The point of my post is that Arizer batteries are not seconds or culls or underweight, IMR, I'm not sure, but prima facie evidence indicates some of their batteries are not equal.
My experience informs me Arizer is laying specs down for the batteries they'll accept from a vendor.
And IMR does not seem as picky.
Agreed, that's what I 'took away' from it anyway.
IMR (whom I use a lot, along with Orbatronics) has no direct source of the genuine article. They buy what they think/hope is not counterfeit but mistakes happen and crooks are looking for openings. You can be sure Panasonic never allowed a sub standard cell 'out the door' with deceptive labeling, but spending a little time searching the net turns up tales of very good fakes. You have to buy from trusted sources and even be willing to test what you buy (which I also do a far bit of the time, testers are cheap and accurate) sometimes.
I use a lot (couple dozen?) NCR18650Bs in various applications. They are current 'state of the art' for capacity while still providing reasonable current ability (4.8 Amps continuous) for most things. Devices needing more current get different 'batteries' (cells) at the expense of run time (always a trade off).
I could, of course, get a lame one next time from IMR, but so far........
I suspect Arizer also tests before sales, probably not every piece of course, but a statistically significant sample of each shipment.......they have a lot at stake. A batch of weak 18650s sent out in a production run could be extremely expensive to replace?
Fortunately the average Air owner only needs a few spares? The extra few dollars buys peace of mind as well I think. Not a good place to 'go cheap'.
Regards to all.
