During the charging procedure, the three green LEDs light up
one after the other and briefly go out. The battery is fully
charged when the three green LEDs light up continuously. The
three LEDs go out again approx. 5 minutes after the battery
has been fully charged.
Temperature Control Indicator
The red LED signals that the battery or the electronics of the
garden product (with battery inserted) are not within the op-
timum temperature range. When this occurs the garden prod-
uct will not operate or not at full capacity.
Temperature Control of the Battery
The red LED flashes when you press the button or the On/Off
switch (with battery inserted): The battery is outside of the
permitted operating temperature range.
The battery switches off at a temperature above 70 °C until
the optimum temperature range is reached again.
