So to maintain the maximum non-recoverable capacity. Does that mean it is best to leave the battery slight charged in the fridge, and take it out for a full charge and discharge every 3 month or so? jake > There are two factors to consider during storage: > > A battery will self-discharge at about the rates shown > below.
