For interest, the prefix refers to the chemistry and the numbers describe the nominal dimensions in mm.
So:
ML = Manganese Lithium (rechargeable) (3V)
MT = Manganese titanium lithium (rechargeable) (1.5V)
and 621 = 6.8mm diam x 2.1mm thick.
This system is reasonably consistent for coin cells from all but US manufactures.
