Voltage must be above 11.6v with the key on and engine off, while cranking voltage must not go below 9v, if it does your battery is discharged and the starter will not operate or operate slowly. A battery will not go dead being disconnected for 2 days, that takes months.
Use a voltmeter at the battery to test voltage, don't rely on the stock gauge.
