PowerWarehouse LEADACIDSLA12-15 replacement battery

This 12-volt 15-ampere-hour sealed lead-acid unit replaces the RBC12 cartridge in APC SU2200RM3U uninterruptible power supplies. It is built for server-room administrators who need a drop-in power-protection refresh without reconfiguring the rack. The maintenance-free chemistry eliminates electrolyte checks and suits continuous float service.

Thermals noise and power draw in normal use

The valve-regulated design runs silently with no moving parts and emits negligible heat during standby float charging. Self-discharge stays low so the UPS draws only the trickle current needed to maintain full capacity. No active cooling is required inside the cabinet.
