Exact APC Fit

The RBC35-SLA35-BTI is a sealed lead-acid replacement battery built for APC Back-UPS ES 350 units. It serves owners of models BE350C, BE350G, BE350R, BE350T and BE350U who need a drop-in power source. Buyers with larger UPS frames or different connector layouts will not be able to use this pack.

Sealed Lead-Acid Build

The battery uses a maintenance-free lead-acid chemistry housed in a black enclosure that weighs 3.5 lbs. Its sealed design prevents leaks and allows installation in any orientation the UPS chassis requires. No external wiring harnesses or adapters are included, so the original connectors must be reused.

Restores Original Runtime

This unit replaces a depleted OEM cartridge and meets or exceeds the manufacturer’s original specifications. The swap returns the UPS to its factory backup time for the supported 350 VA models. If the host unit has developed charger faults or the load has grown beyond the original rating, a fresh cell alone will not solve the problem.
