How to Rebuild a Battery Pack
It can be a difficult task trying find a replacement battery pack for all of your cordless tools and other appliances. Instead of going through the trouble of hunting down replacement packs, it would be more efficient to rebuild the pack yourself.
Things that you would need:
- Wire brush
- Screw driver
- Ni-Cad or Ni-Mh battery cells
- Epoxy adhesive
Instructions:
- Examine the battery pack and check for any screws. If there are screws located of the pack, uses a screwdriver to disassemble them.
- Use a soldering gun with a chisel tip located on the end to separate the battery pack in two pieces so that you can get to the batteries.
- Take notes on the way that the batteries are connected and how the cells are arranged. If you have trouble getting the batteries out, try warming it up to make it easier.
- Disconnect each of the batteries and place them aside from the pack.
- Use a wire brush to clean the connections that are still in the pack and clean all the ends of the wires. Use the notes that you took before you took the battery out to set the new battery cells in back in place they were before. Once the batteries are in place, solder the connections.
- Put the screws back into the battery pack or use epoxy adhesive if you have a one-piece unit. Your battery pack should be ready to use and is recharged.
