you get to have a pleasant conversation with a customer support representative who refutes your claim on the grounds that the

batter was designed to never run out and it must be user error on your part. Reboot and try again.

lol, great. I guess I won't have to worry for a long time anyway. I don't really get how it works though.. its not connected to the internet

or Blizzards servers.. it seems like it just generates a number at random, so I don't see how the servers can possibly know what a battery

operated device is generating

by

I'm guessing it involves the use of satellite technology. Blizzard server generates a code every 60 seconds, beams to satellite, beams

to your authenticator.

The authenticator itself does not generate the code. Blizzard does..or their service provider.

I have a similar device for accessing work since I work from home. Those batteries last a long time.

and you've probably noticed it shuts itself off after a few seconds to conserve power.
