6. Operating Instructions

6.1. Charging Modes

The charger offers four distinct charging modes, selectable via the "Mode" button:

• Standard Mode: For normal capacity 12V lead-acid batteries. This is the default program upon connection.
• Low Capacity Mode: Designed for smaller batteries.
• AGM Mode: Specifically optimized for AGM (Absorbent Glass Mat) batteries.
• Recond Mode (Reconditioning): For deeply discharged or sulfated batteries. This mode increases charging voltage to help re-mix acid and water, revitalizing affected batteries.

6.2. 8-Step Automatic Charging Process

The charger employs an intelligent 8-step process to optimize battery charging and maintenance:

1. Desulphation: Recovers sulfated batteries.
2. Soft Start: Gentle initial charge to protect the battery.
3. Bulk Charge: Charges the battery to approximately 80% capacity.
4. Absorption: Charges the battery to 100% capacity at a decreasing current.
5. Analysis: Tests the battery to determine if it can hold a charge.
6. Recond: (If selected) Reconditions deeply discharged batteries.
7. Float: Maintains the battery at maximum voltage.
8. Pulse: Provides a maintenance charge to keep the battery optimized over long periods.

6.3. Maintenance Charge

The charger can maintain optimal battery voltage and capacity for extended periods, ideal for vehicles stored during winter. Once fully charged, the charger automatically switches to maintenance mode, preventing overcharging and ensuring the battery remains ready for use.

7. Technical Specifications

8. Troubleshooting

If the charger does not operate as expected, refer to the following common issues:

• Charger not turning on:
