UPSPLUSBATTERY Help Center
Start here when you need help choosing a UPS system, finding a replacement battery, understanding battery technical terms, checking shipping or pickup options, or reaching a Canadian UPS specialist.
Find a replacement battery
Need an APC RBC cartridge, Eaton 744-series battery, Vertiv/Liebert GXT battery, Tripp Lite RBC, CyberPower battery, or AGM equivalent? Use the replacement battery help page to match by UPS model, OEM cartridge code, voltage, amp-hours, and battery count.
Choose or size a UPS system
Compare single-phase, three-phase, online double-conversion, medical-grade, rackmount, tower, lithium and refurbished UPS options. If you know your load and runtime target, the UPS sizing resources can help you choose the right system before you request a quote.
