5. Istruzioni per l'uso
The YONHAN charger offers various modes and current settings for optimal battery care.
Selezione delle modalità di ricarica:
- Press the "MODE" button to cycle through the available charging currents: 1A, 5A, and 10A.
- The charger will automatically detect 12V or 24V batteries.
- Choose the current based on your battery's capacity:
- 1A: For 12V/24V 6-30AH batteries (e.g., motorcycles, small vehicles).
- 5A: For 12V/24V 20-100AH batteries (e.g., cars, SUVs).
- 10A: For 12V/24V 40-200AH batteries (e.g., trucks, boats, RVs).
- The LCD display will show the selected charging mode and the charging progress.

Modalità speciali:
- Modalità di riparazione (PUL): Activates pulse repair technology to help recover sulfated or idle batteries. This mode is indicated by "PUL" on the display. Note: This function cannot revive completely dead or severely damaged batteries.
- 12V DC Mode: Use this mode for charging batteries with a voltage lower than 5V, or to convert the charger into a DC power supply for powering 12V DC devices (e.g., DC fan, oil changer) or as a memory retainer when replacing a battery.
- Winter/Summer Modes: The charger automatically detects ambient temperature and adjusts the charging rate to prevent overcharging in hot weather and undercharging in cold weather. This ensures optimal battery health year-round.

Once the battery is fully charged, the charger will automatically switch to trickle maintenance mode to prevent overcharging and maintain optimal battery health.
6. Manutenzione
Regular maintenance ensures the longevity of your battery and charger.
- Carica di mantenimento: For vehicles or equipment stored for extended periods (e.g., over winter or during holidays), connect the charger in trickle mode to maintain battery charge and prevent self-discharge.
- Riparazione del polso: Periodically use the Repair Mode to rejuvenate sulfated or idle batteries, extending their lifespan.
- Pulizia: Keep the charger and its cables clean and dry. Wipe with a soft, damp stoffa. Non utilizzare prodotti chimici aggressivi.
- Magazzinaggio: Conservare il caricabatterie in un luogo fresco e asciutto quando non in uso.
