Battery_charging_percentage_notifier

Python program to notify user to start charging or stop charging laptop battery

The python program is designed to create a message box when the battery of the user needs charging, or when the user must stop charging. This can help to limit capacity performance losing of the battery over time.

In general lithium ion batteries charge state should remain between 20-80 percent charge state for optimal battery life span.

The given code example will notify the user when the battery charge state if lower or equal to 25 percent, or when the charging state is higher or equal to 90 percent.

A message box is used for the notification. The message box will disappear when the user closes the message box, or when a battery charging state change is encountered (i.e. from charging to discharging or vice versa). Furthermore, the battery percentage as well the charging state are printed to a console.
