Hi!
Which method should I use to know:

first time i ran and the device wasn't running yet
the battery on the device is low or even missing
Some libraries have the method "isrunning" or "lostPower"...

Thanks

For the 1) question: check year, if it is 00, it was powered for the first time:

DateTime MyTimestamp;
  MyTimestamp = Clock.read();
  if (MyTimestamp.Year==00) {
    Clock.promptForTimeAndDate(Serial);
  } else {  
    Serial.print(F(" * RTC time: "));
    Clock.printTo(Serial);  
  }
