Replacement Cartridge for BE325R and BE350S

This 12V 3.3AH sealed lead-acid cartridge fits the BE325R and international BE350S UPS models. It uses AGM chemistry for maintenance-free operation in backup power applications. The cartridge replaces original RBC35 and RBC47 battery packs directly.

AGM Build with 1.6-Inch Terminal Spacing

The battery measures 5.28 inches long, 2.64 inches wide and 2.4 inches high with terminals spaced 1.6 inches apart. This compact layout matches the original cartridge footprint so it slides into the UPS chassis without modification. Maintenance-free AGM construction eliminates fluid checks and allows any orientation mounting.

Ready-to-Install Pack for Immediate Swap

The cartridge ships fully charged and assembled so the UPS returns to service after a simple plug-in exchange. No cables, brackets or software are included because the original hardware is reused. Expected service life reaches 4-7 years under normal float conditions.

Questions about this item

What voltage and capacity does the 12V 3.3AH cartridge deliver to the UPS?

It supplies 12 volts at 3.3 amp-hours using sealed AGM chemistry, matching the original BE325R and BE350S specifications for runtime and charge acceptance.

Will the 5.28 by 2.64 by 2.4 inch case with 1.6 inch terminal spacing fit my BE325R battery compartment?

Yes, those exact dimensions and terminal pitch are designed to slide into the BE325R and international BE350S trays without modification.

How do I install the cartridge and which step do people skip?

Power off and unplug the UPS, open the battery door, disconnect the old leads noting polarity, connect red to positive and black to negative on the new cartridge, close the door, then power on — the step most often missed is verifying the polarity before tightening the terminals.
