Preparation
In contrast to Ni-Cd or Ni-MH batteries Lithium-ion batteries do not have a
memory effect. The capacity of other batteries decreases steadily but the capacity
of Lithium-ion batteries does not decrease. The capacity remains constant until
the electronics interrupt discharging. The motor will stop abruptly, if the charging
level of the battery falls below a certain value.
Regardless of the charging condition, the battery can be charged at any time
without damaging the cells.
1. Connect the charger with a wall socket. The LED on the charger turns on red
and indicates that mains voltage is connected. Now connect the battery with
the charger. The
red
charging LED on the battery turns on and indicates that
the battery is charged.
2. After charging process (approx. 2 hours) the red charging LED turns off and
the
green
charging LED turns on. Remove the battery from the charger and
unplug the power cord from the wall socket.
Hints:
The electronics protects the battery from over-charging, over-heating and total
discharge. There is no loss of charge. The battery is characterised by low self-
discharge. A fully charged battery is always ready for use, even if you do not use
it for months.
A battery that is new or has not been used for a longer period does not develop
its full capacity until after approx. 5 charging/discharging cycles. When properly
using the battery it can be charged up to 1000 times.
If you notice during operation that the motor stops abruptly, the battery is
discharged and should be re-charged.
We recommend ordering a second battery under the article no. 82 87 21 so will
be able to operate the garden set continuously.
Inserting the Battery into the Unit
1. Push the battery all the way into the
battery slot until the battery locks audibly.
2. For removing the battery press the
releasing button (1) down and pull out the
battery.
