What it is

The BatteryJack 12V 5AH Recessed UPS Replacement Battery is a sealed, maintenance-free AGM unit built as a 100% OEM-compatible spare for uninterruptible power supplies. It arrives new and ready to install in compatible APC, Belkin, CyberPower, CSB and Best Technologies Patriot models listed by the supplier.

Who it suits

This battery fits owners of the listed APC Back-UPS Office and BF series units, Belkin Pro and Regulator Pro models, CyberPower Power99 units, and the named CSB and Patriot UPS devices that require a 12V 5AH recessed cell. Buyers whose UPS is not on the compatibility list or who need a different voltage or capacity should look at another part.

Deciding specification

The recessed form factor measures 5.51 inches long, 1.89 inches wide and 4.0 inches high, so the unit must physically match the battery cavity in your UPS. Verify those dimensions against the original battery before ordering to ensure a proper fit.
