I am going to need a 18650 3.6 volt rechargable battery and do not have one for an O-like 250-300mw green laser module and need to know what size in mm is the diameter of the battery and the total length of it. If you know please send me a reply back, also the highest charge it will hold is 4.2 volts right and not higher? I don't want to ruin the module. THANKS.
