This procedure requires removing the battery to disconnect it. Use care to avoid bending, twisting, or puncturing it—a charged lithium-ion battery can be very dangerous if accidentally punctured. If your battery looks puffy or swollen, take extra precautions.
Don't continue to use a damaged battery, as doing so is a potential safety hazard. If in doubt, replace it with a new battery.
