12 V 9 Ah UPS Battery

This sealed lead-acid battery uses AGM technology to deliver 12 volts and 9 ampere-hours for uninterruptible power supplies. It measures 5.94 in by 2.56 in by 3.72 in and weighs 13.16 lbs. The maintenance-free design is rated for four to seven years of expected life. It arrives new and ready to install.

T2 Terminal Fit and Warranty

Builders whose UPS requires a T2 terminal and a 12 V 9 Ah form factor can use this as a direct OEM replacement. Buyers who need a different terminal style, a higher capacity or a lithium chemistry should look elsewhere. The unit carries a 24-month warranty and a 30-day money-back guarantee.

Sustained Discharge Behaviour

Under continuous load the AGM construction recombines over 90 percent of generated gas, keeping voltage stable without electrolyte loss. The sealed, non-spillable case allows operation in any orientation during long runtime events. No watering or periodic maintenance is required throughout the service interval.
