UPS Replacement Battery 12V 9AH

This sealed lead-acid battery serves as a direct replacement for UPS units using RBC5, RBC9, RBC22, RBC32, RBC33 or RBC48 references. It fits APC SU400 models and other compatible backup systems. The T2 terminals match the original connectors for a tool-free swap. Buyers needing higher amp-hour ratings or lithium chemistry cannot use this unit.

AGM Sealed Design Zero Leakage

Absorptive Glass Mat construction absorbs electrolyte so the battery operates in any orientation without spills. Gas recombination exceeds 90 percent during normal use, keeping internal pressure low and eliminating routine maintenance. The case is classified non-spillable for safe transport. No active cooling or ventilation is required in typical cabinet installations.

Drop-In Fit Standard Dimensions

The pack measures 5.94in long, 2.56in wide and 3.72in high, weighing 13.16lbs. These dimensions match the OEM footprint so existing battery trays and cable routing remain unchanged. T2 terminals accept the original ring lugs without adapters. Builds requiring front-terminal access or larger capacity packs will need a different form factor.

Questions about this item

How do I install the 12V 9AH SLA battery with T2 terminals into my APC SU400 UPS?

Disconnect the UPS from mains power, remove the front cover, unplug the old battery leads, connect the new T2 terminals matching red to positive and black to negative, then secure the battery and replace the cover.

What maintenance or replacement will this AGM battery need during its 4-7 year expected life?

The sealed AGM design is maintenance-free with no water topping required; plan to replace the unit once capacity drops below UPS runtime needs, typically after the 24-month warranty period.

What limit appears first when this 13.16lb battery runs under sustained UPS load?

The 9AH capacity at 12V sets the runtime ceiling; extended discharges will hit the amp-hour limit before thermal or voltage cut-offs activate.
