USE

14,7 BUTTON
Some batteries require a higher charging voltage than other batteries. If the 14.7V button is activated the maximum charge voltage will be 0.3V higher than the standard level. Always follow the battery manufacturers recommendation regarding charging voltage.

LI BUTTON
Pushing this button will activate the charging curve for Li-Ion batteries. The top charge voltage is 14,4V and float charge voltage is 13,5V. Temperaturecompensation is deactivated in this mode. In this mode the charger will output power even if a battery is not connected.

POWER SUPPLY MODE
When the charger is turned off the button can be pressed until the LED shines one by one in a regular bottom to the top cycle. The charger will be in power supply mode regardless of the battery voltage after it has been turned on, so it can be used to change the battery of the car without loosing car settings/data. In this mode, the charger supply 13.7V and max 35 Amp. If the output short circuit in this mode, the charger will go into error mode. You should press the power button to turn off the charger, correct the problem, then restart the charger (go to charger or power supply mode).

LONG-TERM CHARGING
After the battery is fully charged, the charger will deliver 13,6V with a maximum of 35A. This is indicated by all battery LEDs slowly pulsating.

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
