12V 7Ah AGM Battery for FiOS Backup

The BatteryJack inc. 12V 7Ah GT12080-HG is a direct replacement for the PX12072 unit used in FiOS backup systems. It uses advanced AGM technology with a sealed, non-spillable construction that meets IATA transport requirements. The absorptive glass mat system absorbs electrolyte for steady service and prevents leakage in any mounting position. Designed for maintenance-free operation, it requires no water top-ups or specific gravity checks during its service life.

120% OEM Replacement Guarantee

This unit is built as a 100% OEM replacement, ensuring physical and electrical compatibility with the original FiOS backup hardware. The sealed construction and gas recombination design control over 90% of gas generated during normal use, allowing safe operation in any orientation. With an expected battery life of four to seven years, it provides a reliable long-term power reserve for critical communications equipment. The maintenance-free design eliminates the need for periodic servicing once installed.

Ideal for FiOS Backup Maintenance

This battery suits technicians and homeowners replacing a depleted PX12072 in a FiOS backup unit who need a drop-in, maintenance-free AGM cell. Buyers requiring a different voltage, capacity, or form factor for non-FiOS UPS or alarm panels should verify specifications before ordering. It is not intended for applications demanding user-serviceable flooded cells or higher amp-hour ratings than the stated 7Ah. The three-year warranty covers UPS and backup device installations.
