Lol... Is this a quiz question?
You can state that some battery chemistries are more likely to have a higher or lower continuous discharge rating than others .... But there's no such thing as an average. The basic ICR 18650s of Samsung and LG are sold by the thousands as battery packs for laptops and other appliances. Average of what? vape batteries ... All batteries ... ?

I don't quite understand what you mean. I've read several articles that state that the average c-rating of an IMR is 8-10c. I was just wondering if that average would apply to different battery chemistries as well. I do understand it can vary greatly, but surely there is an average.
It all depends on the manufacturer and how they make the battery, one of them is actual chemistry does affect the C rating. ICR for instance are commonly very very low in the 2 to 8amp CDR rating, this makes their actual C rating very low. IMR/INR do in fact have higher C ratings thus have higher CDR than ICR, generally in the 15 to 30amp CDR range. FE and LiPo it is all in their construction or assembly, for instance the Evic VT with the internal LiPo pack there are 3 cells in the pack wired in parallel to handle high amp load an individual LiPo cell can't handle, the mod manufacturers generally calculate very well what is needed with an internal LiPo pack. Still, though I do use a few ICR cells in my very, very low end output devices (Innokin SVD 1.0 and SVD 2.0 for instance) I use Panasonic NCR18650B ICRs in them as I rarely am above 10watts on these devices, 15plus watts I use IMR/INR chemistry batteries, so if you are not a battery geek I suggest do not even look at ICR, FE batteries and use only IMR/INR batteries, if you have a mod with an internal LiPo pack treat it with care during charging (trickle charge only don't rapid charge 0.5amps or lower charge current 4.2v charging voltage).
Thank you very much for your info. The last sentence brings me another concern however. There is a DNA 200 out there I was looking at buying that has zip charging. Is this a bad choice considering it uses a lipo pack?
It would depend on how the charging circuit was engineered and what battery/battery pack they engineer for it. Even with an Efest or Xtar with a rapid charge mode for 18650 batteries, if you constantly rapid charge a battery you decrease its longevity, rapid charging creates more internal heat than regular or trickle charging does, heat damages batteries, lowering their longevity in the long run.
Sorry was not intending to be rude ...
Even if you were able to calculate such an average taking all IMRs into acounts (might be possible since IMRs are fewer about) what would that give you? Looking at ICRs, there must be 100s of type ICR batteries around. Some have a 0.5C rating others a 3C rating. What's the average of all of these going to add to that as information? Just check if the C-rating of the battery you want to buy matches your intended use.
I don't care what is average, I care what is by my face. I'm using an AW 18650 3000mah with a 20A rating. I don't go up to 20A now but nice to know what I can do.
