DeSulfater Golf Cart Solution Renews Restores & Revives Any Sulfated Lead Acid Battery Guaranteed! Treats Two 6, 8 or 12 Volt Batteries. Made in USA

I have a 2018 Jayco Seneca that I have had since. I admit that I did not maintenance my house batteries properly. I may have added distilled water to top them off a couple of times during the 5 years I’ve had them. I have 2 starter batteries that are sealed; and 4 of the pictures deep cycle batteries. Then for a couple months the battery was not holding a charge. Took it to Camping World and another RV place and they stated possible electrical issues.The point: I bought two bottles. I looked in my battery housing and it was almost bone dry for I don’t know how long. I added distilled water till the line and added 2 ounces per cell (3) per battery. Whatever was left to reach the fill point after the 2 ounces I added more distilled water.Day 1 battery started to hold charge; 3 weeks later and a couple trips it’s holding a charge all day and night with days in between starting the RV. Hope this helps someone. This product helped me save $800 bucks.

I bought this for some deep cycle solar batteries that I wanted to bring back to life, but found they were too old and gone before I tried it. The other day, my Chevy Silverado 3500 pick up suddenly was dragging and wouldn't start, so I decided this was the time to try out this product. I pulled both batteries (duramax diesel has two Interstate MT78's), put them on my charger and brought them back up to 14+ volts, then pulled an oz of acid out of each cell and added an ounce of this stuff, and charged them both again overnight. After that, I put them back in the truck, and not only did it fire up easily (to be expected after a full charge), but they maintained a high charge above 14v, per my dash gauge. I took it on a 30 minute drive on the highway to make sure they were getting a good charge. The truck started up each time I turned it off that day, and I was pretty happy to think I was going to avoid buying new batteries for awhile! But the next morning when I came out (25 degrees outside), the truck was back to dragging during ignition, and it would not start. I was really disappointed. Not only that it didn't work, but all the work that I did in pulling out the batteries, suctioning out the acid, putting them on the battery charger, putting them back in the truck, which is a pita. More that that, I was bothered that my $300+ Interstate batteries only made it 4 years, unlike all my previous ones which lasted between 6-8 years. Anyway, I ended up having to buy a new set of NAPA batteries for $340. I was really hopeful, but it just didn't work for me. How do I get a refund, now?

I recently had the opportunity to use Thermoil Golf Cart, RV, Boat Battery Restore Renew Liquid, and I must say, it exceeded my expectations. I've owned a used battery-powered golf cart for three years, and due to my neglect, the batteries had deteriorated to the point where the cart could barely make it around the block on a full charge.When I discovered Thermoil, I was initially skeptical, but the positive reviews and testimonials convinced me to give it a try. Spending around $80 to potentially restore my batteries was a much more appealing option than shelling out for a new set.Following the simple instructions on the bottle, I added Thermoil to the cells of my golf cart batteries. To my amazement, it worked exactly as promised. My batteries were rejuvenated to a like-new condition, and my golf cart now performs excellently.Thermoil not only saved me the cost of buying new batteries but also saved me the hassle of disposing of old ones. It's a cost-effective solution for reviving neglected batteries, and I highly recommend it to anyone facing a similar situation. It's a small investment that provides a significant return in terms of battery life and performance. Thermoil has earned my trust, and I'm glad I gave it a chance.

Hi. I am running two 48-volt and one 12-volt bank of Trojan L16E batteries on a fully solar house. The 12-volt group was going bad. That's two 6-volt batteries in series. One of the batteries n the 12-volt group was a consistent about 4-volts after discharge overnight and the other would drop to just under 6-volts. Both batteries showed low electrolyte quality on a hydrometer with the worst battery showing one bad cell.I picked up a bottle of this to try and got it all installed. Its best to do if the batteries are low. I had to remove the 2 ounces of electrolyte from each cell. no big deal. I replaced those 2 ounces with the battery additive as directed. After two days of normal use and recharging the lower battery dropped to 2-volts on discharge while the other battery lost about 1-volt under its last discharge rate. This was due to the other battery dragging it down I figured. I took one of the older batteries out of one of the 48-volt banks and replaced to bad battery in the 12-volt bank. The 12-volt bank began to work perfectly with only normal drop during discharge. I had to replace the bad battery with a new one.I don't know if the fluid helped the one good battery in the 12-volt bank but the electrolyte in the battery does show an improvement. This could be from it getting a better charge and discharging less at night.So moral of the story is, I don't know if it helped or not. I do know that the bad battery got worse after its use. I have other batteries that may benefit from the fluid that are showing that the electrolyte is getting weak. So, I might try again on those batteries. It's just something to consider.

Used it but I guess the battery was too far gone to recondition .

Excellent product, easy to add to battery, helps eliminate sulfation of battery. Liked price, ship-ped quickly liked price.

Doesn’t work

We have used this once so far and found it does give the batteries a better charge. 1st application I did find it to make my golfcart go a bit fast at take off. Will use a 2nd application to see if it performs even better
