Did anyone experience battery degradation in rain. I saw about 40 percent degradation in rain. The car going on AP at 70mph for the most part. With wipers on high. Oh yeah and the auto wiper isn't good at all. Needs a lot of work still. It got me worried. I started at 140mi battery and when I finished my 60mile drive the battery was at 38 miles. Same thing happened on the way back. It was showing 360 Watt hours/mile. Should I be worried?
