Limited Three-Year Warranty and Exclusions 

 

Marathon Power warrants to the original purchaser, and not for the benefit of anyone else that this product at 

the time of its sale by Marathon Power is free of defects in materials and workmanship for three (3) years 

(batteries for 2 years within the USA, Canada and Mexico, otherwise 1 year) from the original purchase date. 

Marathon Power will correct such defects by repair or replacement, at its option, if within such three-year period 

the product is returned prepaid and all warranty claim instructions are followed. This warranty excludes labor for 

removal or reinstallation of this product. This warranty is void if this product is installed improperly or in an 

improper environment, overloaded, misused, opened, abused, or altered in any manner, or is not used under 

normal operating conditions or not in accordance with all labels or instructions. There are no other or implied 

warranties of any kind, including merchantability and fitness for a particular purpose, but if any implied warranty 

is required by the applicable jurisdiction, the duration of any such implied warranty, including merchantability 

and fitness for a particular purpose, is limited to three years. Marathon Power is not liable for incidental, indirect, 

special or consequential damages, including damage to, or loss of use of, any equipment, lost sales or profits 

or delay or failure to perform this warranty obligation. 

 

 

Limitations & Claims 

 

This warranty does not cover any Marathon Power UPS or any properly connected electronic equipment which 

has been improperly installed, overloaded, abused or altered in any manner, or is not used under normal 

operating conditions, or in accordance with any labels or instructions, and does not cover any damage to properly 

connected electronic equipment resulting from a cause other than a “surge”. 

Damage caused by failure to provide a suitable installation environment for the product (including, but not limited 

to, lack of a good ground) will not be covered by this warranty. This warranty does not apply to damage caused 

by direct lightning strikes, or damage caused by electrical disturbances that exceed published product 

specifications. These products are intended to limit the maximum amplitude of transient voltage surges on power 

lines to specified values. They are not intended to function as surge arrestors. The UPS is intended to be installed 

on the load side of the service entrance and has been tested to verify that transient voltage surges are limited 

when subject to non-repetitive transient voltage surge events. This warranty excludes any incidental, indirect, 

special or consequential damages, including without limitation, labor for removal or reinstallation of the Marathon 

Power UPS or any connected electronic equipment, data loss or alteration loss of equipment use, lost sales or 

profits and any such damages for delay or failure to perform this warranty obligation. This warranty is in lieu of 

and excludes all implied warranties of merchantability or fitness for use. In addition, the warranty does not cover 

restoration of lost data and reinstallation of software. Some states may not allow the exclusion or limitation of 

incidental or consequential damages or other remedies, so the above exclusions or limitations may not apply to 

you. 

Take the following steps to file a warranty claim: Contact us at Marathon Power, Inc., Attn: Returns, 2538 E. 

54th Street, Huntington Park, California 90255 or call (310) 689-2328 within 30 days of the occurrence. Be 

prepared to provide detailed information about the event, any damage, the UPS model number, purchase date 

and location. You will then be provided with a Return Authorization Number (RAN), and be instructed to forward 

your proof of purchase (receipt), an explanation of the event and your UPS. If Marathon Power determines that 

the damage was due to a “surge”, we may request that all connected equipment be submitted for evaluation. 

Marathon Power is not responsible for shipping costs. In the event that the equipment has been damaged by a 

“surge” Marathon Power will reimburse you for repair or replacement at fair market value (on a pro rata basis) 

as indicated by the respective amounts above. The warranty coverage is above and beyond, only to the extent 

needed, of that provided by any other source, including but not limited to any connected equipment coverage, 

any manufacturer’s warranty or insurance policy. To receive payment for repair to damage due to a “surge,” the 

original purchaser should (upon prior approval from Marathon Power) have such equipment repaired by an 

authorized service center of such equipment’s manufacturer. The original purchaser will submit a repair bill along 

with a statement from the repair facility documenting the nature of the damage and how it was sustained to said 

equipment.
