How to Restore Golf Cart Batteries with Epsom Salts

Golf cart batteries are an essential component of your golf cart’s performance. However, over time, the batteries can lose their ability to hold a charge, reducing the range and lifespan of your golf cart. One popular method to restore the performance of golf cart batteries is by using Epsom salt.

Here’s how you can restore your golf cart batteries with Epsom salt:

Step 1: Gather Your Materials You will need the following materials:

  • Epsom salt
  • Distilled water
  • Plastic funnel
  • Safety goggles
  • Rubber gloves
  • Battery charger
  • Screwdriver
  • Battery hydrometer

Step 2: Remove the Battery Caps Before beginning the restoration process, make sure the battery is disconnected and the caps are removed from the battery cells. Wear safety goggles and rubber gloves to protect yourself from the battery acid .

Step 3: Prepare the Epsom Salt Solution Mix a solution of Epsom salt and distilled water. The ratio is typically 1 ounce of Epsom salt to 1 gallon of distilled water. Mix the solution in a plastic container until the salt is completely dissolved.

Step 4: Add the Epsom Salt Solution to the Battery Cells Using a plastic funnel, pour the Epsom salt solution into each battery cell until the fluid level reaches just below the bottom of the cell’s fill hole. Be careful not to overfill the battery.

Step 5: Recharge the Battery After adding the Epsom salt solution, recharge the battery using a battery charger. Follow the manufacturer’s instructions for recharging the battery. Make sure the battery is fully charged before using it again.

Step 6: Test the Battery Use a battery hydrometer to test the battery’s specific gravity. A fully charged battery should have a specific gravity reading of around 1.265. If the reading is below this, recharge the battery and test it again.

Step 7: Repeat the Process if Necessary If the specific gravity reading is still low after recharging the battery, repeat the process with the Epsom salt solution.

Additional Tips

Here are some additional tips and information to keep in mind when restoring golf cart batteries with Epsom salt:

  • Be patient: The process of restoring a battery with Epsom salt can take several days or even weeks, depending on the condition of the battery. It’s important to be patient and allow the solution to work its magic over time.
  • Use distilled water: Using tap water can introduce impurities and minerals that can interfere with the chemical reaction between the Epsom salt and the battery acid. It’s important to use distilled water to ensure a clean and effective solution.
  • Don’t overfill the battery: Overfilling the battery can cause the solution to spill over and damage the battery or surrounding components. Make sure to fill the battery cells to the appropriate level as indicated by the manufacturer.
  • Avoid using too much Epsom salt: While Epsom salt is a great additive to restore the performance of golf cart batteries, using too much of it can actually harm the battery. Stick to the recommended ratio of 1 ounce of Epsom salt to 1 gallon of distilled water.
  • Monitor the battery regularly: Even after restoring the battery with Epsom salt, it’s important to monitor its performance regularly. Keep an eye on the battery’s specific gravity, charge level, and overall performance to ensure it’s operating at peak efficiency.
  • Consider professional help: If you’re not comfortable restoring your golf cart battery yourself, consider seeking professional help. A trained technician can assess the condition of your battery and recommend the best course of action for restoring its performance.
