So, I guess, for me, misleading specs that kind of over promise and under deliver are bad, because (understandably) people are expecting really high capacity. Instead of misleading people to try and sell the product, list the specs like anything else, and let people decide.
I guess "relatively poor" would have been a better statement, which better reflects that the companies are under delivering the capacity they're implying.
From what I'd seen, they post the 1.5V cells in mWh, versus the normal mAh. mWh/V = mAh.
The tricky part is that these output 1.5V, but they're normal 3.7V Li-ion cells. If that's calculated at 1.5V, it's pretty crazy capacity, while if it's at 3.7-4.2V, it's okay (about a typical 14500). Some of the testing I saw showed them outputting what appeared to be closer to the lower end of that range (which means mAh is likely calculated with the higher voltage). So, it seems like they're switching to mWh so people will calculate them out to some monster capacity, only to end up with a capacity similar to a 14500.
This is a decent video where he looks at the Xtar ones:
There was another one (with a different brand...EBL?) I remember watching that talked more about capacity, but that was at work on lunch, so I can't find it, now, haha. There is another one somewhere, too, and they disassemble the...Xtar ones. That was kind of neat, as IIRC, the circuit was surprisingly compact.
I think if they had really impressive capacity, they wouldn't use a different metric, so that means I tend to assume these are going to be on the lower end of a 14500 capacity (since it's just a 14500 with a circuit), and then sprinkle in some marketing magic.
