Important: Always set the correct battery type on the charger before connecting the battery.
The charger supports LiFePO4 (LFP), AGM, and Standard (STD) lead-acid batteries.
AGM Recovery Mode
The charger includes a lead-acid battery repair function, utilizing a 15V pulse to help recover and maintain lead-acid batteries.
The AGM Recovery Mode uses a 15V pulse to repair lead-acid batteries.
Maintenance
To ensure optimal performance and longevity of your charger:
- Keep the charger clean and free from dust and debris.
- Store in a dry, well-ventilated area when not in use.
- Regularly check cables and connectors for any signs of damage.
- The built-in cooling fan helps dissipate heat during operation. Ensure the fan vents are not obstructed.
The internal cooling fan ensures stable and efficient charging performance by dissipating heat.
Troubleshooting
The ECO-WORTHY charger incorporates multiple protection functions to ensure safe operation. If you encounter an issue, refer to the LCD display for fault indicators and consider the following:
- No Display/No Power: Ensure the AC power cord is securely plugged into a live outlet.
- Charging Not Starting:
- Verify battery connections are correct (red to positive, black to negative).
- Check if the correct battery type is selected on the charger.
- For LiFePO4 batteries, if the battery is deeply discharged (0V) and has triggered BMS protection, the charger's activation function should attempt to revive it. If activation fails, the battery may be permanently damaged or require specialized recovery.
- Error Codes/Fault Indicators on LCD: The LCD displays icons for reverse polarity, short circuit, and high temperature. Address the indicated issue:
- Reverse Connection: Disconnect immediately and re-connect with correct polarity.
- Short Circuit: Disconnect the charger and inspect cables and battery terminals for any short circuits.
- High Temperature: Ensure the charger is in a well-ventilated area and not covered. Allow it to cool down before resuming operation.
- Slow Charging: Ensure the selected charging current matches the battery's capacity for optimal speed.
The charger includes multiple protection functions for safe operation.
