If you have detailed questions on the battery specifications
please contact the battery manufacturer.
The voltage of the battery does not increase after the charger
has been connected and put into operation.
Use a suitable multimeter to check whether the voltage of the
battery terminals increases during charging.
Check whether the terminals are connected properly to the bat-
tery terminals.
Clean the battery terminals.
The battery is not completely charged after charging for
approximately 20 hours.
Disconnect the charger from the mains power.
Remove the charger terminals from the battery and wait for a
few minutes.
Use a suitable multimeter to check the voltage of the battery
terminals.
If the multimeter displays a voltage of 10 V or below, this means
that the battery is defective and can not be charged.
Have the battery checked by a specialist or dispose of the bat-
tery in a suitable manner.
The battery discharges itself after a short time if it is not used.
Use a suitable multimeter to check the voltage of the battery
terminals.
If the multimeter displays a voltage below 12 V, the battery is too
weak to be able to remain charged.
Have the battery checked by a specialist or dispose of the bat-
tery.
