PowerStar PS-1220 12V 2.3Ah UPS Battery

The PowerStar PS-1220 is a 12 volt 2.3 amp hour sealed lead acid battery built with AGM technology for maintenance-free operation. It serves as a direct OEM replacement in compatible UPS units and backup devices. The sealed construction prevents electrolyte leakage and allows safe installation in any position.

Suits UPS units needing this exact voltage

This battery fits systems that require a 12V 2.3Ah block with .187 terminals and a 4 to 7 year expected service life. Buyers whose equipment demands a different voltage, higher amp hour rating or larger terminal size should look at other models.

Terminal size .187 inches decides fit

The .187 inch faston terminal is the critical dimension that determines whether this battery connects to your UPS without adapters or cable changes. Verify the terminal specification on the unit you are replacing before ordering.

Questions about this item

Does the PS-1220 battery ship with cables or mounting hardware, or must those be sourced separately?

The unit is a standalone 12 V 2.3 Ah sealed lead-acid block with .187 terminals; cables, brackets or terminal adapters are not included and must be purchased separately if your UPS requires them.

My UPS lists both 2.0 Ah and 2.3 Ah versions — which PS-1220 capacity matches the original specification?

The PS-1220 is rated at 2.3 Ah; select this capacity when the original battery is marked PS-1220 or 12 V 2.3 Ah to ensure correct runtime and charger compatibility.

What does the 90 % gas-recombination figure mean for day-to-day UPS operation?

Over 90 % of gas generated during normal charge and discharge cycles recombines inside the sealed case, so the battery stays maintenance-free with no watering or venting required throughout its 4–7 year design life.
