5. Operating Instructions
5.1 Current Selection
The charger offers multiple current options to suit different battery capacities. Press the 'AMP' button to cycle through the available current settings:
- 12V Mode: 5A, 10A, 15A, 20A
- 24V Mode: 5A, 10A
Select a current appropriate for your battery's capacity to ensure safe and efficient charging. For example, a 100Ah battery might be charged at 10A or 20A depending on desired charging speed and battery specifications.
Figure 5.1: Selectable current levels for 12V and 24V batteries.
5.2 0V Activation for LiFePO4 Batteries
The charger can activate deeply discharged 12V/24V LiFePO4 batteries that have dropped to 0V. This function attempts to restore the battery to a normal voltage level, allowing for a regular charging cycle. Chargers without this feature may fail to recognize and charge such batteries.

5.3 Low-Temperature Charging
For lead-acid batteries, the charger can operate in low-temperature mode, ensuring efficient charging even in cold environments. This is particularly useful for winter maintenance of vehicle batteries.
5.4 Lead-Acid Battery Reconditioning
The 12V lead-acid reconditioning mode uses a 15V pulse charge to revitalize old, unused, damaged, stratified, or sulfated lead-acid batteries. This process can significantly extend battery life and improve performance.
5.5 Charging Efficiency
The charger is designed for efficient power transfer, minimizing charging times. For example, a 12V 100Ah LiFePO4 battery can be fully charged in approximately 5 hours using the 12V 20A setting.

6. Maintenance
To ensure the longevity and optimal performance of your ECO-WORTHY battery charger, follow these maintenance guidelines:
- Cleaning: Regularly wipe the charger's exterior with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the charger in a cool, dry place away from direct sunlight, moisture, and extreme temperatures.
- Cable Inspection: Periodically inspect the AC power cord and battery connection cables for any signs of damage, fraying, or corrosion. Replace if necessary.
- Ventilation: Ensure the cooling fan and ventilation openings are free from dust and debris to prevent overheating.
7. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on | No AC power; Faulty power cord | Check wall outlet and power cord connection. Try a different outlet. |
| Charger not charging battery | Incorrect battery connection; Battery deeply discharged (0V); Incorrect battery mode selected; Battery fault | Ensure correct polarity (+ to +, - to -). For LiFePO4, allow 0V activation. Verify selected battery mode. Test battery with another device. |
| LCD shows error code | Reverse polarity; Short circuit; Overheating | Disconnect immediately. Check connections for correct polarity. Inspect cables for shorts. Allow charger to cool down. |
| Slow charging | Low current setting; Large battery capacity; Battery degradation | Increase current setting if battery allows. Charging large batteries takes longer. Consider battery replacement if degradation is severe. |
If the problem persists after attempting these solutions, please contact ECO-WORTHY customer support.
