Program selection

NOTES
► If a battery is detected in the voltage range of
between 3.7–7.3 V, the programmes 2–3–4
can be selected. The charging process takes
place automatically. Depending on the selected
program, the characteristic charge curve is
monitored for voltage, time and temperature.
Included are the diagnostics program, revitalis-
ing mode and retention charge.

Retention charge

As described under programmes, this appliance
features the automatic retention charge. Depending
on the voltage drop of the battery, caused by
selfdischarge, the appliance reacts with diff erent
charge currents.
The battery can remain connected to the charger
for longer periods of time.

Appliance protection function

The charger switches the electronics off and switches
the system instantly to the basic setting, as soon as
there is an abnormal situation, such as short circuit,
critical voltage drop during charging, broken circuit
or swapped connection of the connector clamps is
detected.
Should the appliance become too hot during charg-
ing, the output current is automatically reduced. This
protects the appliance from damage.
