5.3 Advanced 8-Stage Procés de càrrega

The charger utilizes an advanced 8-stage charging process to ensure optimal battery health and longevity:

1. Battery Desulfation: Removes sulfate crystals from battery plates.
2. Inici suau: Gradually introduces power to prevent damage to deeply discharged batteries.
3. Càrrega massiva: Charges the battery at its maximum rate until it reaches approximately 80% capacity.
4. Absorció: Càrrecs a la baixaasing rate to bring the battery to 100% capacity.
5. Anàlisi de la bateria: Tests the battery condition to determine if it can hold a charge.
6. Reacondicionament de la bateria: Further reconditions the battery to improve performance.
7. Càrrega flotant: Maintains the battery at a full charge without overcharging.
8. Monitorització intel·ligent: Continuously monitors the battery and re-initiates charging if needed.

5.6 Using the Pulse Repair Function

The Pulse Repair function is designed to restore the performance of older or sulfated batteries. It works by automatically detecting sulfation and acid stratification and applying pulse technology to break down these deposits. This can significantly extend the life and improve the starting power of your battery. Note: This function cannot activate or charge totally dead batteries.

6. Manteniment

6.1 Atenció general

• Keep the charger clean and dry. Wipe with a soft, dry cloth.
• Guardeu el carregador en un lloc fresc i sec quan no l'utilitzeu.
• Inspeccioneu els cables i el clamps regularly for damage. Replace if necessary.

6.2 Emmagatzematge a llarg termini

For batteries stored over long periods, utilize the trickle/float charging mode. This will keep the battery optimally charged and prevent degradation, ensuring it remains in good condition for months.

7. Solució De Problemes
