Battery Renew Solution for Golf Cart Batteries - 64 oz Desulfator Refill - Refurbish, Repair & Restore Any 6 Volt, 8 Volt or 12 Volt Lead Acid Batteries - Made in USA - Non-Toxic Safe Refill Solutions

The acid works wonderfully and seems to have really bought me some life on my golf cart batteries.

My golf cart batteries are 3 years old and starting to fade. After a round of golf recently the smart charger failed to start charging so the next day I checked the battery and the electrolyte level was very low in every cell. I bought this product in hopes that it would revive my batteries enough to at least allow the charger to work. After adding Battery Renew the charger worked and charged all six batteries. The next day I tested the electrolyte levels again and each was up nearly to the normal range. I think results will vary depending on how well the batteries have been maintained. I always keep my batteries fully charged and keep the distilled water level in the normal range. Hopefully I will get a few more months of use before they need to be replaced.

It did nothing for my battery s, product may work for so batterys that have no voltage,, but I had surface voltage that would not hold under a load hoping this would help... It did nothing to improve it .

Seems to have helped some but time will tell if there's a longer term improvement. Will update if changes occur.

Works great, batteries would not take a charge connected up. Disconnected batteries and removed them from the golf cart. Batteries reading between 1volt and 2 volts. Only 2 of the 6 would take a charge from a 6 volt charger. Top up the distilled water and add the Battery Renew to each cell, shake the batteries and leave them for a few hours. All 6 batteries took a charge. Charge them to 75% and then refit them into golf cart. Charge batteries with 36v charger, all working. After a few days of use and charging the golf cart is operating good, with a good battery life, which seems to be getting better with more use.

Tried it on a twelve-volt car battery that’d been sitting dead for months. Mixed in the solution, waited the full day, charged it slow—and hey, it cranked without a stutter. Voltage holds steady now, though highways still drain it faster than fresh ones. Non-toxic part sold me, no weird spills or smells. Good bang for the bottle, especially since it’s made here. Just don’t expect miracles on totally fried cells. Update after few days battery wouldn’t hold a charge

It did what it said it was going to do. This I didn't think it was going to restore the batteries but it did do what it. Said it was capable of doing 5 out of the 6 batteries did get restored to working the way it had worked when the cart was brought.

Worked perfectly! My batteries were dead and out of acid. Filled the back up (took 7 bottles), but saved me from having to buy new batteries!!!
