Enexer Technologies ("the Manufacturer") warrants each Enexer Technologies Lithium Iron Phosphate (LiFePO4) Battery ("the Product") sold by Enexer Technologies or any of its authorized distributors or dealers in the United States and Canada to be free of defects in material and workmanship for a period of 10 years ("the Limited-Warranty Period") from the date it was purchased by the Purchaser. Batteries must be registered within 30 days or purchase to activate the 10 year limited-warranty.

Within the first 6 years of the Limited-Warranty Period, subject to the exclusions listed below, Enexer Technologies will replace or repair, if serviceable, the Product and/or parts of the Product, if the components in question are determined to be defective in material or workmanship. The Purchaser will be responsible for only courier costs during this period.

From the 7th year to the end of the Limited-Warranty Period, only cost of materials to be replaced and courier costs will charged to the Purchaser if the components in question are determined to be defective in material or workmanship.

Enexer Technologies has the sole discretion to determine whether the Product in question is defective in material/workmanship or subjected to the exclusions listed below.

Non-Transferable
This Limited-Warranty is to the original Purchaser of the Product and is not transferable to any other person or entity. Please contact the place of purchase regarding any warranty claim.

Warranty Exclusions
Enexer Technologies has no obligation under this Limited-Warranty for products subjected to the following conditions (including but not limited to):

1. Damage due to improper installation; loose terminal connections, under-sized cabling, incorrect connections (series and parallel) for desired voltage and capacity (Ah) requirements, reverse polarity connections, or short circuited terminals.
2. Environmental damage; inappropriate storage conditions as defined by Enexer; exposure to extreme hot or cold temperatures, fire or freezing, or water damage.
3. Damage caused by collision.
4. Damage due to improper maintenance; under-charging or over-charging the Product, dirty terminal connections.
5. Product that has been modified or tampered-with.
6. Product that was used for applications other than which it was designed and intended for, including repeated engine starting.
7. Product that was used on an over-sized inverter/charger without the use of a manufacturer-approved current surge limiting device.
8. Product that was under-sized for the application; including an air conditioner, motor, or similar device having a locked rotor start-up current that is not used in conjunction with a manufacturer-approved surge-limiting or current-limited protection device.
9. Product not stored in adherence to the Enexer's storage guidelines, including storage of the product at low state-of-charge.

This Limited-Warranty does not cover a Product that has reached its normal end of life due to usage which may occur prior to the end of the Limited-Warranty Period. A battery can deliver only a fixed amount of Energy over its life which will occur over different periods of time depending on the application and usage conditions. For example, cycling the battery more than 1 time daily, will cause the normal end of life to occur before the end of the Limited-Warranty Period.

Enexer Technologies reserves the right to deny a warranty claim if the Product is determined, upon investigation, to be at its normal end of life even if within the Limited-Warranty Period.

Warranty Disclaimer
Enexer Technologies' exclusive liability for breach of any warranty on the Product shall be to replace it within the Limited-Warranty Period in accordance with the terms of this Limited-Warranty.
