Replacement Battery for UPS Units

This 12 V 3.3 Ah sealed lead-acid battery replaces the HZS12-3.3 model in compatible uninterruptible power supplies. It uses AGM technology for maintenance-free operation and a compact design suited to backup applications.

Terminal Spacing Determines Fit

The distance between terminals measures 1.6 inches, which is the critical dimension for correct installation. Verify this spacing against your device before ordering to ensure a secure connection.

Capacity Handles Small UPS Loads

Rated at 3.3 Ah, the cell comfortably runs entry-level UPS units such as the BE325, BE350 and CPS325 series during short outages. Extended runtime or larger loads will exceed its capacity.

Questions about this item

What does the 3.3Ah rating mean for runtime in my UPS?

The 3.3Ah capacity indicates how much charge the battery stores; actual runtime depends on the load your UPS draws.

Which connector standard does the 1.6-inch terminal spacing match?

The 1.6-inch distance between terminals follows the common F2 faston standard used in many small UPS units.

Will the 5.28 x 2.64 x 2.4-inch case fit my APC BE350 battery compartment?

Those dimensions match the original RBC35 cartridge, so it fits the BE350 and listed compatible models.
