The SigmasTek SP Series are multi-functional for both cycle and standby use, and they have a life expectancy of 3-5 years in standby use.

How can I extend the life of my SigmasTek SP 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 SP Series battery, store your battery in a cool and dry place at 25°C (77°F).

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

What does it mean if my SigmasTek battery is swollen?

Immediately remove and discontinue use of any sealed lead acid battery if it is bulging or bloated as it means it has become damaged.

Sealed lead acid batteries can become damaged and swollen if they are overcharged or short-circuited. This can happen if the battery charger is providing too much current, such as using a 24V charger to charge a 12V battery.

Be sure to take care in properly charging your SigmasTek battery by using a good quality charger that is fully compatible with your battery.
