6. Operating Instructions

Once connected, follow these steps to operate the charger and select the appropriate charging mode.

Automatic Battery Recognition:

The charger automatically identifies 12V or 24V lead-acid batteries. For 12V LiFePO4 batteries, manual selection is required.

Selecting Battery Type:

• Press the Battery Selection button to cycle through available battery types (e.g., STD, AGM, GEL, LiFePO4). Select the type that matches your battery.

Selecting Charging Current:

• Press the Current Selection button to choose the desired charging current. Available options are:
• 12V: 5A, 10A, 25A
• 24V: 5A, 10A, 12A

Starting and Stopping Charge:

• After selecting the battery type and current, press the START/STOP button to begin charging.
• The LCD display will show the charging progress, including current voltage and percentage.
• To stop charging at any time, press the START/STOP button again.

6-Stage Smart Charging Process:

The charger employs an advanced 6-stage charging process for optimal battery health and longevity:

1. Desulfation: High-frequency pulse charge to break down lead sulfate.
2. Soft Start: Gradually introduces current to protect the battery.
3. Bulk Charge: Charges the battery to approximately 80% capacity at maximum current.
4. Absorption Charge: Charges the battery to 100% at a decreasing current.
5. Analysis: Checks battery condition.
6. Float/Trickle Charge: Maintains the battery at full charge with a small, constant current, preventing overcharging.

Repair Mode:

The repair mode is designed to recondition sulfated, undervoltage, or long-term idle batteries.

• To activate, ensure the charger is connected to the battery, then press the Repair Mode button.
• The charger will attempt to restore the battery's capacity. This process can take several hours.
• 0V Start: If the battery voltage is 0V, the repair mode can be used to initiate charging.

Temperature Adaptive Charging:

The charger automatically adjusts the charging voltage based on ambient temperature to prevent overcharging or undercharging.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your battery charger.

• Cleaning: Disconnect the charger from power and battery. Wipe the casing with a soft, dry cloth. Do not use harsh chemicals or abrasives.
