Direct UPS replacement

The American Battery RBC43 is a maintenance-free sealed lead-acid cartridge designed as a drop-in replacement for compatible APC UPS units. It arrives new and ready to install with the included tray, cables, connectors, fuses and guides.

480 VAh capacity with 3–5 year life

The cartridge delivers 480 VAh at 12 V DC, providing runtime for typical rack-mount UPS loads in the 2200–3000 range. Expected service life spans three to five years, after which capacity will decline and a fresh cartridge will be needed.

Sealed design limits heat and noise

The enclosed, hot-swappable construction keeps electrolyte contained and requires no liquid maintenance. In normal operation the battery runs silently and adds minimal thermal load to the UPS chassis, drawing power only during charge cycles.

Questions about this item

Will the RBC43 cartridge fit my SUA3000RM2U without rewiring the rack tray?

Yes — the RBC43 is listed as compatible with the SUA3000RM2U and ships as an enclosed cartridge with its own metal tray, so it slides into the existing battery bay using the original connectors.

How can I confirm the 480 VAh capacity is delivering full runtime after installation?

Run a self-test from the UPS front panel or management software; a healthy RBC43 should report the expected runtime for a 480 VAh pack at your current load percentage.

Does the box include the fuses and connectors needed for a hot-swap replacement?

The package contains the replacement battery cartridge, cables, connectors, fuses, metal tray, installation guide and recycling guide — everything required for a hot-swappable swap.
