How to Disassemble a Makita Battery
- 1). Place the battery pack with the contacts facing upward on a work area. Install a chisel tip onto a soldering iron. Plug the iron in and let it heat up.
- 2). Push down gently with the iron and work around the entire perimeter of the top of the battery pack so that the tip cuts, or melts, through the plastic case without damaging the batteries or components inside the case.
- 3). Grasp the battery pack near the contacts at the top and pull it straight upward to separate the two halves. Pull firmly but gently to separate the batteries from the adhesive insulator sheet that holds the them into place in the bottom of the battery pack casing. Place the bottom portion of the battery pack aside.
- 4). Remove the batteries from the upper portion of the battery pack by heating up the soldered connectors with the soldering iron. Pull the battery away from the pack to release it from the adhesive insulating sheet. Remove all batteries (there are a total of 12) in the same fashion if necessary.
- 5). Unplug the soldering iron and let it cool.
