How can I extend the life of my SigmasTek ST Series sealed lead acid battery while it is in storage?

In general, it is not recommended to leave sealed lead acid batteries in storage while in a discharged or partially charged state. Sealed lead acid batteries self-discharge about 3% every month and if they are not recharged periodically, you may not be able to recover its fully capacity.

To help extend the life of your SigmasTek ST Series battery, store your battery in a cool and dry place at 25°C (77°F).

A freshening charge for your SigmasTek ST Series battery is recommended at six months if stored at 25°C (77°F). For higher temperatures, the time interval will be shorter.
