How Do You Revive A Cordless Drill Battery?

Reconnecting a drill battery is not as easy as it sounds.

It requires some knowledge and experience to get the job done right, but if you follow these simple steps, you will be able to revive your cordless power tool in no time!

Step 1: The first thing that we need to do is remove all of the dead batteries from our drill so that they are completely disconnected.

This can easily be accomplished by removing the two screws on top of each side of the handle.

Once this has been completed, we should then turn off the power drop switch located at the back of the tool.

Step 2: Next, we must make sure that there is nothing connected to any other part of the drill except for the motor itself.

If anything else is attached, such as an extension or bit holder, we may damage them when trying to reconnect the healthy battery pack.

We also want to ensure that none of the wires have come loose during disassembly.

Step 3: Lastly, we should take note of how many cells are inside the battery pack.

Some packs contain more than one cell while others only hold one.

Knowing which type of pack we have before attempting to connect it will help us determine what kind of battery charger we need to use.

Now that everything is ready, let’s start connecting the new battery pack into place.

  • First, we’ll insert the positive end of the battery pack into the negative terminal of the old battery.
  • Then, we’ll slide the positive end down until it reaches the bottom of the hole where the screw was removed earlier.
  • After doing this, we’ll tighten the screw again to secure the connection.
  • The last step is to plug the substantial power cable into the wall outlet and turn on the drill. When the light turns green, we know that the battery is fully charged.

How do I know if my cordless drill battery is bad?

That being said, here are three signs that indicate that your drill battery might be dying:

1) Your drill doesn’t seem to run properly.

It could be because the battery isn’t charging correctly.

Or maybe the problem lies somewhere else. Either way, it’s best to replace the battery immediately.

2) There seems to be something wrong with the motor.

You may notice a grinding sound coming from the drill.

In addition, the motor may feel sluggish when turning. These symptoms mean that the motor is probably damaged.

3) The LED lights aren’t working.

They’re supposed to illuminate whenever the drill is powered on.

However, if yours stops lighting up altogether, it means that the battery is faulty.

In order to avoid having to buy another battery, try reconditioning your current one instead.

Reconnection Instructions:

  • To begin, remove all screws holding the battery in place.
  • Then, disconnect the two leads of the battery by gently pulling each wire away from the battery case.
  • Next, you can reattach the battery using the same procedure used to install the original battery.
  • Simply push the positive lead back into the negative side of the battery and then attach the remaining parts of the battery pack.

Once done, simply charge the battery like normal.

Reconditioning Battery To Remove Crystallisation And Improve Performance

When drilling holes through concrete, wood, metal, etc., you often find yourself needing to drill multiple holes at once.

This requires a lot of torque to get the job done right.

However, over time, the batteries tend to lose their ability to deliver enough voltage to keep the motors running smoothly.

As a result, they become less efficient and eventually stop delivering adequate amounts of energy.

This causes the drills to slow down considerably.

Fortunately, there are ways to fix these issues without replacing the entire unit.

In fact, some people even recommend trying out different types of rechargeable battery for better performance.

Here are 3 tips to improve the life span of your drill batteries:

1) Use high-quality replacement batteries.

If possible, choose ones made specifically for your model of drill.

They should also come with an instruction manual so that you don’t make any mistakes while installing them.

Also, look for modern batteries that have been tested under extreme conditions, such as those found in construction sites or other places where heavy duty tools are needed.

2) Keep the battery cool.

Batteries work much more efficiently when kept at room temperature.

If you need to store them outside during hot weather, wrap them in plastic bags before placing them inside a cooler.

Alternatively, you can use ice packs to help maintain proper temperatures.

3) Don’t leave the batteries unattended.

It’s important not to let the batteries sit idle for too long because this will cause crystallization to occur within the cells.

As a result, the capacity of the smart batteries decreases significantly.

Instead, always take care of your batteries properly.

For example, never allow them to freeze, since doing so could damage the internal components.

Also, do not expose them to direct sunlight, which would increase heat levels.

Instead, put them on a shelf or somewhere else where it won’t be exposed to harsh elements.

You may want to consider a replacement battery if you notice signs of deterioration after prolonged usage.

However, if you’re looking for a way to extend the lifespan of your existing batteries, you might want to give reconditioning a shot first.

  1. The process involves removing old batteries and replacing them with fresh ones.
  2. Once installed, you’ll see significant improvements in terms of effective power output.
  3. In addition, you’ll no longer experience problems related to overheating or freezing.

You can learn how to perform this procedure here.

Reconditioning A Li-ion Drill Battery

Reconditioning a li-ion drill battery is an essential part of maintaining your equipment.

It’s also a necessary step if you want to get the most out of your tools.

If you’re looking to recondition a dead li-ion battery drill, then you’ll need to follow these steps.

Step 1: Remove the old battery

Step 2: Clean the contacts

Step 3: Recharge the battery

Step 4: Install the new battery

Step 5: Test the tool

Step 6: Replace any worn parts

Step 7: Check the battery charger

Step 8: Charge the battery

Step 9: Store the battery

Step 10: Use the battery

Step 11: Dispose of the used battery

However, over time, the batteries tend to lose their ability to deliver enough voltage to keep the motors running smoothly.

As a result, they become less efficient and eventually stop delivering adequate amounts of energy.

This causes the drills to slow down considerably.

Conclusion:

The reconditioning process for a battery is normally carried out over a long period of time.

The maximum amount of discharge that a battery can withstand is called the “deep discharge” condition.

A battery reconditioner will take a discharged battery in the state where a constant current is flowing through the battery to bring it back to this condition.
