12V 9AH UPS Replacement Battery

This 12V 9AH sealed lead-acid battery replaces the original 7AH unit in APC Back-UPS RS 800VA systems. It uses AGM technology and T2 terminals for a direct fit. The higher capacity provides extended runtime for connected equipment during power interruptions. It is built for maintenance-free operation in any orientation.

9AH capacity and 4 to 7 year design life

The 9AH rating delivers more reserve energy than the standard 7AH battery, giving connected loads additional minutes of backup time. Expected service life spans 4 to 7 years under typical float conditions. The sealed AGM construction prevents electrolyte leakage and recombines over 90 percent of generated gas. Capacity will gradually decline as the battery ages toward the end of its design life.

Sealed AGM construction with T2 terminals

The absorptive glass mat design keeps the electrolyte immobilized, allowing safe use in any position and meeting non-spillable transport requirements. T2 terminals match the original connector layout for tool-free installation. Dimensions are 5.94in length, 2.56in width, and 3.72in height with a weight of 13.16lbs. A 24-month warranty covers defects in materials and workmanship.

Questions about this item

Will the 12V 9AH battery with T2 terminals fit the same slot as the original 7AH unit in my APC Back-UPS RS 800VA?

Yes, the 5.94in length, 2.56in width and 3.72in height match the standard form factor for this UPS, and the T2 terminals connect directly to the existing leads.

How can I confirm the AGM battery is charging correctly after installation?

The UPS will run a self-test on power-up; a solid green status light and normal runtime during a brief mains interruption show the 9AH pack is accepting charge and delivering power.

Does the package include mounting hardware or cables, or must I reuse the old ones?

Only the sealed 12V 9AH battery with T2 terminals is supplied; you reuse the existing cables and brackets from the previous 7AH module.
