  • Maintenance-free AGM design simplifies upkeep

  • Two-pack provides a ready spare
  • Sealed lead-acid construction ensures rugged reliability

Replacement battery for ZB-12-2.3 devices

This 12V 2.3AH sealed lead acid battery is a direct OEM replacement for equipment using the ZB-12-2.3 model. It arrives new and ready to install in compatible UPS units, backup systems or power tools. The two-pack provides a spare or supports dual-battery configurations.

Advanced AGM maintenance-free build

Valve-regulated AGM technology makes the battery spill-proof and maintenance free, so there is no need to check electrolyte levels. The sealed construction allows safe operation in any orientation and resists vibration in portable tools or rack-mounted gear. Rugged casing protects the cells during daily handling and transport.

Upgrades ageing SLA cells in backup

The pack replaces worn 12V 2.3AH batteries that no longer hold a full charge, restoring runtime to spec. Expected service life is 4-7 years depending on duty cycle and temperature. The jump is worth it when runtime has dropped below usable levels or when a UPS self-test reports a battery fault.
