Choose normal charging first
Identify the battery voltage and chemistry, then choose the supported normal charging mode. GENIUS10 provides several modes, including AGM, lithium and advanced repair functions; their presence does not mean they are interchangeable. Other GENIUS models have different features.

Repair mode has limits
Consult the exact manual for battery eligibility, isolation from the vehicle and voltage precautions. Do not apply a lead-acid repair routine to a lithium battery. Do not use an advanced mode to force a leaking, swollen, frozen or otherwise damaged battery back into service.

A charge is not a diagnosis
If the battery repeatedly fails to start the car after charging, arrange a battery and charging-system assessment. Record the charger indications and battery label. Repeating an advanced cycle without identifying the fault can waste time and expose vehicle electronics to inappropriate conditions.
