Not Sure What You Have?

How to Identify Your Golf Cart Batteries

Before you call, take 60 seconds to look inside your battery compartment. Here's exactly what to look for — no experience needed.

1

First: Lift the seat and open your battery compartment

On most golf carts the batteries live under the seat or in a front compartment. You'll see a row of rectangular black or grey boxes with cables connecting them. That's your battery pack.

2

Count the batteries

Count every individual battery box in the compartment. Most carts have 4, 6, 7, or 8 batteries.

3

Count the caps on ONE battery

Look at the top of any single battery. You'll see round plastic caps in a row — these cover the cells inside. Count them.

Step 4 — Match what you see below
