Just a word of advice: If you're referring to the MK IIx, I use the Ultrafire 3.6V unprotected cells. The Ultrafire protected 14500 cells don't work well in the MK IIx. Some of the modes don't work properly and it's just "flakey".
I have some AW 14500 cells on the way, which I've heard great things about, so I'm looking forward to trying those in the MK IIx.
ya know that light (acting that way) could be going into overdrive above the VF of the led , meaning it has a boost curcuit, and expects a 3.3V type of battery, not a fully charged 4.2V type of battery.
i dont KNOW about that exact model, but it would be very common for that to occur, REGUARDLESS of the stuff in the "sales" and advertising.
-------------------------------------------
also , like fenix said, i dont know of any raw li-ion cells sold at rat shack, they might have some li-poly stuff for RC, like 11v type packs , so i would Suspect that it might be a primary, and surely wouldnt Charge it
untill i know for sure.
they do have other "pack batteries" with li-ion in them, but no specialty li-ions yet.

THAT, is a computer backup battery, and is a low current 10 year type of primary cell, if its that ,
DONT CHARGE IT and you will waste it in a high powered light.
at the rat it says this, """"
Rechargeable Yes"" <-- spec quotes, not correct
but i am almost positive a LS is a Primary, and would explode
if recharged. Learn before you burn.

--------------------------
the difference is usually in thier referances
LITHIUM - almost always refers to a Primary throwaway cell - recharge bad
li-ION - usually refers to some sort of rechargable
li-Fe and Li-Fe-Po refers to the newer safer rechargable li-ion technology with lower capacity.
---------------------------
there is a way to snag a li-ion "AA" sized battery from the RS, its in a RCR-v3 (SP) type of digital camera pack which has in it 2x shorter than AA li-ion rechargable cells. i forget the exact name of the pack, but that is how we aquired our first 2 AA li-ion rechargables, long before they were even sold. its not the LITHIUM one, its the rechargable li-ion one.
