Why distilled water is used in car batteries?

Distilled water is typically used in batteries (Automotive/Telecommunictions etc.) due to it's lack of mineral content and general purity. Using tap water in wet cells can create problems in the long term as minerals can form on the cell plates and affect the efficiency of the production of electricity. In addition, soft water is generally not accepted as a substitute, because of the salt content from the process. (Same problem...deposits on the plates) Using distilled water increases the life of the wet cell....stick to distilled water as a first choice!...Cheers!
