Operating the Charger
8-Stage Multi-Charging Process
The ECOBOXX Infinity charger utilizes an advanced 8-stage charging process to optimize battery health and longevity. This process includes:
- Battery Test and Precharge: Initial assessment of battery condition.
- Desulfation (STD/AGM): Breaks down lead sulfate crystals that can form on battery plates.
- Soft Start: Gently introduces current to prevent damage to deeply discharged batteries.
- Bulk Charging: Charges the battery to approximately 80% capacity at maximum current.
- Absorption: Charges the battery to 100% capacity at a decreasing current.
- Analysis: Checks if the battery can hold a charge.
- Float: Maintains the battery at full charge with a constant voltage.
- Pulse (STD/AGM): Applies small pulses of current to keep the battery optimized during long-term maintenance.
The charger can revive dead batteries: STD/AGM batteries from 0.8V and Li batteries from 0V.
Bluetooth App Monitoring (InfinityLink)
The Infinity mobile app provides comprehensive real-time data and control over your charging process. Key features include:
- Charging History: View past charging cycles and performance.
- Current Battery Status: Monitor voltage, current, and charging phase.
- Error Warnings: Receive alerts for any issues during charging.
- Device Settings: Adjust charger parameters and update firmware.

Maintenance
To ensure the longevity and optimal performance of your ECOBOXX Infinity Battery Charger, follow these maintenance guidelines:
- Cleaning: Disconnect the charger from both AC power and the battery before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the charger in a cool, dry place when not in use. Ensure cables are neatly coiled and not kinked.
- Cable Inspection: Regularly inspect the AC power cord and battery clamps for any signs of damage, fraying, or corrosion. Replace if necessary.
- IP65 Rating: The charger is rated IP65, providing protection against dust and low-pressure water jets. While it offers protection, avoid submerging the unit or exposing it to high-pressure water.
Troubleshooting
If you encounter issues with your ECOBOXX Infinity Battery Charger, refer to the following common troubleshooting tips:
- Charger Not Turning On:
- Ensure the AC power cord is securely plugged into a live outlet.
- Check if the outlet is functioning by plugging in another device.
- No Charging Indication:
- Verify that the battery clamps are correctly connected to the positive (+) and negative (-) terminals.
- Ensure the battery voltage is within the charger's operating range (e.g., 0.8V for STD/AGM, 0V for Li).
- Check the selected battery type and charging current using the MODE button.
- Error Indicator On:
- An error light typically indicates a problem such as reverse polarity, short-circuit, or over-voltage. Disconnect the charger, rectify the issue (e.g., correct clamp connection), and reconnect.
- If the error persists, the battery might be severely damaged or incompatible.
- Bluetooth Connectivity Issues:
- Ensure Bluetooth is enabled on your smartphone and the InfinityLink app has necessary permissions.
- Make sure you are within range of the charger.
- Try restarting both the charger (by unplugging and replugging) and the app.
- Battery Not Fully Charging:
- The charger is designed for maintenance and charging, not necessarily to "resurrect" severely damaged or dead batteries that cannot hold a charge.
- Ensure the battery capacity is within the charger's supported range (10-250Ah for 8A model).
