After 4 years my cart batteries were not getting a full charge. Replacements were $850 so you understood why I tried the product. Took over an hour to empty the cells and add the product. I discharged and trickle charged the batteries 4 times on the golf. Course. Well nothing has changed but the $20 was worth a shot
