BatteryJack inc. 12 V 2.3 Ah PS1220 UPS Replacement Battery

SKU CH-8BEY-KBGJC

A 12 V 2.3 Ah sealed lead-acid battery built as a 100 % OEM replacement for the PS1220

  • 12 V 2.3 Ah capacity powers UPS reliably
  • Advanced AGM technology enables maintenance-free operation
  • 100 % OEM replacement fits PS1220 units directly
  • Sealed valve-regulated design ensures safe handling
  • Expected 4-7 year service life supports long-term uptime

Direct OEM Replacement

This 12 V 2.3 Ah sealed lead-acid battery is built as a 100 % OEM substitute for the PS1220 unit. It uses valve-regulated AGM construction so the cell is maintenance-free and safe to handle in any orientation. The pack targets administrators who need a drop-in refresh for existing UPS hardware without rewiring or firmware changes.

AGM Chemistry Limits

Valve-regulated AGM cells deliver reliable standby power but self-discharge during long shelf storage and lose capacity if cycled deeply. The chemistry is optimised for float service rather than frequent full discharges, so runtime shrinks faster under heavy cyclic loads. Operating temperature extremes also accelerate ageing beyond the rated service window.

Refresh Versus Expansion

This unit restores original runtime to a UPS that has reached the end of its 4-7 year design life; it does not increase capacity beyond the factory specification. The jump is worth it when the existing pack no longer holds charge through a typical outage. Buyers who need longer backup time must choose a higher-capacity UPS instead of swapping this battery.

Questions about this item

Should I choose the 2.3 Ah version or a higher capacity for my PS1220 UPS?

Select the 2.3 Ah PS1220 unit; it is a 100% OEM replacement with AGM technology designed for the original chassis and runtime.

What does the 12 V 2.3 Ah rating deliver once installed in my UPS?

It supplies 12 volts at 2.3 amp-hours, giving the UPS its rated backup time while the maintenance-free AGM cells operate without watering.

What connection standard does the PS1220 use and what does it limit?

The battery uses the standard F2 quick-disconnect tabs that match the UPS harness, limiting installation to the original form factor and voltage.
