No, they just are marked that because they meet the dimensions set out by the IEC for the battery, which has a set of dimensions with a tolerance, and a very broad range of capacities, though they should meet the "typical" capacity spec, but that is not guaranteed.

find this from: wikipedia
RCR2: Substitute for CR2 primary lithium. Nominal voltage usually is 3 V.
