What this battery replaces

This 12 V 3.3 Ah sealed lead-acid unit is a direct drop-in for UPS cartridges that specify the same voltage and capacity. It suits installers who need a maintenance-free AGM block for backup power in security, telecom or emergency-lighting systems.

Capacity and terminal spacing decide fit

The 3.3 Ah rating and 1.6 inch terminal pitch are the two figures that determine whether the cell will sit and connect correctly inside the target UPS. Verify both numbers against the original cartridge before ordering.

Fits listed APC and CyberPower models

The battery slots into APC BACK-UPS ES 325, 350 and 350G families as well as CyberPower CPS 300, 320 and 325 SL units, replacing RBC35 and RBC47 cartridges. It requires no extra wiring or mounting hardware beyond what the host UPS already provides.

Questions about this item

What does the 3.3Ah capacity mean for my UPS runtime?

The 3.3Ah rating indicates the battery can deliver 3.3 amps for one hour under standard test conditions; actual UPS runtime depends on the connected load and the UPS unit's own efficiency.

How do the F1 terminals and 1.6-inch spacing affect compatibility?

This battery uses standard F1 faston tabs spaced 1.6 inches apart, matching the original APC RBC35 cartridge and listed CyberPower models so it plugs straight in without adapters.

Will the 5.28 x 2.64 x 2.4-inch case fit my BE350G battery compartment?

Yes, the case measures 5.28 inches long, 2.64 inches wide and 2.4 inches high, which matches the factory dimensions for the APC BE350G and the other listed UPS models.
