Works with no sweat

I have installed this product in both of my golf carts and have had no sweat. It's worth it. No more adding water diluting the hydrometer reading. You use acid, not water.

Pros
  • Few competitors
Cons
  • Only available in white

Simple solution to extend RV battery life

I heard about this product from another RV enthusiast who swore it could significantly extend the life of their batteries. If he does everything he says, it's not a problem and it's necessary.

Pros
  • Excellent overall performance
Cons
  • Has flaws

I returned the batteries

I have about a dozen batteries that I wanted to throw away. However, I came across Thermoil and this product works wonders. I got all my dead batteries back. Definitely recommended for anyone who wants to give old batteries a second life.

Pros
  • Convenience
Cons
  • No automatic

Fixes dead batteries

Works better than expected. I desulfated 2 deep cycle batteries and then cycled, charged and discharged them multiple times. Both batteries are back and working great. Saved me buying two new batteries. I recommend Therm De Sulfater Oil to revitalize your sulfated batteries.

Pros
  • One year trial
Cons
  • 0

Let's see if the battery lasts another 8 1/2 years.

Just bought after not using it for years. I used this product many years ago in a pair of 31 series Trojan deep cycle batteries for my 24v trolling motor in my bass boat. I have had these batteries for 8 1/2 YEARS. Back then, a battery only cost about $8. I'm about to add the product to a new starter battery I just bought.

Pros
  • Hands-free operation
Cons
  • Lots of stuff

There is no seal on the bottle. The only thing that will prevent leakage during transit is *IF* the lid is tightly closed.

There are no seals on the bottle. The only thing that will prevent leakage during transit is *IF* the lid is tightly closed. Acid batteries that "die" from accumulation of material that spalls off the plates (causing an internal short circuit) rather than from sulfation.

Pros
  • Sturdy construction
Cons
  • Hard to tell

Works amazing! I am a customer for life! So happy it's finally on Revain

I'm so happy to see that Thermoil Battery DeMister is finally on Revain! I have been using this product for many years and cannot say enough good things about it. I own/rent seasonal gear so batteries were always an issue until I found Thermoil. DeMister has saved me so much money and I use it on ALL my cars. The company owner is also a great resource for answers to all your questions. I am a customer for life.

Pros
  • . Understood!
Cons
  • Dear

A must for every lead-acid battery!

I have to say I'm really excited to see this product at Revain! I've been using it in a variety of batteries for over 20 years now and LOVE IT! I have finally replaced my (2) 27DC deep cycle marine batteries in my boat after 11 YEARS! It's just unheard of. In addition, this product extends battery life. Heck, I heard most people replace their deep cycles after 3-4 years. and I got basically TRIPLE more. Many thanks to Thermoil for their product. it saves me money and goes a long way! It's worth

Pros
  • Best
Cons
  • Ugly packaging
