Distilled water is water that has virtually all of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean container, leaving most if not all solid contaminants behind.
The contaminants foul the plates inside battery's and leave clogging deposits in cooling systems.

Water will not conduct electricity, but if you add a catalyst it will. (this means that battery plates will short out sooner with use of impure water) also when you over charge a battery the boil off is pure water the other parts of acid stay in battery this, plus cost, is why you use distilled water to top off a used battery instead of refilling with acid. This is the best summary I can give of a lecture that my Chem Prof (Dr. John Smith no siht his real name) gave on this subject about 20 yrs ago.

thanks. learned something new. i knew how distilled water was different... just didn't know how it mattered.
