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

Wasn't sure this was actually going to work. But, I gave it a shot. Followed instructions on how to add this to my batteries. Charged the batteries before i added solution. After adding solution charged batteries. checked voltage. full charge even the next day. I will do this again in several years. works great.

This product is awesome! I bought a car that had been sitting for a year, the battery was from 2023 and only had 1.5v in it so dead, auto parts store said it was bad. I followed the instructions on the bottle which are simple, placed it to charge but my battery charger threw an error because it requires at least 2.5v to start charging so I placed the battery in my running vehicle for 15 minutes, the voltage got up to 7.5 but was dropping quickly while I checked it with the car off so I immediately placed it to charge, 16 hours later it was at 13.5v, holding the charge and starting the car great.

Did not work at all but the batteries were 6 years old

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.
