- Automatic Recognition: The charger will automatically detect the battery voltage (6V, 12V, or 24V).
6. Operating Instructions
The charger offers different modes for various charging needs. Use the 'MODE' button to cycle through them.
6.1 Charging Modes
Press the 'MODE' button to select the desired charging current. The charger will automatically adjust based on the detected battery voltage.
| Output Voltage | LOW Mode (Current) | MEDIUM Mode (Current) | HIGH Mode (Current) |
|---|---|---|---|
| 6V | 1.5A | 3A | 5A |
| 12V | 2A | 8A | 16A |
| 24V | 2A | 5A | 10A |
6.2 Repair Mode
To activate the pulse repair function, press the 'MODE' button until 'REPAIR' is displayed on the screen. This mode is designed to restore sulfated or stratified batteries. The process may take several hours depending on the battery condition. The display will show 'PUL' during the repair process.
