Replacement Battery FIAMM RBC2 (for FUKAWA-FWU2) model 12325 is a sealed lead-acid battery compatible as a direct replacement for APC RBC2-style packs and designed for UPS units accepting the RBC2 form factor. The battery uses AGM (absorbed glass mat) technology with valve-regulated construction, allowing operation in any orientation and requiring no maintenance. Dimensions are 94 x 151 x 65 mm (HxWxD) and the weight is 2.2 kg.
This FIAMM replacement battery provides a maintenance-free AGM design with valve regulation for safe, spill-proof use and flexible installation orientation.

Turn off and disconnect the UPS from mains power before replacing the battery. Remove the UPS battery cover, disconnect the old battery's terminals (noting polarity), and remove the old battery. Install the FIAMM RBC2 replacement by connecting terminals with correct polarity, secure the battery in place, and replace the battery cover. Reconnect the UPS to mains power and follow the UPS manufacturer's procedure for initial charging and runtime testing.
Store and operate the battery in a dry, ventilated area within the temperature range recommended by the UPS manufacturer. Replace batteries in matching sets for multi-battery systems, and dispose of used batteries according to local regulations for lead-acid battery recycling.
