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 25°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
Keep pressing the button until the LED shines one
by one in a regular buttom to the top cycle, the
charger will start power supply mode. In this mode,
the charger supply 13.6V.
If the output short circuit or connect with incorrect
polarity in this mode, the charger will go into error
mode. You should press the power button to turn
off the charger, then restart the charger (go to
charger or power supply mode).

Automatic restart after power interruption
If the mains' power supply is temporarily interrupted,
