The car battery works in a golf cart, but they do not last as long or stay charged up. So make sure your next battery is marine or deep cycle.

Gas carts use starter batteries, at least that is what my Yamaha is spec'd for. The battery runs the generator to turn the engine and cause it to start. Once started and moving, the generator charges the battery. There seems to be no need for a deep cycle battery except for the possible case of many holes of golf with short distance between holes where there are many starts in a short distance traveled. Still, as mentioned, my Yamaha manual specifies a starter battery.
Electric carts with lead acid batteries most likely benefit from deep cycle batteries. In an electric cart the batteries are regularly discharged and recharged which is not normal for a starter battery. The deep cycle battery is designed for this type of use.
Electric carts with lithium batteries don't have lead acid batteries at all. Many lithium carts come with an eight year warranty on the battery. I can't find the year lithium carts first came out so there might be few or none that have reached their eighth year yet. I have not yet read of any carts needing a replacement battery whether under warranty or otherwise.
