  • 100 % OEM-compatible fit replaces UB1290 without modification
  • Maintenance-free operation eliminates water checks for 4-7 year life
  • Three-year warranty backs UPS and backup applications

12 V 7.2 Ah UPS battery

The BatteryJack UB1290 is a sealed lead-acid unit built with AGM glass-mat separators for maintenance-free operation. It serves as a direct OEM replacement in compatible UPS systems and backup devices. The non-spillable design meets IATA transport requirements and can be mounted in any orientation without electrolyte leakage.

AGM sealed lead-acid limits

The chemistry is optimised for float standby service rather than deep-cycling, so frequent full discharges will shorten the expected four-to-seven-year life. Gas recombination exceeds ninety percent during normal use, but the cells cannot accept water or specific-gravity checks. High ambient temperatures and sustained heavy loads will reduce practical runtime and overall longevity.

7.2 Ah capacity headroom

At the rated 7.2 Ah the pack comfortably supports typical desktop UPS loads for the short bridging periods these units are designed to cover. Extended outages or multiple high-draw devices will exhaust the reserve quickly, and the fixed capacity cannot be expanded without adding further battery modules. Users needing longer runtime must select a higher-capacity replacement or a UPS that accepts external packs.

Questions about this item

Should I choose the 7.2 AH version or a different capacity for my UPS?

Select the 7.2 AH model only if your UPS specifies a 12 V 7.2 AH battery; the UB1290 is a direct 100 % OEM replacement for that exact rating.

What does the 7.2 AH rating deliver once the battery is installed in my UPS?

It supplies 12 volts at 7.2 ampere-hours, giving the UPS its designed runtime for connected equipment during a mains outage.

What interface does the UB1290 use and what does it limit in practice?

The battery connects via standard UPS terminals; the AGM chemistry and sealed construction limit operation to maintenance-free, position-free use with over 90 % gas recombination.
