Originally posted by clmonk I find it amazing that everybody wants extra batteries. Perhaps it's that I don't shoot 600-800 shots at an outing, but honestly, my battery lasts so long that I have NEVER had it drain out on a day shoot. I HAVE an extra that I bought at Batteries Plus, but I have never had to switch it out on a shoot. But in answer to your question, No, batteries seem to be in plentiful supply.
I don't find it amazing that people want spare batteries. When one is out taking Christmas lights in Sparwood, BC, 4,000 feet up in the Rocky Mountains in late December, one needs as much battery power as one can carry. -20 C (-4 F) kills batteries in short order with the cold. Keep swapping with the one in the shirt pocket, and you can keep going long enough to finish the shoot. They recover when warm, as long as you don't flatten them right out.
