I’ve got a great tool for topping off batteries. Attach a length of clear plastic hose to each end of a gas-line squeeze bulb. Next time you’ve got low distilled water levels, simply insert one end in the jug and squeeze. You’ll be able to control the amount of water going into each cell and keep from spilling and/or over-filling while pouring directly from the jug.
