Check the complete cartridge before ordering
Compare the label and wiring on the existing assembly with the product photos. A shared base battery or matching voltage alone does not establish compatibility. Follow the UPS manufacturer’s replacement procedure; do not assume the battery can be replaced while equipment is powered. This listing supplies the battery cartridge, not the UPS.
Internal battery documents
The supplier identifies SG12180FP batteries inside this assembly. These documents describe the individual internal battery, not the assembled cartridge’s overall dimensions.
