Golf carts, unlike most other types of vehicles, run on battery power alone with no engine support. All the driving done with a golf cart can take its toll on the batteries in them. After so many times of charging the batteries in a golf cart, they will eventually die. Installing new golf-cart batteries is fairly simple and required to keep your cart on the course.
Difficulty: Moderately Easy
Locate the battery compartment on your golf cart. Most models will have the battery compartment located somewhere near the front of the cart, but some will be located in the back.
Open the compartment. In many cases the lid will either pop off, or open on hinges.
Detach the battery brackets and all cables that are connected to the batteries.
Remove each one of the batteries. There are usually six individual batteries, but this can vary from model to model.
Install your new batteries one at a time, positioning them in the same places as the old batteries.
Attach the positive (red) and negative (black) cables to the proper terminals on the first of the new batteries. Add a layer of Vaseline to the terminals, which helps resist corrosion.
