  • Advanced AGM technology delivers steady service with over 90 % gas recombination
  • Sealed non-spillable construction allows safe operation in any position
  • Maintenance-free design requires no water or gravity checks during service life

6V 12AH SLA Replacement Battery

This 6 volt 12 ampere-hour sealed lead-acid battery serves as a direct OEM replacement for NP8-6 and NPX-50 models. It uses absorptive glass mat technology to deliver maintenance-free operation in uninterruptible power supplies and backup devices. The sealed construction prevents electrolyte leakage in any mounting position. It is intended for users who need a drop-in power source for compatible UPS units.

AGM Technology Limits

The absorptive glass mat system absorbs sufficient electrolyte for steady service and recombines over 90 percent of gas generated during normal use. This design eliminates the need to check specific gravity or add water throughout the floating service life. The battery is classified as non-spillable and meets International Air Transport Association requirements for safe transport. Buyers requiring user-serviceable cells or higher energy density chemistries should consider other options.

Compatibility Check

Verify that your UPS or backup device specifies a 6V 12AH battery and accepts the NP8-6 or NPX-50 form factor before ordering. Confirm the terminal layout matches your equipment to ensure a proper connection. The expected service life ranges from 4 to 7 years under standard floating conditions. Units needing a different voltage, capacity or physical size will not be compatible.

Questions about this item

Should I choose the NP8-6 or NPX-50 version for my UPS?

This single battery replaces both the NP8-6 and NPX-50 models, so you do not need to pick between versions.

What does the 12AH rating mean for my UPS runtime?

The 12 ampere-hour capacity indicates the total charge the battery can deliver, directly setting the available backup time for your unit.

How does the AGM design affect daily use?

Absorbed Glass Mat construction makes the battery maintenance-free, spill-proof and usable in any orientation without electrolyte loss.
