RebuswindI use my rechargeable AAA batteries exclusively, you should be fine. Lithium should last a long time on a single charge, but they're expensive so save them for camping or hurricane/emergency/zombie apocalypse.
Mario.PaulThanks, the reason I want to use lithium is due the the normal alkaline battery will leak over time and damage the light, and the leak proofed alkaline is as expensive as a lithium one. Do you know if this will handle a 10440 li-ion 3.7v? will the lumin go up to 300+ or will it just simply burn the light?
RebuswindI don't think it can take that monster safely but don't quote me.
That's a good reason to use lithium, I didn't know that was a feature of them. I can't count how many electronics I've lost to crappy alkaline batteries (including Duraleak).
The_GrizzLithium Primaries L92 (Energizer e2) are 1.5V nominal. Lithium Ion 10440 (Trustfire, AW, eFest) are between 3.2-3.7V nominal depending on chemistry. They were talking about 2 different types interchangeably.
L92 at 1.5V is fine. 10440 at >3V is probably too much.
The_Grizzit is about the voltage not the size....10440 is much higher voltage(3.7v). he is telling me don't use the lithium ion, not lithium Primaries aaa
RebuswindI understand now. Didn’t realize there was a “AAA” battery that came in a different voltage. Guess I’ll probably stick with Duracell lithium or Nmh rechargeable for mine
RebuswindI have the brass CREE version of this light and I put a 10440 3.7v LI-ion in it and the light definitely opens up, BUT it doesn't act correctly... The light only switches off if you have it on the high setting for about 30 seconds until its noticeably warm to the touch. Also, it doesn't cycle though the intensities like it should.
It works.
I don't recommend.
