What battery reconditioning means

Battery reconditioning is a broad label for processes intended to restore some lost performance. The appropriate process depends on chemistry, condition and failure mode. It is not a guarantee that a failed battery can be made safe or reliable again.

Start with diagnosis

Before attempting restoration, identify the battery type, inspect for physical damage, and follow the battery and charger manufacturers’ instructions. Swollen, leaking, cracked, frozen or otherwise damaged batteries should not be treated as DIY recovery candidates.
