SP, SPG, HR and SPX Series batteries can be stored for up to 6 months at 25°C (77°F) and then a freshening charge is recommended. For higher temperatures the time interval will be shorter. For lower temperatures the time interval may be longer. 12 Volt batteries should never be allowed to self- discharge below 12.4 volts, 6 volt batteries should never be allowed to self-discharge below 6.2 volts. A refreshing charge is recommended before the battery in storage self-discharges past these levels.
