The SigmasTek SP12-22HR battery is a 12V 22Ah rechargeable sealed lead acid (SLA) battery from the SigmasTek HR Series with an absorbent glass mat (AGM) design.
Designed with a safety vent that releases gas to prevent excessive internal pressure buildup, SLA batteries offer many benefits as they are low maintenance, leakproof / spillproof, reliable, and position insensitive (they can operate in any orientation).
The SigmasTek HR Series are multi-functional for both cycle and standby use, and they have a life expectancy of 3-5 years in standby use.
Batteries from the HR Series are also capable of providing long cycle life performance and are designed specifically for high-rate UPS discharge applications where higher power output is required over a short period of time.
The SigmasTek SP12-22HR battery typically comes with the NB Type Terminal but you may want to confirm that before purchasing. If you need a different terminal type than what’s available, adapters may be an option.

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