Reconditioning Golf Cart Batteries is not the best way to extend its useful life
Most electric golf carts are equipped with 6-volt lead-acid batteries, which are small versions of car batteries. However, batteries in golf carts often don’t last as long as they could because of neglect and improper storage. And with using liquid acid to stay charged, golf cart batteries are sometimes easy for them to loose their power if not maintained properly or sit on a shelf long enough. But you can do several things to make a golf cart battery last longer, including reconditioning the batteries. You also can reduce problems by making sure all electrical devices on the cart are turned off when it is not in use.
Recondition lead-acid golf cart batteries to extend their useful life. Even with proper maintenance, the lead plates in a golf cart battery may become sulfated. This is relatively easy to remedy. Remove the battery as you would to charge it. Before charging, drain the fluid from the battery and replace it with a mixture of 12 percent to 15 percent magnesium sulfate (Epsom salts) and distilled water. Then recharge the battery. It should resume normal function, though you may have to recharge it a couple of times to bring it back to full storage capacity. Note that because the lead pates can suffer damage from the sulfation, reconditioning a battery won’t work more than a few times.
Anyway, the best important way to extend the lifespan of golf cart batteries is still care and maintenance which is often mentioned when buying a golf cart. Taking care of your battery, you did not need to recondition it. Always follow a manufacturer’s instructions for maintaining a golf cart battery. Then check to make sure that all vent caps are tight. Clean any dirt, fluids or corrosion from the top of the batteries with a cloth or soft-bristle brush and a solution of baking soda and water. Next, clean the battery terminals and the inside of the cable clamps with a post and clamp cleaner. Regularly testing golf cart batteries, and keeping them adequately recharged can prevent a breakdown before it occurs, saving both time and money.
