Some of the crap unmarked ones definitely

There are some interesting graphs that show that the (standard) CR2032
actually has a capacity of 210mAh - if the current draw is around 0.03mA
or less...
It's down to 100mAh at 0degC and a draw of 100mA, which is still
reasonable really, given its small size.
