PowerStar 12V 3.5AH SLA UPS Replacement Battery 2PK

SKU CH-1EEF-69RP3

Two-pack of 12 V 3.5 Ah sealed lead-acid batteries with 1.6 inch terminal spacing for UPS replacement

  • Maintenance-free AGM design eliminates fluid checks
  • 100 % OEM fit replaces RBC35 and CyberPower cartridges
  • 3 Ah capacity powers UPS emergency lighting and alarms
  • Compact 5.28 × 2.64 × 2.4 in footprint suits tight enclosures
  • 4 to 7 year expected service life under float conditions

Direct Replacement for APC and CyberPower Units

This pack contains two sealed lead-acid batteries built to fit the APC RBC35 and RBC47 cartridges used in Back-UPS ES 325, BE350, BE350G and BE350U models. They also match the CyberPower CPS300SL, CPS320SL, CPS325SL and 325SL units. Each cell uses AGM chemistry for maintenance-free operation.

Suits Small UPS and Alarm Panels

The 3.3 Ah capacity is sized for desktop UPS units, emergency lighting, fire alarm panels and security systems listed in the compatibility table. Buyers who need longer runtime for larger UPS cabinets or higher-wattage loads should look at higher-capacity packs.

Two-Cell Pack Delivers 3.3 Ah at 12 V

Each battery measures 5.28 by 2.64 by 2.4 inches with terminals spaced 1.6 inches apart. The pair provides enough capacity for typical desktop backup and low-draw monitoring gear, but will deplete quickly under heavy server loads or extended outages.

Questions about this item

Which UPS models does this 12 V 3.5 Ah battery replace?

It replaces the PE12V3AF1, PS-1230, UB1234 and WP3-12 batteries and fits APC RBC35 and RBC47 cartridges, CyberPower 325SL, CPS300SL, CPS320SL, CPS325SL, Conext CNB325 and several APC Back-UPS ES models including BE325-FR, BE350, BE350C, BE350ES, BE350G, BE350U and ES 325.

Can I use these batteries in an APC Back-UPS ES 350 that currently holds an older RBC35 cartridge?

Yes, the 12 V 3.5 Ah AGM cells are a 100 % OEM replacement for the RBC35 cartridge used in the Back-UPS ES 350, so the UPS will charge and run normally with the same 1.6 inch terminal spacing.

How do I confirm the batteries are working after I install them?

After installation let the UPS charge for the recommended period, then run a self-test from the front panel or management software; a passed self-test and normal runtime during a brief power pull show the 3.5 Ah set is operating correctly.
