Golf cart batteries can last from one to seven years depending on how they are used, maintained and charged. If you leave your cart in a hot garage without charging it, the batteries could be destroyed in a year. Whatever the reason for the demise of your batteries, when the time comes to replace them, you can save money by doing it yourself. Pay attention, however, to safety concerns: Always wear eye protection and gloves, and never smoke when working with batteries. Batteries can explode or catch on fire.
Things You'll Need
- Acid-safe gloves
- Battery carrier
- Insulated wrench
- Wire brush
- Plastic brush
- Baking-soda-and-water solution
Locate the negative terminal on the battery and loosen the clamp. Remove the negative cable first. Remove the positive cable in the same way. Be sure the cables do not touch each other, any other cable or the battery terminals.
Remove the brace that holds the battery in place.
Lift the battery out using two battery carrier straps (available at any auto supply store).
Remove corrosion on the battery rack and clamps using a wire brush (metal surfaces) or plastic brush (plastic surfaces). Neutralize the acid with a 10:1 solution of baking soda and water.
Place the new battery on the rack using the carrier. Replace the brackets that hold the battery in place.
Connect the positive cable to the battery terminal first, then the negative cable. Pay attention to the polarity of the terminals; never confuse the positive and negative cables.
Tips & Warnings
- Wrap wrenches with vinyl tape to prevent a dropped wrench from shorting out a battery.
- Never lay a wrench across the battery terminals. Doing so could cause an arc and result in an explosion or fire. Always wear eye protection when working with batteries.
