Golf carts use "deep-cycle" batteries that are lead-based and designed to provide a sustained current to power the cart for a day. When not in use, golf cart batteries should be charged to ensure proper performance when used on the golf course. A common task for golf cart owners is hooking up golf cart batteries that have been removed from the golf cart.
Confirm that the water levels in each golf cart battery are filled with distilled water to, but not above, the fill line. Tighten the lid to each battery until it is hand tight.
Clean the connections of each battery terminal with mineral water if there is evidence of dirt or grime on the battery. Be sure to wear acid-resistant work gloves while doing this.
Place each battery in its respective cradle position in the golf cart battery chassis. Ensure that each battery is seated in the battery bracket so that it is sitting level.
Connect the positive red wire that is coming into the battery compartment with the first positive connection post on the battery.
Connect the ground wire from the battery in to the positive post on the subsequent battery. Repeat this process with each battery. From the final battery, connect the black cable coming into the battery compartment to the final negative post on the last battery in the bank.
