Compatible replacement for APC SU1400BX120

This PowerWarehouse LEADACIDSLA7-07 battery replaces the original RBC7 cartridge in the APC SU1400BX120 UPS. It uses a maintenance-free lead acid design that arrives ready to install without electrolyte handling. The unit restores backup runtime for connected servers and network gear when the original cells reach end of life.

Sustained discharge and thermal stability

Under continuous load the sealed lead acid chemistry delivers a steady voltage curve without the sharp drop-off seen in short bursts. Internal resistance remains stable during extended outages, letting the UPS maintain output until the low-voltage cutoff. The maintenance-free construction prevents electrolyte loss over repeated deep cycles, supporting reliable performance across the battery’s service life.

Questions about this item

How much heat or noise does the LEADACIDSLA7-07 produce during continuous operation?

The battery is a sealed lead-acid cartridge with no moving parts, so it generates no fan noise and minimal heat under normal UPS charging cycles.

What existing hardware is required for the RBC7 cartridge to function?

It must be installed inside a compatible APC Smart-UPS unit such as the SU1400BX120; the battery cannot operate on its own.
