12V 3.3AH sealed lead-acid battery with AGM technology fits APC BE325 and RBC47 UPS units

  • Ready for immediate installation in compatible UPS units
  • Maintenance-free AGM design eliminates fluid checks and refills
  • 100 % OEM-compatible fit for APC BE325 and BE325CN models
  • Compact 5.28 x 2.64 x 2.4 in case suits tight chassis spaces
  • Expected service life of four to seven years under normal use

Direct Replacement

This 12V 3.3AH sealed lead-acid battery fits APC BE325 and BE325CN units as well as the RBC47 cartridge. It uses AGM chemistry for maintenance-free operation and is built to match the original dimensions and terminal spacing. Buyers who need a different voltage or a higher amp-hour rating will not be served by this unit.

Sustained Backup

The cell delivers consistent voltage across the discharge curve rather than a brief surge, supporting UPS loads for the duration of typical outages. Expected service life ranges from four to seven years under normal float conditions. Installations that demand rapid deep-cycle recovery or lithium-style energy density should look elsewhere.

Secure Fit

Terminals are spaced 1.6 inches apart to align with the APC chassis without adapters. The rugged ABS case measures 5.28 by 2.64 by 2.4 inches, allowing a direct drop-in replacement. Systems that use proprietary terminal shapes or non-standard mounting brackets cannot accept this battery.

Questions about this item

How much heat does the 12V 3.3AH SLA battery generate during continuous UPS operation?

Sealed lead-acid AGM chemistry produces minimal heat under normal float charge; the compact 5.28 × 2.64 × 2.4 in case dissipates it passively without a fan.

Which terminal spacing must my UPS chassis match for this battery to connect?

The terminals are 1.6 inches apart centre-to-centre, matching the standard F2 faston layout used by APC BE325, BE325CN, RBC47 and PS-1230 cartridges.

Will this battery fit the same slot as an RBC35 cartridge in my older APC Back-UPS ES 325?

Yes — the 5.28 in length, 2.64 in width and 1.6 in terminal pitch are identical to the RBC35 form factor used in BE325, BE350 and CyberPower 325SL units.
