However, the wrapping can tear and expose the internal components of the cell, which are volatile if they come in contact with any other type of metal, from coins and keys to other batteries and vape accessories.

    Umm, you got the numbering system a bit wrong. The first 2 digits are indeed the diameter in millimeters but the remaining 3 digits are NOT the length as you explained it. The length is the following 3 digits are length in tenths of a millimeter. Think about it… 650mm is friggin 25 inches!! In reality an 18650 is 18mm dia 65.0mm len.

    Thanks for taking the time to present this info. Your descriptions of the terms helped and were logical and easy to understand. That said it is confusing to use your explanations, look at the battery specs and understand why several of the batterys with superior specs are listed low on the list. Any chance you could explain for us?

    I’m new to vaping and thinking of buying a smok mag 225 watt kit. I have some Sony vtc6 flat top batteries and some Panasonic NCR18650B which is button top. I think they are both around 3000 to 3500 mah batteries. I didn’t want to have to buy more batteries if the ones I have will work. I want a battery that will last for a long time and to get the best vaping experience. If there is a better battery for vaping with this smok mag kit than the ones I have I don’t mind buying more because I use the ones I have in flashlights anyway. I just want to get the best vaping experience and would greatly appreciate any help that you could give me. Thanks in advance and this was a great post

      I actually just bought 2 2packs from Vape wild. They seem like a tough battery. They are NOT what I needed though. I needed 18650 not 21700. I paid $24.00 a pack for a total of 48.00 I just wish they were the correct size.
