BatteryJack inc. 12V 9AH AGM UPS Replacement Battery

SKU CH-RR52-PCZFR

A 12 V, 9 Ah AGM battery built for UPS units, sealed for leak-free use in any position and rated for four to seven years of service

  • AGM tech prevents electrolyte leakage for safe operation
  • 100% OEM replacement fits existing UPS units directly
  • Maintenance-free design needs no water or gravity checks
  • Gas recombination recovers over 90% of generated gas
  • Expected service life of 4 to 7 years

UPS Replacement Battery

This 12V 9AH AGM battery serves as a direct replacement for compatible uninterruptible power supply units. It is built for server rooms, network closets and workstation backups that need reliable standby power. Buyers who need a different voltage or higher amp-hour rating will need another model.

AGM Technology Benefits

The absorptive glass mat design absorbs electrolyte into fine glass-fibre separators, preventing leakage and allowing safe operation in any orientation. Gas recombination exceeds 90 percent during normal use, so the battery remains maintenance-free for its entire service life. No watering or specific-gravity checks are required.

Capacity and Service Life

Rated at 12 volts and 9 amp-hours, the unit delivers steady power for typical UPS loads until the inverter signals low battery. Expected floating life spans four to seven years depending on temperature and discharge cycles. It is not suited for applications that demand deep-cycle endurance or capacities beyond the stated rating.

Questions about this item

How long before the 12 V 9 Ah AGM battery needs replacing?

The expected floating service life is 4 to 7 years, and the sealed AGM design requires no electrolyte checks or water top-ups during that period.

What limits runtime when the UPS runs on battery for extended periods?

The 9 Ah capacity determines how long the unit can supply power; once the stored charge is depleted the UPS will shut down until mains returns.

Does the sealed AGM battery generate noticeable heat or noise during all-day float charging?

The recombination system handles over 90 % of gas internally, so the battery stays sealed, silent and produces minimal heat under continuous float operation.
