Venom Limited Lifetime Warranty

We are certain of the quality of all Venom products. Therefore, all Venom products come with our Limited Lifetime Warranty, which covers defects in materials or workmanship for the life of the product. Venom will repair or, in its discretion, replace defective product free of charge for a period of 1 year from the original date of purchase. After that, for any defective product you will receive a credit equal to thirty percent (30%) of retail price (as shown on manufacturer's website) toward the purchase of a new Venom product of the same size and type. We reserve the right to substitute different sizes or types of replacement product for product sizes or types that have been discontinued.

This is a non-transferable warranty and does not cover normal wear and tear, physical damage (including water damage), battery failure due to over-discharge (as described in our written instructions) or any damage resulting from improper use (including opening of the sealed battery pack).

This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state.
