This is an old fashion way to possibly prolong the purchase of new batteries for your golf cart.  This is hit or miss depending on how long your batteries have sat without a charge or how long they last after they are charged,  or if they take a charge at all.   Two basic ingredients are all you need.


Step 1: Tip the battery on its edge and allow approximately half the battery acid to run out of each cell and into a plastic container.  Clean the battery with your paintbrush dipped in a baking soda solution. Rinse your battery with plain water, making certain none of the water gets into any of the cells.

Step 2: Mix 8 ounces of Epsom salts into 2 quarts of warm distilled water.  Stir thoroughly.  Use a turkey baster to fill each battery cell with the Epsom salts solution until the cells are completely covered.

Step 3: Put the battery or batteries on a charger – let them go through the whole cycle or charge overnight.

Epsom salts basically removes the sulfication or deposits on the battery plates which can prevent your battery from taking a full charge.  Check the battery after it has charged for several hours or the next day. If the battery still hasn’t taken a full charge, they cannot be saved and it is time for some new golf cart batteries .  If the battery has taken a charge, replace the cell caps and use your golf cart for a long ride and see how long the charge lasts.  If the ride and power is short lived it is still likely you will need to replace your golf cart battery.

It is also quite possible that your golf cart battery charger is not charging properly.  You will need a volt meter to check the power output of your battery charger.   Just attach it to the battery bank once the charger has been hooked up to the golf cart and turn it on.  The voltage of the golf carts battery bank should jump up from the static state before you turned on the golf cart battery charger. You should always hook up your golf cart charger  to your golf cart after use to keep the batteries in peak condition.  Learn more about your golf cart battery charger

Hi Pete, My golf cart batteries (Yahama) do not complete 18 holes anymore. I have been using the golf cart about 6 times a month over the last 4 years. When I start the round the charger indicates that the batteries are fully charged. I get to about hole 15 and then the batteries are drained. So these batteries have been on the charger permanently for the last 4 years except for when the cart is being used. Will the Epsom salts work with these batteries and if so must I drain the batteries first before doing the job or can I add the epsom salts while the batteries are “fully charged”. I live in South Africa

Bruce – Sounds like the batteries have lived a full life. But epsom salt is always a cheap alternative to try before replacing the batteries in your cart. Average cycle life for a lead acid battery is approx. 150-200 cycles at 50% DOD ( Depth of Discharge )

I would try to add a table spoon of salt to each battery cell… shake them up a little and then use it… Usually takes a few charge / discharge cycles to see any improvement.
