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.
