The stated shelf life of Lithium batteries is generally stated to be 
10 years, but that was the conservative number that manufacturers 
felt comfortable with. Present thinking is that with decent 
treatment, they should be good for a lot longer; possibly 25 years. 
If you have dud batteries out of the package, it's a manufacturing 
defect.
