I want to put a very large clock on this wall, (just outside of the patio door) but with my zone 5ish winters not sure if I can leave it out all year like I want to. I can see this from my kitchen, dining, patio area and from much of the garden where I work so I'd really like a clock here. Is there a special kind of battery that doesn't freeze, I assume most clocks run on AA or thereabouts. Suggestions welcome please!
