5.2 Mode Selection
Press the MODE button on the charger to cycle through the available charging modes:
- LOW: Lower current charging mode.
- MEDIUM: Medium current charging mode.
- HIGH: High current charging mode (peak 25A).
- REPAIR: Special mode for reconditioning old or low lead-acid batteries.

The selected mode will be displayed on the LCD screen. Choose the appropriate current based on your battery's capacity and charging requirements. The repair mode is specifically for lead-acid batteries that are old or have been unused for a long time.
5.3 9-Stage Smart Charging Process
The charger employs a sophisticated 9-stage charging process to ensure optimal battery health and longevity:
- Battery Desulfation: Breaks down lead sulfate crystals that can form on discharged batteries.
- Soft Start Charging: Gently introduces current to the battery.
- Bulk Charging: Charges the battery at its maximum rate to approximately 80% capacity.
- Absorption Charging: Charges at a decreasing rate to bring the battery to 100% capacity.
- Trickle Charging: Maintains the battery at full charge.
- Battery Test: Checks the battery's ability to hold a charge.
- Recondition: Applies a higher voltage to equalize cells and improve battery performance (for lead-acid).
- Float & Maintenance Charging: Keeps the battery at optimal voltage without overcharging.
- Small Current Maintenance: Provides minimal current to keep the battery topped off during long-term storage.

5.4 LCD Display Information
The LCD screen provides critical information during operation:
- Battery Voltage (V): Current voltage of the connected battery.
- Charging Current (A): Current flowing into the battery.
- Charging Temperature: Ambient temperature detected by the charger.
- Battery Charge Level: Visual indicator of battery capacity (e.g., 20%, 40%, 60%, 80%, 100%).
- Mode Indicator: Shows the currently selected charging mode (LOW, MEDIUM, HIGH, REPAIR).
- Summer Mode / Winter Mode: Automatic adjustment of charging parameters based on ambient temperature.

7. Troubleshooting
If you encounter issues with your Haisito 25A Smart Car Battery Charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not power on. | No power from outlet; faulty power cord; internal fault. | Check power outlet with another device. Inspect power cord for damage. If problem persists, contact support. |
| Charger displays an error or warning. | Reverse polarity connection; short circuit; overvoltage/undervoltage; overheating. | Disconnect from power and battery. Verify correct polarity (+ to +, - to -). Check for short circuits. Allow charger to cool if overheating. Reconnect carefully. |
| Battery is not charging or charging slowly. | Poor connection; incorrect mode selected; battery is severely discharged or damaged; battery type incompatibility. | Ensure alligator clips are securely connected. Select a higher current mode if appropriate. Note that fully discharged batteries cannot be activated. Verify battery type is compatible (Lithium, LiFePO4, Lead-Acid). |
| Repair mode does not activate or work. | Battery is not a lead-acid type; battery is completely dead; severe internal battery damage. | Repair mode is only for lead-acid batteries. It cannot revive a completely dead battery. Consider professional battery testing or replacement. |
