The SigmasTek SPF12-40 battery is a 12V 40Ah rechargeable sealed lead acid (SLA) battery from the SigmasTek SPF Series featuring an absorbent glass mat (AGM) design and easily accessible front terminals.

Compared to top terminal batteries, the front terminals of batteries from the SigmasTek SPF Series simplify its installation, improve safety, and offer a smaller footprint per kilowatt, making it a cost-effective solution.

How can I extend the life of my SigmasTek SPF 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 SPF Series battery, store your battery in a cool and dry place at 25°C (77°F).
A freshening charge for your SigmasTek SPF Series battery is recommended at six months if stored at 25°C (77°F). For higher temperatures, the time interval will be shorter.
