They do, but it's pretty low.  Check out page 7 of this document :

One of the nice things about NiCd batteries is that the electrolyte 
concentration barely changes (if at all) from fully charged to totally 
flat. 
Unlike with lead batteries, you don't have to worry about making sure your 
stored NiCd batteries are fully charged before a -20 degree night.
