FAQ

What exactly is the task / function of the component?
The battery stores electrical energy for the starting process and on-board power supply stabilization and records the charge status and current flow in the sensor system. Capacity, cold start performance and charging voltage must match the application.

How can you recognize a defect / typical symptoms?
Defects manifest themselves in weak starting, a sharp drop in voltage under load, charging problems, housing deformation or unusual heating. In the case of sensor systems, error messages or incorrect charging strategies also occur.

How do you check / test the component?
Open-circuit voltage, voltage behavior under load, line and terminal loss and, if necessary, a conductance or capacitance test are tested. Visual inspection for sulphation, loose poles, cracks and electrolyte leakage is mandatory.

When should it be replaced?
The battery should be replaced if it fails the load test, there is a significant loss of capacity or the housing is damaged. Depending on usage and charging care, you can usually expect the reserve to decrease after several years of operation.

How do you check compatibility?
The nominal voltage, Ah/CCA value, housing size, pole arrangement, mounting, battery technology and, if applicable, sensor integration are important. The charger, alternator characteristic curve and existing connection cables must also be compatible.
