Couple of Questions About Efest Batteries

[makeyourself]

I'm thinking of getting a couple of Efest IMR 3100mAh 20A Purples. Looking at the specs I'm just wondering what exactly it is that Efest mean by "Quick Discharge Current": Efest IMR 18650 battery 20A purple efest 18650 3100mah 3.7V rechargeable battery -Efest battery for E-cigs

At first I thought it must mean a pulsed discharge current of 20A and a continuous "Quick Discharge Current" of 2A (2000ma). But apart from being ridiculously low, this doesn't seem to make sense when you look at other Efest batteries like this one:
Efest factory 30amp 18650 battery Efest purple battery 2100mah 3.7V battery-Efest battery for E-cigs
That one also has a similar Quick Discharge Current of 3A but it is clearly stated on the battery label "Discharge current: 30A (60A can last for 75 seconds)".

So all I can conclude so far is that Quick Discharge Current is some sort of meaningless figure.

Ultimately I just want to be able to use the 20A Efest model with a sigelei 20W. I understand the current input limit for the Sigelei is about 8.5A so as long as I have some head room I'm happy.

I would go with the new sony vtc5 2600 mah 30a great battery at almost the same price vapordna has them 3 for $30

I'd go with something other than Efest batteries myself. Not to drag any battery manufacturer through the mud, but sometimes some of them deserve it.

Efest has a history of exaggerating their battery specs. Take for instance their purple Efest 18650 IMR 2500 mah battery. Efest states its a 35 amp battery, but remove the wrapper and you'll find a rebranded LG18650HE2 battery which LG (the manufacturer) says is only a 20 amp battery. Who you gonna believe? The manufacturer or the distributor who is just re-wrapping the original battery? 15 amps is a big figure to be missing when you are buying a battery specifically for sub-ohm vaping.

Efest 30 & 35 amp batteries

I don't have a problem with distributors who rebrand batteries as long as they are truthful about the specifications. AW and Orbtronics sell re-wrapped batteries made by Panasonic. They don't exaggerate their batteries specifications.

I'm not sure what Efest is referring to with the "quick discharge current" terminology. Again, Efest has a history of confusing or misrepresenting their battery specifications.

Yes I take your points on Efest, the fact that they state specifications such as "Quick Discharge Current" when 2A is blatantly not a quick discharge current in comparison to 20A is confusing at best. Also the only test that I have been able to find on the 3100mAh 20A version is this one:

It's in German so you'll have to use a browser that can translate it but the long and short of it seems to be that they think that its actually a 10A battery. Obviously this would appear to confirm some of the other concerns raised above.
