Who Should Buy This Replacement Battery

Critical Fit Specification: 12V 9Ah

The single specification that decides compatibility is the 12V 9Ah rating combined with F2/T2 terminals in the 5.95" X 3.75" X 2.56" form factor. Verify your UPS label matches these exact electrical and physical parameters before ordering.
