When charging, the peak detection circuitry will terminate the
charge automatically when the battery is fully charged.
Discharging will be terminated when the battery voltage has
fallen to 0.9v per cell, discharge beyond this point may
damage the battery and will not provide any further useful
power. The screen will display the capacity supplied by the
battery being discharged.
The SuperNova has two modes of operation, either automatic
or manual.
SJ has created this innovative auto charging/discharging
system. The charger will automatically detect and select the
most appropriate current level by checking the battery status
every minute during auto charging/discharging.
