Intelligent Battery Sensor And Battery: Battery

The capacity of the built-in battery depends on the engine used and the vehicle equipment. Selection criteria for the required capacity are:

• the cold-start behavior of the engine
• the standby current consumption of the vehicle
• the energy requirement of the auxiliary consumer units (auxiliary heater, telephone, etc.)

Usually one AGM battery is installed (identifiable on the black housing for batteries installed ex works). In other cases (vehicles without intelligent alternator control and automatic engine start-stop function in some countries), a normal lead-acid battery is fitted.

The AGM battery primarily offers the advantage of greater rechargeability.
