PortaMaxPower: Home of the Industry-Leading Three Year Limited Warranty

PortamaxPower’s warranty is the best in the industry. Most manufacturers give you one year, maybe two… and they don’t even cover the battery! We are so confident in our product that we offer a Three Year Limited Warranty to our registered customers.  Commercial/Government Agency warranty is for one full year from purchase date.

Three Year Limited Warranty Details

PortaMaxPower, LLC warrants to the original consumer purchaser that our PortaMaxPower product will be free of material or workmanship defects for a period of three years from the date of purchase. This warranty is not transferrable.

This Three-Year Limited Warranty does cover our LiFePO4 batteries when properly maintained. Fully charge your LiFePO4 battery as soon as you receive your Solar Sentinel. Use it and fully recharge it at least once every six months thereafter. See the owner’s manual for additional instructions on operating your Solar Sentinel.

PortaMaxPower will repair or replace at our discretion, any PortaMaxPower product found to have a defect in material or workmanship, free of charge.

Warranty Exclusions – this warranty does not apply if the product has been modified, misused, or has been damaged by accident, abuse, or misapplication. Batteries not correctly maintained as described above and in the Solar Sentinel Owner’s Manual are also excluded from this warranty.
