- PAS 1: DESULFATITZACIÓ - Removes sulphate from the lead plates to restore battery capacity.
- PAS 2: INICI SUAU - Tests if the battery can accept charge. Prevents charging a defective battery.
- PAS 3: A GRANEL - Charges with maximum current until approximately 80% capacity.
- PAS 4: ABSORCIÓ - Charges with decreasing current to 100% capacity.
- PAS 5: ANALITZAR - Tests if the battery can hold charge. If not, the battery may be faulty.
- STEP 6: RECOND (Optional) - Reconditioning mode for deeply discharged batteries.
- STEP 7: FLOAT - Maintains the battery at maximum voltage by providing a constant voltage càrrec.
- STEP 8: PULSE - Maintains the battery at 95-100% capacity. The charger monitors the battery voltage and gives a pulse when needed.
