ThermOil has been increasing battery life & greatly
reducing maintenance since 1992!

Our battery additive will increase your Marine Battery life.  We have been offering the 12 oz. bottle of ThermOil Battery De-MisterDeMister since 2000. Then in 2008 we came out with a companion product for de-sulfating a sulfated battery, called ThermOil Battery De-Sulfater. Look for the name ThermOil and then you can rest assured you have the best battery additives on the market, and both products are guaranteed!

We have customers all around the world that use our products and they love them and continue to use them. Not only are their batteries lasting longer saving them money but we also greatly reduce their maintenance costs.

We have been treating batteries since 1992 and we are not looking back.
