Are these the same batteries mentioned in this CPF Thread?
I think so. But they do not give a "real" part number. However as far as I know there is only on energizer AAA lithium. So it must be it.
Very interesting to see the graph. Hopefully this extended service will be evident when I need to use them.
and in reply to the comment about cold weather operation with lithiums, everything I read says that they excel in cold. I have no idea why you see different results with your thermometer example. Guess that is what makes this all so intersting. Lots more to it than just reading the charts. The real world seems to have it's own idea of how things work.
