Thermoil® De-Mister Eliminates Golf Cart Battery Corrosion Greatly Extends Battery Life Greatly Reduces Water Consumption & Toxic Fumes Treats One 6, 8, or 12 Volt Battery. Made in USA.

One cell in battery was pretty weak (50-75%) and another slightly less weak (<100%). Internet search led to Thermoil Demister. 2 weeks ago I added it to each of 24 cells. 3 days ago I checked specific gravity and cells were much stronger (all 100%). Added 1-2 oz distilled water to several cells. Went to unplug last night and the Charging Light was glowing GREEN (working again)! I am very impressed.

I have purchased both of the therm oil products. I have used the products in a 6V battery bank. I have seen significant improvements in charge capacity & voltage.

Ok

This is the second year I'm winterizing my 2018 RV with this product on the 2 original 12vdc deep cycle house batteries. I am very pleased how well it recovered them both last year from the brink of replacement, and about how well they faired during 6 months of being parked at a campsite this year with few opportunities for charging. The RV's back home now and the batts are on the 24/7 smart charger, but I still use the RV all winter here in the Northeast. They consume much less water than before and hold their voltages even into freezing temperatures. The terminals are always clean too. This product works and it definitely bought me another 2-3 years of use from my batteries. Good find.

I have only been using this product for a month but the results so far are good. I'll provide an update after a few more months using the product.It's expensive but it still may be a good value if it extends the service life of the batteries and eliminates corrosion in the battery compartment. Update to follow.

I must say, I'm very excited to see this product on Amazon! I've been using it for over 20 years now, in various batteries and LOVE IT!! I'm finally replacing my (2) 27DC deep cycle marine batteries in my boat after 11 YEARS of use! That's simply unheard of.Bar none, this product makes batteries last much longer. Hell, I hear most people replace their deep cycles after 3-4 years... and I got basically TRIPLE that. A Big thanks to Thermoil for their product... it saves me money and goes a long, long way!! It's well worth the price. You're spending a good amount money on batteries... why not take the final step to protect them?!?Do yourself a favor and get this in your batteries immediately! You won't be disappointed.

File directions to the t didn't work thank you bye.

I was skeptical about this stuff because it’s expensive. It’s one bottle per battery basically but it really does work. I have eight batteries in one RV six in the other six in the golf cart to in the truck and I am very impressed.

It just works, saving my battery

spead up my golf cart almost right away. needed 4-5 bottle for 6 batteries

I'M HAPPY WITH THE PRODUCT
