Before you order
How do I confirm this battery fits my UPS?
Find the model number on the back of your UPS (printed on the silver sticker next to the serial number). Check that the exact model, including any regional suffix, is marked as confirmed in the compatibility list above. If it is missing or marked as needing confirmation, email your UPS model number — we'll confirm compatibility within one business day.
What's the warranty, and who handles claims?
Replacement batteries carry a 1-year UPSPLUSBATTERY warranty against defects. Claims are handled by our team in Canada. Email info@upsplusbattery.com with your order number and a description of the fault. We will provide the next steps for your claim.
Is this an OEM battery or an aftermarket compatible?
Compatible aftermarket. We manufacture this pack to match the original electrical specification using new AGM cells, the correct connectors, and identical physical dimensions. We're not affiliated with the OEM. The trade-off: you save roughly 30–40% vs. the OEM cartridge, with the same runtime and a comparable warranty term.
