Nest thermostat

[TequilaScotty]

I wish to install a nest at a cabin.  The HVAC has a c wire. 

Does the nest Have to have the triple a batteries?

I turn the heat off in winter, but go up occasionally and need the WiFi capability to turn the heat on before I get there. 

Batteries and minus 40 degrees don't mix. 

Thanks

Perhaps a little more clearly.  I know the batteries are for back up.  If power goes out do you lose WiFi settings?

The batteries are just for backup.  If you have a C wire then that will power the nest thermostat.  If the power goes out the reality is your wifi wouldn't be working anyways.  If the power is out for long enough the batteries will die, but would come back online once power is restored.
