I previously posted a reply to this question from memory here is the detailed 
answer after checking my files:

Approx 88apacity left after :
2 years        at 20C    OR
5    months  at 45C    OR 
1.8 months  at 60C    
As is normal for most batteries this is approximately  a factor of 2 
reduction for every increase in temperature of 10C. This is why **if you keep 
the cells dry*** it pays to store them in the refrigerator. Most 
refrigerators run about 5C so the 12apacity reduction after 2 years 
stretches out to about 6years, assuming elastomer seals etc stay intact. 
Temperature cycling in the refrigerator tends to cause lots of condensation 
so it may depend a bit on keeping them dry in a seled container with silica 
gel.
