becaue..they dont actually HAVE a capacity in tesame sense.

A rechargeable is generally rated at a 10 hour discharge rate: with
decent cells that capacity is broadly constant across anything from 10
minutes to about 100 hours. Dry cells are not like that. They rapidly
polarize under high currents, but then 'recover' if left alone.

If you look in the technical data on the manufacturers sites you will
find mAh data.
