How it works
The laptop will run the stress-test in a loop until it runs out of power. For every minute the laptop is on during battery testing, a line of text is logged in a file called bat_mon. When battery test is run again, the script counts up the number of lines of text in the bat_mon file, and outputs the number as the number of minutes the battery lasted.
