Compatible UPS Battery Cartridge

This replacement cartridge delivers two 12 volt lead acid batteries rated at 43 ampere hours each. It is built to fit the APC SMT2200RM2U uninterruptible power supply and restores backup runtime for servers and network equipment.

Thermal and Power Behaviour

The sealed lead acid cells operate without fans so they add no audible noise to the rack environment. Normal float charging draws only a modest trickle current and the batteries remain at ambient temperature during standby.

Questions about this item

How do I install the 12 V PowerWarehouse cartridge #43 into my APC SMT2200RM2U and what step is often missed?

Power off the UPS, remove the front panel, slide out the old cartridge, insert the new 2XRBC43SLA434 pack, then secure the retaining bracket before closing the panel — skipping the bracket leaves the batteries loose.

What maintenance will the 2-pack of 12 V 43 Ah lead-acid batteries need and when should I replace them?

Keep the UPS in a cool, ventilated rack, run a self-test monthly, and plan replacement after 3 to 5 years or when the APC management card reports a battery fault or reduced runtime.
