I've always used tap water and get several years life out of my batteries. I always charge as soon as i get home from a trip and i usually recharge before going again if the boat has been sitting for a week or more. I think the distilled water thing is overrated, their is not enough minerals in tap water to amount to much buildup, after all how much water do you actually add to a battery during it's lifespan?
