I am curious to the self-life of the charge with rechargeable lithiums and do they contain as much of a charge as standard lithiums?



I am guessing it had an alkaline battery? I only use lithiums in my Fenix E01 and they last almost a year with mostly daily use.

I don't know how long the shelf life is. I use the 14500 (AA sized) rechargeable lithiums in my single-AA sized flashlights (the ones that can take the higher voltage, that is). I use the light on my belt several times daily, probably averaging 5-10 minutes per day (usually in the middle brightness setting). A rechargeable lithium will last me several months. The other lithium-equipped single-AA sized flashlight I have sit unused for up to six months at a time and they're always fine when I do get around to using them or swap them out to use as my daily carry light. They last several months in use after sitting for those six months. Unscientific, but it doesn't seem to me that they lose much charge.

My wife's Fenix E01 did indeed have alkalines in it. You cannot use the higher voltage rechargeable lithiums in that light. Rechargeable NiMH are fine however. I don't use primary lithiums except for extremely long "not used" scenarios where I want them to work when I finally do need them. In my case, that means in firearm mounted weapons lights. Everywhere else I try to use rechargeables (except, unfortunately, in my wife's Fenix that got ruined by the alkaline battery - I forgot about that one).

I have found that kirkland AA's seem to be just a bit of a more snug fit in my mini-mag lights. I wonder if the AA's size is actually a larger diameter than std. duracell AA?

I have used Energizer AA Lithium primaries in all three of our Fenix EO1s, for a couple of years. No problem to date.

I've been using Envelops and Energizer Lithium AA's for many years. Never had any problems, no leakage. Eneloops are durable workhorses. I even use them in my glove box flashlight. The oldest Eneloops get used in slow drain devices like remotes and clocks.

IMHO,alkalines are not only leaky, but obsolete. Eneloops and an occasional primary lithium works for me.
