Additional charger functionality
Temperature based voltage compensation
The charger automatically adjusts the charging
voltage to the correct level according to the
ambient temperature. The default ambient
temperature is 20°C. Voltage is reduced for
higher ambient temperatures and increased for
lower ambient temperatures. The correct amount
is ±0.03V/°C. Max temperature compensate
charging voltage is 15.3 V.
14.7V button
Some batteries require a higher charging voltage
than other batteries. If the 14.7V button is
activated the initial charging voltage will be 0.3V
higher than the standard level.
Before activating this button, the 14.7V charge
voltage requirement should be confirmed. If a
battery requires this higher charge voltage, it will
be described on the battery.
Power Supply mode
Some cars can lose important information and
settings if the battery is disconnected. This charger
can be used as a constant power supply during a
battery exchange.
To use this function, the charger will need a
parallel load to be able to keep the voltage during
battery exchange. If not, the charger will go into
Error Mode due to zero-current detection when the
battery is disconnected from the car.
