Carbon cells last two to five years, maybe. These are the
ones that say "Heavy Duty".

Carbon-zincs are a waste of money.

CY: Generaly, yes. They are good for giving away to other
people. And good for short term needs, like a flashlight you
only need for the weekend.

Alkalines last a lot longer than that. About six weeks
ago,
I opened a flashlight I bought 10 years ago. Mag light,
with
Energizer D cells. Unused, in the original package. Worked
fine.

alkalines are rated 5-7 yrs stored life.(retaining 85% of
their capacity)

CY: You mean, that the Mag light I stored for ten years is
now a 2.55 cell mag, instead of a 3 cell mag?

Lithium batteries are supposed to last even longer than
that.

Lithium are rated for 10 yr stored life.

CY: And how much capacity at the end of the decade?




IIRC,90%.
Lithiums also operate in a wider temp range.(like cold temps,where one
might want to take pics with their camera and alkalines would be affected)
