BatteryJack inc. 12V 9.0AH UPS Replacement Battery for APC SmartUPS 1400RM 2200RM3U UB1280

SKU CH-389K-3Z1FP

A 12 V 9.0 Ah sealed lead-acid battery with AGM technology, sized 5.94 × 2.56 × 3.66 in and T1/T2 terminals, replacing 7.5 Ah units in APC SmartUPS 1400RM and 2200RM3U models

  • 12 V 9.0 Ah capacity replaces 7.5 Ah units for longer runtime
  • AGM sealed construction prevents electrolyte leakage in any orientation
  • Fits APC SmartUPS 1400RM and 2200RM3U models directly
  • Maintenance-free design requires no watering or periodic checks
  • Three-year warranty covers UPS and backup applications

Direct Compatible Replacement

This 12V 9.0AH sealed lead-acid battery is a direct replacement for the UB1280 used in APC SmartUPS 1400RM and 2200RM3U units. It suits administrators who need to restore runtime without changing hardware. The AGM construction is maintenance free and classified as non-spillable for safe handling. Buyers who need a different voltage or terminal layout cannot use this unit.

Fits Existing UPS Chassis

The battery measures 5.94 by 2.56 by 3.66 and uses T1/T2 terminals that match the original connectors. It slides into the same battery compartment without cabling changes or bracket modifications. The increased 9.0AH capacity replaces older 7Ah or 7.5Ah cells and extends available runtime. Installations requiring a larger footprint or different terminal type will not accept this pack.

Sealed AGM Thermal Behaviour

Absorbed Glass Mat technology recombines gas internally so the case stays sealed during normal charge and discharge cycles. No electrolyte leakage occurs from the terminals or case in any mounting orientation. The design delivers steady voltage output with minimal self-discharge over a 4-7 year expected service life. Environments with extreme ambient temperatures may reduce the realised lifespan.
