BatteryJack inc. 12V 18AH UPS Replacement Battery HR2212

SKU CH-05HD-ZYWV4

12V 18Ah sealed AGM battery replaces 20Ah units, delivers 4-7 year life with over 90% gas recombination

  • 12V 18AH capacity powers UPS units reliably
  • Advanced AGM technology prevents electrolyte leakage in any position
  • Maintenance-free design eliminates water checks for the service life
  • 90% gas recombination reduces internal pressure buildup
  • 100% OEM replacement fits HR22-12 and HR2212 models

12 V 18 Ah UPS replacement battery

This sealed lead-acid battery uses AGM technology to deliver 12 volts and 18 amp-hours of capacity for uninterruptible power supplies. It is built for maintenance-free operation and can be mounted in any position without electrolyte leakage. The non-spillable design meets International Air Transport Association requirements for safe transport. Expected service life ranges from four to seven years under normal float conditions.

Replaces 20 Ah HR22-12 and HR2212 units

The battery serves as a 100 percent OEM replacement for models rated at 20 Ah such as the BB Battery HR22-12 and HR2212. Swapping to this unit is worth it when the original pack no longer holds a full charge or when the UPS runtime has dropped below acceptable levels. Gas recombination technology recovers over 90 percent of generated gas during normal use, extending the useful interval between replacements. A three-year warranty covers UPS and backup devices while other applications carry a two-year term.

Verify voltage, capacity

Confirm that the existing UPS requires a 12 volt block and that the 18 amp-hour rating satisfies the runtime specification for your load. Check that the physical dimensions and terminal layout match the HR22-12 form factor so the battery seats correctly in the chassis. Ensure the charging circuitry is compatible with AGM chemistry and that no watering or specific-gravity checks are expected during service.

Questions about this item

What terminal type does the HR2212 use for UPS connection?

The HR2212 uses standard F2 faston tabs for direct plug-in to compatible UPS units.

Does the battery require any electrolyte filling before first use?

No, the AGM construction arrives fully sealed and maintenance-free with no filling needed.

When should the HR2212 be replaced based on the expected service life?

Plan replacement after 4 to 7 years of float service depending on temperature and discharge cycles.
