APC by Schneider Electric RBC26 Replacement Battery Cartridge
Overview
The RBC26 is a direct-replacement battery cartridge for compatible APC UPS systems. When runtime degrades or a battery fault alarm triggers, swapping in a factory-new RBC26 restores full rated runtime without replacing the entire UPS chassis — the practical choice for facilities running tight refresh cycles on infrastructure protection hardware. The RBC26 uses a sealed lead-acid chemistry, which requires no maintenance and is safe for installation in enclosed equipment rooms and wiring closets.
Compatibility
Verify compatibility against your specific UPS model number before ordering. The RBC26 is designed for select APC UPS systems within the APC by Schneider Electric product line. Cross-reference your UPS model number on the APC compatibility selector to confirm the RBC26 is the correct cartridge — using a mismatched RBC number will result in incorrect voltage or physical fitment. If you are unsure which RBC cartridge your unit requires, locate the model label on the rear of the UPS and match it against APC's published compatibility list.
Installation Notes
APC replacement battery cartridges are designed for hot-swap installation on supported models — no tools required and no UPS shutdown necessary on qualifying units. Confirm whether your UPS model supports hot-swap before proceeding; units that do not will require a controlled shutdown prior to battery replacement. Dispose of the spent lead-acid battery through a certified recycling channel — do not discard in general waste. Allow the replacement cartridge to charge fully before subjecting the UPS to a full-load runtime test.
