(2) Display timer
Counting the following time after starting to charge switches display from on/off to on.
Display timer: 30 m (foc = 3.41 kHz)
In trickle charge mode, this timer pauses to count. This timer resets counting to initialize before charge restarting, in
case the charge as counting or pausing stops because of the charge to the adapter mode or the temperature protection
mode.
