12V 9Ah UPS replacement battery

The BatteryJack 12V 9Ah Ritar RT1290 serves as a direct OEM replacement for compatible uninterruptible power supplies. It is designed for server rooms, network closets and workstations that require dependable backup power during outages.

Capacity and runtime

The 9Ah rating delivers sufficient reserve for typical UPS loads, supporting graceful shutdown of connected equipment. Runtime decreases as the load approaches the unit's maximum output, so critical systems should be sized accordingly.

AGM construction and sealed design

Advanced Absorptive Glass Mat technology keeps the electrolyte immobilised, preventing leaks and allowing operation in any orientation. The maintenance-free, non-spillable case meets IATA requirements for safe transport and requires no water top-ups over its 4-7 year expected service life.
