I have an Optimun battery mounted on the inside of the frame under the vehicle. There is a tray and sides on the battery box but the top of the battery is open with the terminals being exposed.
Do I have to worry about the battery 'shorting out' if rain or water hits the top of the battery?
Thanks

No you do not, you just have to worry about it going bad on it's own. I am on my third one, all replaced under warranty. Just in case you don't know, I think Optima batteries are highly over rated.

I agree with 302, I have a battery mounted under the passenger seat on my 56 Ford truck (original place for that battery). The battery merely sits in a tray mounted to the frame. I have never had a problem with the battery shorting out even going in puddles, rain etc. The battery will short out if you touch metal to both the pos. and neg.
I also agree with 302 on the Optima batteries. I have yet to have one last more than 2 years for me. They are guaranteed, but I'm tired of returning them. They are overrated!!!

Fresh water is not supposed to conduct well at all. Salt water conducts.
So rain should not give you any problem.

I just noticed you live in Minnesota.. I will assume they salt the roads their? (I don't know anything about that.)
Salt water does conduct electricity.
