Direct OEM Replacement

The CSB HR1234W F2 is a sealed lead-acid battery built to replace the original unit in compatible APC UPS systems. It uses absorptive glass mat construction so the electrolyte stays locked in the separator. The 12 volt, 9 ampere-hour rating matches the factory specification. Buyers who need a different voltage or capacity cannot use this model.

Leak-Free AGM Build

The glass-fibre mat absorbs all electrolyte, making the battery non-spillable and safe to ship by air. Gas recombination recovers over 90 percent of generated gas during normal cycling, so no watering or venting is required. The sealed case allows operation in any orientation without leakage. Users who want a serviceable flooded cell must choose another chemistry.

F2 Terminal Fit

Two faston tabs spaced for the F2 standard connect directly to the UPS wiring harness. The case measures 5.94 in length, 2.56 in width and 3.72 in height, matching the original footprint. Weight is 13.16 lbs. Builders whose chassis or cable layout needs a different terminal type or smaller envelope must select a different part.

Questions about this item

How often will the 12V 9AH AGM battery need replacement under normal UPS duty?

Expected service life is 4 to 7 years; the sealed AGM design is maintenance-free so no watering or terminal cleaning is required during that period.

What capacity limit appears first when the battery runs a continuous load?

The 9AH rating at 12V defines the total energy available; once that ampere-hour reserve is exhausted the UPS will shut down.

How much heat does the 13.16 lb sealed unit add to a rack running 24/7?

AGM chemistry recombines over 90% of generated gas internally, so self-heating stays low and the battery is rated for operation in any orientation without extra cooling.
