I just bought what I was told is an aw battery but the aw is a black sticker with silver print.The battery its self is red with black writting that says IMR 18650 3.7V 2000mAh (7.4WH). Is the aw supposed to be printed on the batt or is it always a sticker. It doesn't say that its protected. I dont have the option to post pics (or I haven't figured it out) can someone please post a pic so I can compare?
