How do I tell the CDR of a rewrapped battery.

Before I started being interested in mechs I had rewrapped my collection of batteries.

How do I find the CDR of a battery if it has been wrapped. Do I need to purchase new batteries for mechs?

I have mostly Fogstar batteries but cannot find Fogstar CDR's for 18650s or 21700s in the battery tables I have found.
