Folks:

I was wondering if anyone had any knowledge or reading materials they could recommend regrading battery clips.

Our scenario is this:

The project uses a AA or D lithium battery that is to be dropped in to a battery holder. The circuit will draw about 5ua most of the time but intermittantly draw 50mA. The PCB will be housed, but will be used outside, and won't be sealed. I am worried about the battery/holder becoming intermittant, and resetting the processor. I realize the battery metal should be as closes to the type on the socket clips to reduce galvanic effects. I also thought about using dielectric grease on the battery contacts to keep weather out. Any advice, concerns or studies done on that subject?

Anything outside tends to corrode. To slow the process, place the battery holder in a plastic case with a lid that screws down. Run the leads out a small hole and seal it with hot glue. Don't use silicone glue, as the fumes are acidic and will cause problems.
