How to Connect Electric Golf Cart Batteries

By Jackson Lewis

Golf carts have two types of propulsion methods: gas power and electric. Electric golf carts make use of a bank of lead-acid batteries that run an electric motor. They are made to run throughout the day and be re-charged each evening. Newer electric golf carts are designed to be "plugged-in" in between uses. Electric golf carts are cheaper to run than the gasoline-driven version. A common task for an electric golf-cart owner is connecting the batteries.


Difficulty: Moderate
Step 1
Check the level of water in each battery before charging. The water should cover the leaded plates inside of the battery and be refilled before connecting to the charger. If you notice the water has starting to pour out of the top of the battery during the charge, the level likely has fallen below the leaded plates.
Step 2
Clean the upper part of each battery before re-installing. Refined or distilled water should be used. All dirt and dust should be removed in order to prevent intrusion into the inside of the battery during operation or charging.
Step 3
Conduct a visual inspection of the battery cables and posts. Replace frayed or fractured cables immediately and re-attach with petroleum jelly.
Step 4
Secure water vent lids on all batteries. The lids should be hand tight and secure.
Step 5
Connect your batteries one at a time to the golf cart. First connect the ground wire of a single battery (the black cable), followed by the positive cable (red wire). Then, continue with each of the golf cart batteries until all are re-connected.
Step 6
Operationally test your golf cart by driving a short distance from your work area to ensure you have the expected speed from the battery charging. This helps test all battery connections that were made.

Tips & Warnings

Check the water level in your batteries no less than once a week.
Avoid using mineral water to fill golf cart batteries.
