Always wear protective goggles and gloves when working with a battery.
Do not allow any of the liquid from a battery's cell to touch your skin or clothing, as the powerful acids can cause burns.
Battery maintenance is critical. An overheated lead-acid battery can actually explode.
Some battery chargers are designed to work with multiple brands and types of batteries. Check the list of compatible batteries before charging your golf cart.
Use only distilled water to fill batteries. Minerals in tap water damage the battery plate.
Always remove the plastic caps from each cell of the battery before charging; otherwise there can be a dangerous buildup of gases.
