Re: cache battery expiration

[DrFranken <midrange@xxxxxxxxxxxx>]

You say 520 but didn't say where in the 520. It's possible that if the 
battery was not disconnected  for the requisite 2-minutes that it did 
NOT reset and therefore the timer kept counting. Now you've got a 'dead' 
battery.

Since he needs to redo the process in order to correct the issue, make 
him bring a new battery too!
