USA & Canada Warranty

International (Outside USA & Canada)

Warranty Policy
Maruson Products (“Product”) includes Limited Warranties (“Warranty”, “Warranties”) offered to customers who register their product within fifteen (15) days of the invoice date. These Warranties are only for the original end-user (“Original Purchaser”). Please retain a copy of your receipt as proof of purchase. The Warranty period for your Product starts on the original date of purchase as shown on the sales receipt or invoice. Proof of purchase is required for any Warranty service and claims. Please retain a copy of your receipt as proof of purchase. Terms and conditions apply.

Maruson warrants the Original Purchaser of their Product that the product is free from defects in materials and workmanship under normal use and service for which the product was designed for a period listed below based on their product type. If, in the opinion of Maruson, there is a defect and is defective within the scope of this Warranty, Maruson’s sole obligation will be to repair or replace the defective UPS or battery. No salesperson, employee, or agent of Maruson is authorized to add to or vary the terms of the warranties. By using the Product, you agree to the terms of the Limited Warranty. The duration of warranty coverage does not pause, restart, or extend if the Product is with Maruson or any of its dealers for evaluation, servicing, repairs, or if a replacement part or unit is provided.

If an official distributor or dealer of Maruson products offers an extended warranty, the terms and execution of the extended warranty are strictly between the customer and the distributor or dealer.

If any payment is required as part of a service, Maruson’s obligations under this warranty are expressly conditioned upon receipt by the customer of all payments due to it (including interest charges, if any). During such time as Maruson has not received payment of any amount due to it for the Product, in accordance to the contract terms under which the Product is sold, Maruson shall have no obligation under this warranty.


Connected Equipment Warranty (CEW) Some Products sold in the US and Canada may include a Connected Equipment Warranty (CEW). It is not a warranty offered for all Maruson products, or for products purchased or used outside the USA or Canada.

The Connected Equipment Warranty is a Limited Warranty, subject to the limitations and exclusions set forth in the Warranty policy and only covers claims from damage of any properly connected equipment due to failed AC protection circuitry from an AC power-line transient surge. Furthermore, the Connected Equipment Warranty is not deemed “first dollar” coverage. It is secondary. If you have any other source of payment for your loss, such as insurance, another warranty, or an extended warranty or purchase protection plan (“Primary Coverage”), Maruson will pay only to the to the extent that the Primary Coverage does not cover the loss. Maruson’s obligation is reduced by any amounts that you are entitled to recover from the Primary Coverage, whether or not you make a claim for recovery under the Connected Equipment Warranty. The cumulative limit to be paid by Maruson under this warranty is up to USD 25,000.

Maruson will spend to repair or replace the damaged connected equipment, at Maruson’s option, an amount equal to the fair market value of the damaged equipment or the original purchase price of the equipment, whichever is less. The fair market value of the equipment shall be the current value for the equipment specified in the most recent edition of the Orion Blue Book by Orion Research Corporation or on eBay. Whenever claims are settled, Maruson reserves the right to be subrogated under any existing insurance policies the claimant may have.
