Looking for a moose of a battery that will last almost forever in a glove box or bug out bag? This is it!
They will still have plenty of juice in a decade and I have never, yes never, lost a flashlight to battery leakage from one of these things. If you have need of a stash of emergency batteries, pack these guys away. They will be ready when you need them.

Is it true that one advantage to Lithium batteries is they do not leak like regular Alkaline batteries?

Alkaline batteries shouldn't leak either, but yes, lithium batteries generally have a lower leak rate due to the chemistry.
