For Christmas, my lovely bride bought me a Nitecore P12.
With it came a pair of Ultrafire 18650s. I don't know ANYTHING about 18650s except for they are all the craze now.
These batts are yellow in color with red stripes and say BRC 18650 4200 mAh, 3.7v Li-ion on the side.
Are these safe to use in this Nitecore? I do understand that the 18650 is basically a measurement and that Li-ion stands for Lithium Ion, but what does mAh and 4200 mean? Also, are all 18650s 3.7 volts?
Like I said...I don't know beans about 18650s. Somebody please school me! :thinking:
