In many situations, golf cart batteries can be recharged and revitalised with just a little bit of Epsom salt. When dealing with batteries of any type, it is important to observe proper safety procedures and wear protective clothing and safety glasses. Epsom salt and all of the tools used to recharge your golf cart battery with Epsom salt can be purchased from local or online hardware and general stores.
Disconnect your golf cart battery from the battery terminals to ensure that there is no power feeding into your battery.
Remove the battery from your golf cart. The batteries are generally located under the front seat on golf carts.
Remove the battery cell caps from the golf battery. These can be pried off by sliding the tip of a flathead screwdriver under the cell caps and prying them off. Be careful when removing the cell caps--make sure you do not spill the battery acid inside of the golf cart battery onto yourself or a surface that can be damaged by the acid.
Remove half of the battery acid from each battery cell of the golf cart battery using a turkey baster. Safely contain the used battery acid in a glass jar or bottle.
Mix 2 quarts of distilled warm water with 227gr of Epsom salt. Stir together with a spoon until the Epsom salt is completely dissolved in the water.
Fill the battery cells with your Epsom salt mixture using the turkey baster. Make sure the battery plates are completely covered.
Hook up your battery to a battery charging station and allow the battery to charge overnight at the recommended voltage. It is generally recommended that golf cart batteries be charged to between 2.3 and 2.4. After charging, let the battery sit for at least 24 hours before you reattach it to the golf cart and use it.
Place the battery in the golf cart and reconnect the battery cables. Test the battery to see if it will hold a charge. You may need to repeat this recharging process several times before the battery will successfully hold a charge.
