BatteryJack inc. 2PK 6V 12AH SLA Rechargeable Battery UPS Replacement Battery

SKU CH-2Z92-1R1PJ

Two-pack of 6 V 12 Ah sealed AGM batteries for UPS, alarm and feeder backup

  • Two-pack delivers 12 Ah each for extended runtime
  • Advanced AGM technology provides 90% gas recombination for safe operation
  • Sealed non-spillable design allows mounting in any position
  • Maintenance-free construction requires no water checks or refills
  • 100% OEM compatible replacement fits UPS and backup devices

2-pack 6 V 12 Ah sealed lead-acid batteries

This pair of 6 volt 12 amp-hour SLA units uses AGM construction and is sold new as a direct OEM replacement. They are built for standby power in UPS units, alarm panels, feeder systems and similar backup applications. The sealed case prevents electrolyte leakage and allows operation in any orientation. A three-year warranty covers UPS and backup use.

Replaces worn 6 V 12 Ah SLA cells

Swapping out aged batteries restores full runtime when the original set no longer holds charge or shows voltage sag under load. The upgrade is worth it when the UPS self-test fails, runtime drops below requirements or the existing pack reaches the four-to-seven-year design life. Gas recombination above 90 percent keeps internal pressure stable during normal float service.

Fits standard 6 V 12 Ah battery compartments

Two units wired in series provide a 12 V string for common UPS chassis without modifying trays or cables. Maintenance-free design eliminates water checks and specific-gravity readings, freeing up service time. Non-spillable classification meets IATA requirements for air transport and allows flexible mounting in racks or enclosures.

Questions about this item

What are the voltage and capacity ratings so I can match my UPS specifications?

Each battery is 6 V and 12 Ah; the pack contains two identical units for series or parallel wiring.

How do I install these in my UPS without reversing polarity?

Disconnect power, remove the old pack, connect red to positive and black to negative on each battery, then secure the hold-down brackets.

When should I plan to replace them in a UPS running continuous float charge?

Expect 4 to 7 years of float service; schedule replacement at the 4-year mark for critical loads.
