I think that's backwards.  The battery is only used when there is no power to 
the GPS module.

AAs are roughly 2800 mA hours.  There are 8760 hours in a year.  That's 319 
microamp years.  (How's that for a SI unit?)  So that's 3 years if your GPS 
module takes 100 uA.  I think that's way high.  Anybody measured it?  There 
is probably a strong temperature component.
