Direct UPS Replacement

This 12V 3.3Ah sealed lead-acid battery uses AGM technology to fit RBC35 and RBC47 cartridges. It serves as a 100% OEM replacement for APC Back-UPS ES models such as BE325-FR, BE350, BE350C, BE350ES, BE350G and BE350U. The unit also matches Cyber Power CPS300SL, CPS320SL, CPS325SL and Conext CNB325 units. It arrives new and ready for maintenance-free operation.

Sustained Backup Performance

Advanced AGM chemistry delivers stable voltage during extended discharge cycles rather than only brief surges. The maintenance-free design prevents electrolyte loss over the expected 4 to 7 year service life. Compact dimensions of 5.28 by 2.64 by 2.4 inches with a 1.6 inch terminal spacing allow reliable installation in tight UPS enclosures without ventilation requirements.

Critical Fit Specification

The 1.6 inch distance between terminals determines whether this battery connects correctly to your UPS cartridge. Verify this spacing against the original unit before ordering. Buyers whose equipment uses a different terminal pitch or a higher amp-hour rating will need an alternative power source.
