RefurbUPS BU304000 Replacement Battery Kit

This replacement battery kit is designed for compatible UPS units requiring the BU304000 specification. It contains two 6V 4.5A batteries supplied factory fresh. The kit restores backup power capability for supported Belkin UPS models. It is intended for users maintaining existing power protection systems.

Check Connector Type and Physical Fit Before
