The battery in the mecarmy x3 is (or states on the label) 100mAh.
Might get a few more of these if poss.
Up until AWT and Aspire, the general consensus was to just buy AW 16340 ICR/IMRs, because they were culled and of 'better' quality versus the other Chinese dreck out there. With the 10180s, I'd just buy a few of them and don't worry about eeking the last few cycles out of them. Discharge the spares down to 3.7v, stick them in a Ziplock baggie and then put them into the fridge.
70mAh, 90mAh, or 100mAh, the numbers aren't to be trusted, so don't rack your brain over it and buy on price and dealer.
It's not like there's a better tasting brand of poop out there.
