12 V 9.0 Ah UPS Replacement Battery

The PowerStar UB1280-F2 is a sealed 12 volt 9.0 ampere-hour lead-acid battery built with AGM technology. It serves as a direct replacement for UPS units that originally shipped with 7 Ah or 7.5 Ah cells. The higher capacity extends runtime without changing the footprint. Maintenance-free design allows operation in any orientation.

Compatibility Check Before Ordering

Verify that your UPS accepts a 12 V block with dimensions of 5.94 length 2.56 width and 3.66 height in the same units as the original battery. Confirm the terminal type matches T1 or T2 as listed for this model. Ensure the battery compartment can accommodate the physical size and that the wiring harness reaches the terminals without strain.

Thermals Noise and Power Draw

AGM construction is sealed and non-spillable so the battery produces no audible noise during normal float or discharge cycles. Heat generation is minimal under typical UPS loads and the case remains cool to the touch. No active cooling or ventilation beyond standard UPS enclosure airflow is required. Self-discharge is low supporting the rated 4 to 7 year service life.

Questions about this item

What comes in the box and what must I source separately?

The battery ships as a single 12 V 9.0 Ah sealed AGM unit with F2 terminals; mounting hardware and cables are not included.

Should I choose the 7.5 Ah version or the 9.0 Ah model?

The 9.0 Ah model fits the same 5.94 x 2.56 x 3.66 inch footprint and replaces 7.5 Ah units directly.

What does the 9.0 Ah rating deliver in an actual UPS?

It stores more energy than a 7.5 Ah cell, extending runtime while fitting the existing battery compartment.
