Batteries. Did we give you cold chills? Most golf cart owners hate to hear that word. These are by far the most expensive thing you can buy for a golf cart. The frame and body cost less. You want to make sure you do everything you can to keep the batteries in the best condition for as long as possible. At the very best, you will spend over a grand to replace the pack and one battery at a time is never a good policy. Having a Battery Water Filler Bottle on hand is one of the many things needed to ensure your power source is adequately maintained. Keeping them fully charged at all times is the best defense, but dry batteries never helped anyone's case.This golf cart water fill bottle has a cap that meters the fill rate. As soon as the cell is full, water stops flowing. This prevents overfilling and spilling battery acid onto the garage floor.

Tap water can shorten the life of golf cart batteries, depending on mineral content.
