How to Rejuvenate your old Golf Cart Batteries – a Step-by-Step Guide

EZGO Golf Cart-Battery BankThis is an old fashioned way to possibly delay 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: Epsom salts and distilled water.

Reconditioning your old batteries

Below is a tutorial which will help you out with reviving old golf cart batteries – to restore them to life!

You will need:

  • Battery charger
  • Epsom salts
  • Baking soda (and an old paintbrush)
  • Distilled water (and a turkey baster)

Step 1: Tip the battery on its edge:

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.

TIP – Consider a Watering System

Another good thing to have for your golf cart batteries is a watering system. Make sure you check the water level in your golf cart batteries monthly to make sure they are still saturated. ( always do this after your batteries are fully charged because if you check them and fill them before you charge them 100% you could over fill them and acid will leak out the top of the batteries while they charge and get all over your cart and in the garage or where ever you store the golf cart. Which is not good because battery acid will eat away at your concrete floor in the garage. Checkout Pete’s great deals on a new One point golf cart watering system to avoid over filling them and making a mess or getting battery acid on your cart, clothes or garage floor and do it with ease. ( In minutes – not an hour or more… weekends are meant to be spent with the family or watching the game not in the garage filling batteries… so get yours today!)
