Replacement UPS Battery for APC Models

The BTI APCRBC124-SLA124 is a new replacement battery designed for specific APC Back-UPS and Smart-UPS units. It fits models including BR1200G-FR, BR1200GI, BR1300G, BR1500G, BR1500G-FR, BR1500GI, SMC1000-2U and SMC1000I-2U. This unit restores backup power capability for compatible UPS systems.

Capacity and Runtime Headroom

The battery pack contains four sealed lead-acid cells rated at 12V 9Ah. It delivers maintenance-free operation for typical desktop and network loads during outages. Runtime decreases as connected load approaches the UPS maximum rated capacity. Extended outages or heavy peripheral draws will exhaust the reserve faster.

Upgrade Context and Compatibility Limits

This product replaces the original APCRBC124 cartridge when its runtime degrades. It is not suitable for UPS units outside the listed APC model range. Buyers needing higher voltage configurations or lithium chemistry alternatives should verify their UPS specifications before purchase.

Questions about this item

Will the 12 V 9 Ah 4-cell pack fit my APC BR1200GI without rewiring?

It is a direct replacement for the APCRBC124 cartridge used in the BR1200GI and other listed APC models; the existing connectors match.

How can I confirm the new 12 V 9 Ah battery is holding charge after installation?

Run a self-test from the UPS front panel or management software; a pass indicates the 4-cell pack is delivering the expected voltage and runtime.

Does the 10.59 lb sealed lead-acid unit ship with mounting hardware or just the battery?

The package contains the complete 4-cell replacement cartridge only; no extra brackets, cables or tools are included.
