Direct Replacement Battery

This 12 V 3.3 Ah AGM battery is a direct replacement for the Long WP312 and compatible RBC cartridges. It uses sealed lead-acid technology with maintenance-free operation for UPS units, emergency lighting and security systems.

Suits Standard UPS Units

It fits common APC Back-UPS ES models such as BE325, BE350, BE350G and CyberPower CPS300SL, CPS325SL units. Buyers needing higher capacity than 3.3 Ah or a different terminal layout should look at other options.

Capacity and Runtime

The 3.3 Ah rating provides reliable backup for typical desktop UPS loads and alarm panels. Runtime decreases under heavier loads, so systems drawing more current will exhaust the reserve faster.

Questions about this item

Does the 1.6 inch terminal spacing match the Long WP312 battery I am replacing?

The terminal centres are 1.6 inches apart, which is the standard spacing for the Long WP312 form factor.

Will the 5.28 by 2.64 by 2.4 inch case fit inside my APC BE350 UPS chassis?

Those dimensions match the original RBC35 cartridge used in the BE350, so the battery slides into the same compartment.

How can I verify the 12 V 3.3 Ah rating after installation?

Measure the open-circuit voltage with a multimeter; a reading near 12 V confirms the rated output.
