–  Press the START/STOP button twice.
–  Keep pressing the „Up“↑ or „Down“↓ button until a new charging begins.
3 - The charger does not recognize any Battery -A- if the voltage is lower than 2 V:
The information on the display remains unaltered:
The type of Battery -A- and the amperes/hour (Ah) set are displayed.
Finalizing Battery -A- charging:
–  Press the START/STOP button.
–  Disconnect the black charging terminal „-“ from the charger of the negative pole of the Battery -A-.
