- Cordless drill battery
- Safety glasses
- Soldering iron
- Wire cutters
- Wire strippers
To rebuild a cordless drill battery, you’ll need these essential materials: safety glasses, a screwdriver, a soldering iron, solder, wire cutters, wire strippers, and a multimeter.
Dismantling the Battery
To begin the process of rebuilding a drill battery, the battery must first be dismantled. Here’s how:
- Remove the Battery Cover – First, unscrew or unclip the battery cover and set aside.
- Unplug the Wires – Next, carefully unplug the wires from the battery terminals.
- Remove the Cells – Once the wires are disconnected, use a flat head screwdriver to gently pry the cells away from the battery housing.
- Clean the Terminals – Finally, use a cloth and some rubbing alcohol to clean the terminals and the interior of the battery housing.
Once the battery is dismantled, you can begin to rebuild it. This guide will help you understand how to fix a drill battery and bring your drill back to life.
Cleaning the Battery
The battery must be cleaned before it can be put back together. To do this, first use a damp cloth to wipe away any dirt and debris. Be sure to clean any contacts and ports, as these are crucial for the proper functioning of the battery.
Use a small brush to scrub off any corrosion that may have built up over time. If the corrosion is particularly stubborn, you may need to use a stronger cleaning agent, such as vinegar or baking soda. Once the corrosion has been removed, use a dry cloth to wipe away any residue.
Finally, use a cotton swab to apply a thin layer of electrical contact cleaner to all the contacts and ports. This will help ensure that the battery continues to function correctly.
Once all the contacts and ports have been cleaned, the battery can be reassembled.
Testing the Battery
Before reassembling the drill battery, it is important to test it. This will ensure that the battery is working properly and will help to identify any issues that need to be addressed.
To test the battery, you will need a multimeter. Set the multimeter to the voltage setting and connect the leads to the battery terminals. The voltage should be within the range specified in the drill battery’s manual. If the voltage is outside of the acceptable range, the battery needs to be replaced.
Once the voltage has been checked, the multimeter should be set to the Ohms setting. Connect the leads to the battery terminals and the resistance should be within the range specified in the drill battery’s manual. If the resistance is outside of the acceptable range, the battery should be replaced.
Once the battery passes both tests, it is ready to be reassembled and reinstalled in the drill.
Replacing the Battery Cells
- Unscrew the case of the drill battery and remove the old cells, being careful not to cause any physical damage.
- Check the voltage of the old cells and purchase new replacement cells with the same voltage.
- Insert the new cells into the drill battery, taking care to ensure they are properly connected.
- Screw the case of the drill battery back together.
Test the drill battery to ensure the new cells are working properly.
Testing the New Cells
- Connect the new cells to the drill battery.
- Charge the drill battery for at least four hours.
- Check the voltage of the drill battery by setting the multimeter to 20V and connect the red probe to the positive post and the black probe to the negative post.
- Compare the voltage reading with the voltage rating of your drill battery. The voltage should be within 5% of the rating.
- Test the drill battery for performance by drilling into a piece of wood. If the battery is functioning correctly, the drill should be able to penetrate the wood.
Reassembling the Battery
Before reassembling the battery, make sure that all the components are clean and in good condition.
Step 1: Place the battery cells in their respective slots. Secure them using the screws provided.
Step 2: Connect the positive and negative terminals of the battery cells.
Step 3: Connect the battery terminals to the main circuit board.
Step 4: Connect the battery wires to the circuit board.
Step 5: Place the battery cover and secure it with the screws.
Step 6: Connect the battery to the charger and charge it until it is fully charged.
Step 7: Disconnect the battery from the charger.
Step 8: Test the battery by connecting it to the drill and turning it on.

Testing the Reassembled Battery
Before considering your drill battery rebuilt, it is important to test it. To do so, plug it into your drill or any other compatible device and see if it powers up. If it does, it is a sign that you have successfully reassembled the battery and it works.
If the drill battery does not power up, you may have to check individual parts. To do this, use a multimeter to measure the voltage of each cell. The voltage of a cell should be between 1.2V and 2V.
You can also check the wiring of the battery. Make sure that none of the wires have come undone or broken. Check the connections between the cells and the cables to make sure they are secure.
If everything seems in order, try charging the battery. If it charges successfully and powers up, then you have successfully rebuilt your drill battery.
Congratulations! You have successfully rebuilt your drill battery. Be sure to take care of it to make sure it lasts a long time.
Frequently Asked Questions
What kind of tools do I need to rebuild a drill battery?
Rebuilding a drill battery requires some basic tools and supplies. You will need:
