You know I have something that's been bugging me here and really don't have a complete solution here. Maybe I can get a suggestion. I have a 36 plate dry cell with a 3qt. reservoir. When I go on a say a 200 mile trip., I'm always having to add water to it. And If I go a week out and about, I still have the same problem. I don't have leaks anywhere. I often wonder if water is getting sucked into my intake, but it's not. Does the water evaporate, any body? I'm stumped.
