Reviving a dead rechargeable battery can sometimes be achieved by a process called 'jump-starting.' Use a compatible charger and charge the battery slowly, ideally on a low voltage setting. If it's a NiMH or NiCd battery, you can also cycle the battery by fully discharging and then charging it a few times. Inspect for any damage before attempting revival. Safety first! If the battery shows signs of leakage, swelling, or overheating, do not attempt revival—replace it instead to avoid potential hazards.
