Distilled Water For Wet Cell RV Batteries

[GypsyCliff]

Ok fellas,

So, I go to the auto parts store to get new wiper blades for the coach just in case; got 'em.

The salesman noticed that I had distilled water on my list so I asked him if they had it so we could put it in our batteries. He told me that the new (for the last 10 years) wet cell batteries should be tapped off with sulfuric acid instead of distilled water. So, I bought a container name "Battery Acid Water"; then promptly went to the grocery store and bought distilled water. I saved the receipt so that I could return the container of sulfuric acid. BTW, the box says it's sulfuric acid and water.

I'm not sure it's worth the $8.95 I paid for it or if it's really any better. The salesman's stated that by adding distilled water you dilute the electrolytes.

Need some advice,

Cliff
