why do automotive batteries need water..?

Auto batteries need water because it is the electro-chemical reaction between the lead plates, and the acid, or "electrolyte" in the batteries that produces the voltage needed to start your car.

When electricity moves through water, it electrolyses it into hydrogen and oxygen. Over time, this depletes the amount of water that's in solution with the battery acid. This is why you occassionally need to top up a flooded lead acid battery with distilled water.

The water works with the lead & acid to create the charge that a battery has on it's own. It is a chemical reaction to all three.

Automotive bateries need deionised water which when an electric current is passed through it via electrolyte plates it becomes sulphuric acid. Maclaren.

That is the solution that completes the electrical circuit and transfers the electrons from the plates to the poles of the battery.

It gasses off little by little, over the life of the battery. Gotta put it back.
