The batteries are one of the most important components on an electric golf cart.  Taking good care of your golf cart batteries will help them hold a charge better, last longer, and avoid expensive golf cart repairs.  Replacing a set of golf cart batteries costs several hundred dollars so it makes sense to follow good maintenance habits and maximize the life of the batteries.

Golf cart batteries need more care and maintenance than your car battery because larger demands are placed on them.  Unlike the engine starting battery in your car which is kept almost fully charged by the alternator, golf cart batteries are used until they are deeply discharged before recharging them.  This discharging and recharging cycle is hard on a battery.

The basics of golf cart battery maintenance are cleaning, watering, and charging.  When performing any maintenance on your golf cart batteries, be sure to wear appropriate protective gear to protect your eyes, skin, and clothing.  Also, golf cart batteries give off hydrogen gas so no smoking and avoid sparks while maintaining your batteries.

Golf cart batteries should be charged after every use.  Avoid discharging the batteries completely and always charge the battery fully.  Regularly undercharging or overcharging the batteries will shorten their life.

Once a month, clean the batteries and check the water level.  The water level in each cell should be checked and distilled water added to bring it up to the proper level.  Always add water after the battery is fully charged and don’t overwater.

Make sure the caps are tight, then clean the batteries using a solution of 1/4 cup of baking soda and 1 1/2 gallons of water.  Spray the mixture on the batteries and let it sit for about five minutes.  Rinse with fresh water and dry the batteries with a clean rag.  Avoid spraying water directly on any electrical components.
