BatteryJack inc. 12V 8AH SLA Battery 4PK

SKU CH-J5HJ-E2ZXG

Four-pack of 12 V 8 Ah sealed lead-acid batteries with AGM technology, maintenance-free design and over 90 % gas recombination

  • 12V 8AH SLA battery powers UPS and backup devices
  • Advanced AGM technology delivers maintenance-free operation
  • Sealed construction prevents electrolyte leakage in any position
  • Gas recombination system recovers over 90% of generated gas
  • 100% OEM replacement for UB1280 NP8.5-12 PS-1280 GP1280 BP8-12

Four-Pack 12 V 8 Ah SLA Batteries

This set contains four sealed lead-acid batteries rated at 12 volts and 8 ampere-hours each. They are direct replacements for models such as UB1280, NP8.5-12, PS-1280, GP1280 and BP8-12. The absorbent glass mat design keeps the electrolyte immobilised so the units can be mounted in any orientation without leakage.

Sustained Float Service and Gas Recombination

The cells are built for continuous float operation with a projected service life of four to seven years. Over ninety percent of gas generated during normal charging is recombined internally, which prevents pressure build-up and eliminates the need for water top-ups. This maintenance-free behaviour remains stable across the full expected service interval.

Sealed Non-Spillable Construction Limits

The completely sealed case meets International Air Transport Association requirements for non-spillable classification, allowing transport by air without special hazardous-material handling. Because the electrolyte is absorbed in glass mat separators, the batteries cannot be topped up or have their specific gravity checked; once capacity degrades below usable levels the unit must be replaced.

Questions about this item

Does the 12 V 8 AH SLA battery generate heat or noise during continuous float charging?

Sealed AGM construction recombines over 90 % of gas internally, so the battery runs silently with no measurable heat rise under normal float conditions.

What existing hardware must I already have to use these four batteries as a direct replacement?

A device or UPS designed for 12 V 8 AH SLA packs with standard F2 terminals — common models include UB1280, NP8.5-12, PS-1280, GP1280 and BP8-12.

Will the 12 V 8 AH AGM pack work reliably alongside older 12 V 7 AH or 9 AH batteries in the same string?

Mixing capacities is not recommended; the 8 AH units should replace an entire string of identical voltage and capacity cells for balanced charging and maximum service life.
