Step 1: Wear Protective Gear 

Before you begin doing anything, wear your protective gear. This includes an apron, gloves, and goggles. These safety gear will protect you from the splash of any acid that could be harmful to your body. 

Step 2: Open Battery Compartment and Remove the Battery

Start by accessing the battery in your golf cart. The batteries are placed under the front seat. So, to open the compartment, lift the front seat out of the cart. Check how your front seat is mounted on the cart and remove it carefully. Some cart models have their front seat hinged with a mechanism that can lift it up easily. 

After opening the compartment, use a wrench to remove the battery from your golf cart. 

Step 3: Clean The Battery Corrosion 

Mix 2 tablespoons of baking soda with a quarter litter of water. Use your toothbrush or paintbrush for the cleaning. All you need to do is dip the brush in the solution and brush off the corroded areas. The main focus should be mostly around the terminals. 

Expect the cleaning process to fizz and bubble when soda and battery acid come into contact. 

If the corrosion is stubborn, use steel wool to scrub it from the battery. Steel wool or sandpaper will give it an abrasive texture and peel off the corrosion. 

Lastly, dip your brush in plain water and wipe all the battery surfaces after cleaning. 

Step 4: Inspect The Battery 

Batteries get cracks or other defects. Thoroughly inspect it and ensure it’s in the right condition. Check if the case is leaking any acid or if any area is not well enclosed. If you find any battery cracks or defects, replace them. It doesn’t matter how good you’ll repair it. It will still be defective. 

Step 5: Remove The Plastic Caps 

Plastic caps cover the cells of the batteries. Remove them. All you need to do is push the end of the flat screwdriver under the cap and try to push it upwards. The cap will come out with a lot of ease. 

Step 6: Prepare A Distilled Water Solution 

Add 13% Epson salt into distilled water. Stir thoroughly to get a good solution. Then inspect every battery cell. And if everything is alright, add distilled water to the battery. You should add enough water that would cover all the plates. 

After refilling the battery, return the caps to their places. 

Step 7: Charge the Battery 

Charging the battery for about 8 to 12 hours is advisable using a three-phase charger set for 6-volt batteries. Ensure the recharging is set at a slow amp rate. But most importantly, ensure you have a proper terminal and wiser connection between the cell and charger. The red wire should go to the positive terminal, and the black wire should be placed on the negative terminal. 

The best way to do it is to get yourself a smart battery charger. This will take a lot of hassle and ensure you charge the batteries effectively. 

Step 8: Inspect The Charge 

After about 12 hours of charging, check the charge. If the battery shows that it has charged, open the caps and inspect the cells again. Add more distilled water in cells that have exposed plates. If all is well, then your battery will be ready to use. 

What If the Battery Doesn’t Charge Even After Following These Steps? 

If you follow all the above steps properly, your battery should be able to charge fully. But if it doesn’t, you didn’t add Epsom to the distilled water. Follow the steps below to re-do it again and get it charging. 

Step 1: Drain The Battery Acid 

Tip your battery on one edge. Allow up to half of the battery acid to run out of every cell. Drain the acid in a plastic container. And after draining the acid, use the baking soda solution you had prepared clean it. Also, remember to rinse with plain water while careful that no water gets into the battery cells. 

Step 2: Add Epsom Salt Soltuon 

Warm 2 quarts of distilled water and add about 8 ounces of Epsom salts. Stir well to get a mixed solution. Then add the solution into the cell until all places are covered. 

Step 3: Charge The Battery for About 12 Hours 

Repeat the charging process. Ensure your battery is charged at a slow amp rate for about 12 hours. It’s advisable to leave the battery charging overnight and check it in the morning. 

After 12 hours, check if the battery is fully charged. 

But it can’t be saved if the battery doesn’t charge even after repeating this process carefully. Forget about it and replace it with a new one. 

However, we are confident if you followed the steps later, you’d easily refurbish your golf cart batteries.
