Description

FIAMM FUKAWA FW 18-12U is a sealed 12V 18Ah rechargeable lead-acid battery designed for use in UPS units and other backup systems. The battery uses AGM technology with electrolyte absorbed in glass-mat separators and is valve-regulated, which allows operation in any orientation and requires no maintenance.
