Direct APC BP650SX107 Replacement

This PowerWarehouse 12 V lead-acid battery cartridge matches the APC BP650SX107 unit exactly. The two-pack supplies both cells required for a complete refresh. Offices and small server rooms use it to restore runtime on aging UPS hardware without sourcing original parts. Compatibility is guaranteed by the manufacturer for the listed model.

Tool-free cartridge swap

Installation consists of opening the UPS front door, unplugging the old cartridge and sliding the new one into the same rails. No soldering or cable assembly is needed. The most common issue is forgetting to recycle the spent cells, which are classified as hazardous waste. A second pitfall is delaying replacement until the UPS self-test fails, leaving equipment unprotected during a power event.

Questions about this item

How do I confirm the 12V 2XRBC4SLA420 batteries are working correctly after installation?

The UPS should power on normally, show a full charge indicator, and pass its self-test cycle without reporting a battery fault.

What comes in the 2XRBC4SLA420 pack and what must I buy separately?

The pack includes two 12V lead-acid battery cartridges; no cables, mounting hardware, or UPS unit are included.
