(OP)
Does anyone know the shelf life of a AA Battery. How soon does the battery start to degrade? How long before it is out of spec?
Thanks

RE: AA Batteries
You don't mention the construction of the battery. That's the governing factor. Rules of thumb:
Carbon 6 months
Alkaline 1 year
Mercury 1.5 years
Lithium 6 years
Nickel-Cadmium 2 weeks
Nickel-Hydride 2-4 days
Lithium Ion Ah...I don't know, they're too new.
Of course, we're assuming storage in ideal conditions. Cold helps some of these and hurts others for instance.
The shelf life is the time it takes to lose half the available power. The batteries will begin to degrade as soon as it's built. It also is non-linear. Some batteries lose a lot of power quickly then flaten out, and some hold for a long time and then just die.
If you want anything more specific than this, you have to check the manufacturers specifications for particular types.
