I learn something new every day
I was recently told that "AA" Lithium cells were available, something I was not aware of. Sure enough, there they were in BigW, albeit at $4.73 each in a four pack compared to $1/$1.50 for same brand standard alkaline cells. It doesn't make clear the comparative life expectancy but indicates on a graph 4/5 times. They weigh about a third lighter than standard alkalines and have a shelf life in the case of those that I bought best before 2024! My thought is that in things like cameras they will have a very long life and because they are 1.5 volts would be better than re-chargeables.
