Direct replacement for APC BE325 series UPS

This sealed lead-acid battery fits APC BE325, BE325R, BE325-CN and CNB325 units. It replaces OEM part RBC47 and restores backup power to those models. Installation follows the original form factor with no adapter required. The unit ships new and ready for immediate use.

12 V 3.5 Ah single-cell capacity

The 12 V 3.5 Ah rating supports typical desktop and networking loads during short outages. One cell keeps the internal resistance low for reliable starts. Runtime scales with attached load; heavier draws will exhaust the reserve faster. The chemistry tolerates float charging in continuous UPS duty.

Upgrade from a depleted or aged RBC47 pack

Swapping a worn pack restores the UPS to its original hold-up time. The jump is worth it when self-tests fail or runtime drops below useful levels. Buyers needing longer autonomy or higher wattage than the BE325 chassis provides will need a larger UPS instead.

Questions about this item

Will the RBC47-SLA47-BTI fit the APC BE325R I already own?

Yes, the battery is listed as compatible with the APC BE325R, BE325, BE325-CN and CNB325 models and replaces OEM number RBC47.

How can I verify the 12V 3.5A battery is working after installation?

Power on the UPS and confirm the status indicator shows a healthy charge; the unit should hold a load for the expected runtime during a brief self-test.

Does the package include the RBC47-SLA47-BTI battery only, or are cables and mounting hardware supplied?

The product is the replacement battery cartridge itself; any required cables or mounting brackets are reused from the original APC UPS.
