When I put water in the golf cart batteries there are 18 or 24 1 inch holes that need a controlled fill. I use an awl to poke a hole in the cap of many plastic water bottles (16oz) and just point and squeeze. Using a flashlight with the other hand helps illuminate the water level in the hole. This makes quick and easy work of the task.
With the price of bottled water, this is cheaper and more convenient.
