The rate at which battery capacity is lost during storage is called the self-discharge rate. The battery self discharge rate, also known as the charge retention capacity, refers to the ability of the battery to maintain the stored capacity under certain conditions when the battery is in an open circuit state.
A lead acid battery left in storage at moderate temperatures has an estimated self-discharge rate of 5% per month. This rate increases as temperatures rise and as the risk of sulfation goes up. Sulfating: This is a buildup of lead sulfate crystals and it occurs when a lead acid battery is left sitting without a full charge.
By discharging a lead acid battery to below the manufacturer's stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed. This causes permanent damage to those cells and prevents the battery from ever being recharged.
