ged before. If the battery had been discharged with high currency then there
will be in the beginning of the charging a high current (max. 0.3A), which de-
creases after a short period. This means that with rising voltage the charging
current decreases. The following diagram shows this behavior:
For the charging itself it is not important if the battery is partly or completely
discharged. The battery can stay connected to the charger for a long period,
the surrounding temperature should be in the range of 10°C to 25°C. In case
the battery has been connected to the charger with the wrong polarity then
this will be indicated through a red light („verpolt"). Disconnect the battery
from the charger immediately.
