Shop compatible aftermarket replacement batteries for Xtreme Power Conversion UPS systems. Match the UPS model, replacement SKU, battery count, voltage, capacity, terminal style, and connector arrangement before ordering.
These are compatible aftermarket replacement products. They are not manufactured, authorized, or endorsed by Xtreme Power Conversion.
When the battery light comes on an Xtreme Power Conversion UPS, the electronics are usually fine and the batteries are simply at the end of their service life. This collection lists our compatible replacement batteries for the XPC families sold in Canada, by model: the A, C, S, V, XST and XVT units, the P80, P90 and P91 series, the G90, GT90, T90, T91, TX90 and TX91 series, the NXRT, NXRi, NXTi, XVRT and XPRT units, the E90, E91 and X90 systems, and the EBP80 and BP external battery packs.
These are our compatible batteries, built and tested in house. They are batteries only: you reuse the casing, tray and wiring from your existing battery assembly, which keeps the cost down. Model numbers below are the XPC model the battery set fits. Most listings are complete sets; several compact models up to 1000 VA (A60, A70i, C60, S70, V80-700, XST, XVT) are listed as a single battery, and the listing says which.
A representative selection. The full list by UPS model is in the product grid below.

Every listing in this collection is batteries only: you transfer the new batteries into your existing tray and casing. Match the exact model on the UPS label before ordering.
Read the label, not the box art. XPC model numbers differ by one letter or digit between siblings, and the batteries can differ with them: the V80-1000 takes 7 Ah batteries, the V80-1000HT 9 Ah. The exact model on the UPS label is the search term.
Know what "batteries only" means. You keep your tray and wiring harness; the new batteries drop in where the old ones came out. If your harness is corroded or a connector is heat-damaged, tell us before you order.
Replace the set, not the sick cell. The batteries in one UPS age together. Replacing a single weak cell leaves its tired neighbours to drag the new one down within months.
Match the frame on modular systems. X90 battery sets follow the frame reference (X90-2S50k to X90-2S140k). M90 frames take battery trays, listed in the XPC accessories collection.
Plan the swap. Compact units swap batteries with the UPS off; online models that support battery hot-swap do it with the load running, following the manual's sequence.

Are these batteries made by Xtreme Power Conversion?
They are our compatible batteries, built and tested in house for the listed XPC models. The XPC model number names the UPS the set fits.
Do I get a cartridge or loose batteries?
Batteries only, by design: you reuse the casing and wiring from your existing assembly.
How long does the swap take?
Compact units take minutes once the UPS is off. Modular trays follow the manual's sequence. Have a flat surface and a screwdriver ready.
What if my UPS is not in the list?
Send us the model on the label. The full grid covers more models than the table above.
Do you take the old batteries back?
Lead-acid batteries recycle. Ask about lead-acid take-back options with your order.
What battery chemistry do the sets use?
Sealed lead-acid (VRLA) maintenance-free batteries. Lithium-ion XPC models are not covered here; send us the model and we will check.
