Pulling 18650 Batteries from Laptop Batteries
Assuming that you have a laptop battery that you are ready to tear into, lets talk about the precautions. You will first need to open the casing but you will need to be careful not to slice into the cells as this could cause a fire. When opening the casing use gloves and an utility knife to trace the seem. It may take several passes before the case is able to be opened.
After the casing is open and the cells are exposed, the wires and ribbon cable attached to the circuitry need to be cut with wire cutters. The cells inside the casing maybe glued or taped securely into the casing. You will need to use a flat blade screwdriver to pry them loose. Be careful not to crush the cells during this process.
After you have removed the cells then you can start to cut the cells apart from each other. Now that they are separated you will need just clean up the cell terminal by using needle nose pliers to roll off any remaining tab remnants.
