UPS Battery for Backup Systems

The BatteryJack UB1280 is a 12V 9AH sealed lead-acid unit built as a direct replacement for uninterruptible power supplies. It uses AGM technology to deliver maintenance-free operation in a leak-free case. The battery suits server rooms, network closets and home offices that need reliable runtime during outages.

Fits Standard UPS Chassis

Measuring 5.94in long, 2.56in wide and 3.72in high, the brick slides into existing battery trays without modification. T2 terminals connect to the UPS wiring harness using the original cables. At 13.16lbs it adds no extra structural load, and the non-spillable design allows mounting in any orientation the cabinet requires.

Sustained Discharge Reliability

The AGM glass-mat separator holds electrolyte against the plates for steady voltage through long discharge cycles. Gas recombination exceeds 90 percent, reducing internal pressure and extending service life toward the 4-7 year expectation. A 24-month warranty covers the unit under continuous float or cyclic use.
