7. 3-Step Charging Process
The integrated smart charge controller utilizes a 3-step charging process to optimize battery health and prevent overcharging:
- Càrrega massiva: Delivers a constant current to bring the battery to approximately 80% of its capacity.
- Mode d'absorció: Gradually reduces the charging current while maintaining a constant voltage to bring the battery to full charge.
- Mode flotant: Once the battery is fully charged, the controller switches to a lower, constant voltage to maintain the battery's charge without overcharging or discharging, ensuring it's always ready for use.

8. Característiques de seguretat
Your Battery Tender solar panel is equipped with several safety features to protect both the device and your battery:
- Classificació de resistència a la intempèrie IP67: Provides complete protection against dust ingress and can withstand immersion in water up to 1 meter for 30 minutes, making it suitable for outdoor use in various weather conditions.
- Spark-Proof Design: Connections are designed to prevent sparks during hook-up, enhancing safety.
- Protecció contra càrrega inversa: Prevents current from flowing back from the battery to the solar panel during periods of low light or darkness, safeguarding the battery from discharge.
- Protecció de polaritat inversa: Ensures no charge is sent unless connections are attached correctly, preventing damage from incorrect wiring.
9. Manteniment
To ensure optimal performance and extend the lifespan of your solar panel and battery, follow these simple maintenance guidelines:
- Mantenir net: Regularly wipe the solar panel surface with a soft, damp cloth to remove dust, dirt, and debris that may obstruct sunlight and reduce efficiency.
- Comproveu les connexions: Periodically inspect all cable connections to ensure they are secure and free from corrosion.
- Posicionament òptim: Adjust the panel's angle seasonally to maximize exposure to direct sunlight.
- Eviteu les obstruccions: Ensure no objects (leaves, snow, etc.) are covering the solar panel, as this will reduce its charging capability.
10. Solució De Problemes
If your solar panel is not performing as expected, consider the following:
- No LED Light: Check if the solar panel is receiving sufficient sunlight. Ensure all connections are secure and correctly polarized.
- Battery Not Charging (Flashing Amber): Verify that the battery terminals are clean and that the connections are firm. Ensure the solar panel is in direct sunlight and not obstructed.
- Càrrega lenta: Ensure the solar panel is positioned for maximum sun exposure. Clean the panel surface if it's dirty. Check the battery's overall health; older or damaged batteries may not hold a charge efficiently.
- Sobreescalfament: While the unit is designed to be robust, ensure adequate airflow around the charge controller and battery, especially in hot environments.
