Looking for an odorless 12volt battery?

Question

working on a deer hunting project, and trying to find a battery that wont put off a strong scent that would scare away the animals... any ideas.

Answer 1

I use game cameras all the time and I have no problems with the smell!*

Answer 2

You got more to worry about from a flash or poorly directed camera than you do a battery. All of them are going to make a smell that animals can detect.

If you are that worried, then put it downwind of the target.
