All of a golf cart's batteries do not have to be changed at the same time, but running an old battery with a fresh one will not be as efficient as running all new batteries. Experts advise golf cart owners to replace all batteries if more than one is dead.
Most golf carts use between four and six batteries, each of which is required for operation of the cart. When one battery dies, the golf cart will not start or run, so that battery must be replaced.
The procedure for replacing one or more golf cart batteries varies based on the manufacturer. In most models, the batteries are installed on metal plates underneath the front bench.
Other problems can render a battery useless, such as failing to refill the battery cells on a daily basis. Golf carts require water to recharge when they are plugged in. Additionally, if batteries are run down completely before they are recharged, they might not last as long.
If a battery is overcharged or overheated, it can catch fire or explode. Proper battery maintenance is essential for safe operation, so it is important for users to read their owners' manuals and understand how their golf carts operate. Replacing an old or defective battery (or a set of batteries) can prevent serious injuries.
