Direct OEM Replacement

This 12 Volt 10Ah sealed lead-acid battery serves as a direct OEM replacement for compatible UPS units. It uses advanced AGM technology to deliver maintenance-free operation in a rugged, economical package. The design fits existing compartments without modification.

Capacity and Runtime Limits

The 10Ah rating at 12 Volts provides sufficient capacity for standard backup loads during typical outages. Runtime decreases proportionally as connected equipment draws more current from the UPS. Extended or high-wattage loads will exhaust the available reserve faster than light loads.

Three-Year Warranty Coverage

A three-year warranty applies to this battery when installed in UPS and backup devices. This coverage period reflects the manufacturer's confidence in the expected four to seven-year service life under normal conditions. The warranty distinguishes between UPS use and other applications.

Questions about this item

Will the 12 V 10 Ah battery fit the same slot as my old UB12100-S unit?

The replacement matches the UB12100-S form factor and F2 terminals, so it installs directly into the existing UPS bay without adapter cables.

How can I confirm the battery is delivering the rated 10 Ah after installation?

Run the UPS self-test or a calibrated load bank; the unit should sustain the rated load for the expected runtime based on the 10 Ah capacity.

Does the package include mounting brackets or terminal covers, or must I order them separately?

Only the sealed lead-acid battery with F2 terminals is supplied; brackets, covers or wiring harnesses are not included and must be sourced separately.
