Can I use a 3.6V Li-ion AAA with my UltraFire W-602C? Thought I read somewhere that I could. Done the searches, but can't find the definitive answer.
My UltraFire is useless with alkalines or Ni-MH since it won't restart after even just a few minutes of use.
Also, how do you protect the 3.6V batt since the light isn't going to cut out until 1.2?V?
