Battery Boost is designed to de-sulfate and restore your old, weak, slow golf cart batteries or your money back. Is your golf cart not running as long as it once was? Is it low on power? Or maybe it won't even move? Consider Battery Boost before replacing those expensive batteries! It could save you several hundred dollars! Simply add the minimum of 1.5oz per cell in your batteries, charge a few times to allow the chemical to react with the plates, and you're all set. This process can take up to 10 days to fully take place. 6 bottles included. This will treat up to 6 - 8 volt batteries in your cart.
