4.2 Charging Modes and Current Selection
The charger offers three speed current selections (Low, Medium, High) and a dedicated Repair Mode. The charger automatically recognizes the battery voltage and suggests appropriate current levels.
| Voltage | Low Current | Medium Current | High Current |
|---|---|---|---|
| 6V | 2A | 5A | 10A |
| 12V | 3A | 20A | 45A |
| 24V | 5A | 10A | 18A |

4.3 9-Stage Smart Charging Process
The charger employs a 9-stage smart charging process for efficient and safe battery charging:
- Battery desulfation
- Soft start charging
- Bulk charging
- Absorption charging
- Trickle charging
- Battery test
- Recondition charging
- Float & maintenance charging
- Small current to maintain charging
This fully automatic process detects battery condition, desulfates, and repairs automatically.

5. Maintenance and Repair Mode
5.1 Repair Mode
The Repair Mode (PUL) is designed to improve battery performance, provide stronger engine starts, and extend battery life. It automatically detects sulfation and acid stratification, then repairs and reverses battery damage. This mode is particularly useful for bringing older or deeply discharged batteries back to life.

8. User Tips
- Charging Deeply Discharged Batteries: The charger's intelligent control and repair mode are designed to handle deeply discharged batteries. If your battery is in a sub-charge protection mode, the charger's desulfation and recondition stages may help reactivate it.
- Optimal Charging Speed: For faster charging, select the 'High' current mode appropriate for your battery voltage. For maintenance or smaller batteries, 'Low' or 'Medium' might be more suitable.
- Temperature Adaptation: Allow the charger to operate in its automatic Winter/Summer mode for optimal charging performance based on ambient temperature.
