12 Volt – 104 Amp Hour YUASA Battery

12V 104Ah High-Temperature VRLA AGM Battery

The Yuasa SWU425-12FR is a 12-volt, valve-regulated lead-acid (VRLA) battery using absorbed glass mat (AGM)
technology and Yuasa’s high-temperature HT X Alloy™ to deliver long life in demanding standby applications.
With 104 Ah at the 20-hr rate and up to 425 W/cell at 15 minutes (1.67Vpc, 25°C), it provides dependable
short-duration ride-through and robust backup power for UPS systems, datacenters, switchgear, and other critical loads.

The SWU425-12FR features a 10-year design life, flame-arresting one-way vent, epoxy-sealed terminals, and a
flame-retardant UL94V-0 ABS case for enhanced safety in high-density installations. Its maintenance-free,
non-spillable AGM construction meets or exceeds DOT and IATA requirements for non-hazardous transportation, while
top-mounted M6 terminals simplify cabinet and rack installation. Certified to ISO 9001, ISO 14001, and
IEC 60896-21 and recognized by UL, this battery is ready for modern enterprise and industrial environments.
