Battery sizes 16340 Cr123 etc Confusion

[spaceman41]

Hey there folks ,Im from United Kingdom and have purchased my first Laser ever! Its a Tesoar 1mw Military grade ( apparantley?) the description says it runs on 1x 16340 battery but I couldnt find one after some research Im still a bit baffled as to what battery to use as heard the ultrafire batteries arent great.Can I use a Cr123? its only 3v and this needs 3.6v? any help would be appreciated,many thanks Spaceman:thanks::thanks:

Hi Spaceman,
Go to eBay and get an AW 16340 cell there awesome That CR123 should work make sure you put the cell in the correct way, being 3V you may not get full power but it should activate the diode.Can't Hurt give it a shot When you say 1 mW do you mean 1W i'm sure you do.
Get you correct cells for it AW are great i have many with no problems. And get a good charger also a Nitecore charger in the Digital format is great They come in 2 cell and 4 cell units.They will be labeled 2D or 4D good price to ..

u need battery with 3,6v or 3,7v for it to work properly as said, 3v it might work but will be dim as its not meant to use those it needs more..
