How to Replace a Golf Cart Battery

Changing golf cart batteries isn't complicated. Most cart designs allow for easy installation and replacement—as long as the manufacturer's instructions are followed. If the cart's batteries are connected in series, parallel or series/parallel, your replacement battery or batteries should be the same size, age and usage level as the companion batteries. If a pack of batteries has 50 or more cycles, do not replace one with a new battery. Either replace them all with new batteries or plug in a good used battery. Always handle batteries with care.

Wrench.

Distilled water.

Baking soda.

Post cleaner.

Goggles and acid-proof gloves.

Step 1: Open the battery compartment, usually found under the front end of the cart. Most golf carts are powered by a set of six batteries. Disconnect the negative cable, then the positive cable.

Step 2: Remove the battery brackets and pull out the battery.

Step 3: Use a solution of baking soda and water to clean the battery cables and clamps. Replace any frayed or broken cables. Clean and dry the battery compartment.

Step 4: Install the new battery in the same position as the old one. Keep the battery clear of the cables.

Step 5: Reconnect the positive cable to the positive terminal and the negative cable to the negative terminal. Coat the terminals with a thin layer of petroleum jelly or battery terminal anti-corrosion gel.

Check the date code to make sure your new battery really is new.

Charge batteries completely before using them the first time.

New batteries need to be cycled (discharged to 50 percent, then charged again) several times before reaching full capacity.

Most carts are similar, but all aren't built exactly alike. Always refer to the instructions that came with the cart.

The solution of water and baking soda will neutralize acid spills.

Wear acid-proof goggles and gloves while handling batteries. Remove all jewelry.

Work in a well-ventilated area. Do not smoke in the vicinity.

Do not use solvents or spray cleaners.
