battery.
  • Keep in mind that the power supply has a volt controller in it so that you can adjust the volt according to the voltage of your battery.
