The "AA Battery Tester Lite" is an application that gives you the ability to check whether an AA type battery is charged or at least is in good condition. This application takes advantage of the electromagnetic field of the battery but also the ability of the magnetic sensor. There are two battery control modes:
1) After you click "reset" and then "set value" to adjust the application to the intimate setting, touching the battery on the mobile screen like the showing photo. Move it across the screen until you receive the maximum mark on the control bar. If the battery is charged and in good standing will receive the indication on the display "BATTERY IS ok !!! ".
2) Short-circuited with a short cable the poles of the battery and repeat the above method (this method has better results because the field is stronger).
