being discharged.

the batteries are receiving a high recharge voltage for fast charging from
the power supply.
’charging’:
the batteries are only receiving a maintenance charge.
’On USB power’:
Active Braille is connected via USB with the PC. There is no charging or
discharging of the batteries. The power is provided by the USB interface.
