The use of a second battery charger makes sense if an inverter or other 12 V consumers are used more frequently in a vehicle. To avoid excessive discharge of the starter battery, it is recommended to install a second battery as well as a second battery charger.
Please note that inverters or 12 V consumers are only connected to the second battery. If the second battery is exhausted, the engine can still be started via the starter battery.

Thanks to the intelligent charge management of the secondary battery charger, the energy produced at peak times can be easily and effectively stored in a second battery. In this way, the energy supply of particularly important consumers can be ensured at any time in a simple manner.
Examples of use
Important consumers that must always function, such as alarm systems or cooling devices, are connected to the primary battery. The secondary battery supplies power to less important consumers, such as TV or radio sets.
