5. Driftstilstande
The charger features multiple operating modes to suit different battery types and conditions. Use the 'MODE' button to cycle through the available options:
- 12V tilstand: For 12V lead-acid batteries (wet, gel, enhanced flooded, maintenance-free, calcium).
- 12V AGM/SLA Mode: Specifically for 12V AGM and SLA batteries.
- 12V Lithium Mode: For 12V Li-ion batteries with BMS, including LiFePO4.
- 12V reparationstilstand: Extends the life of old, idle, or slightly damaged batteries by removing sulfation and repairing them with pulse repair technology.
- 6V tilstand: For 6V lead-acid batteries (wet, gel, enhanced flooded, maintenance-free, calcium).
- 12V forsyningstilstand: Converts to DC power to supply any 12VDC device with a maximum supply current of 2A. Use in excess of 2A is strictly prohibited.

Force Mode for Dead Batteries
If your battery is deeply discharged (down to zero volts) and the charger does not detect it automatically, you can activate Force Mode. To do this, press and hold the 'MODE' button for 7 seconds. This will initiate a forced charge for a short period, after which the charger should revert to normal operation if enough voltage er opdaget.
6. LED Indicators and Charging Progress
The charger features LED indicators to communicate the charging status and any potential issues:
- Pulserende rød LED: Indicates the battery is less than 75% charged and is actively charging.
- Pulserende grøn LED: Indicates the bulk charge is complete, and the battery is being optimized for extended life.
- Fast grøn LED: The battery is 100% charged and the charger is in maintenance mode, providing ongoing optimization.
- Pulsing 100% Charge LED (Maintenance): After the battery is fully charged, the charger will continue to monitor and provide maintenance. The 100% charge LED will pulse slowly during this cycle.
- Fejlindikatorer: The charger also has indicators for error conditions such as a bad battery, reversed positive/negative connections, or voltage over 15V. Refer to the included user manual for specific error code explanations.
5-Step, 4-Stage Smart opladningsproces
The charger utilizes an intelligent 5-step, 4-stage opladningsproces:
- Step 1: Pre-charge
- Step 2: Charge Detection and Diagnosis
- Step 3: Constant Current Charging
- Trin 4: Konstant Voltage Opladning
- Step 5: Trickle Maintenance Charging

Forventede opladningstider
The following table provides approximate charging times for different battery capacities (for reference only):
| Batteritype | Batterikapacitet | Opladningstid (ca.) |
|---|---|---|
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 2-10 Ah | 0.5-3 timer |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 10-20 Ah | 3-6 timer |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 20-40 Ah | 6-12 timer |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 40-80 Ah | 12-18 timer |

7. Multi-Protection Features
The BYGD S5000 charger is equipped with comprehensive protection features to ensure safe operation and protect both the charger and the battery:
- Overstrømsbeskyttelse: Forhindrer skader fra for høj strøm.
- Overopladningsbeskyttelse: Automatically stops charging when the battery is full to prevent overcharging.
- Overtemperaturbeskyttelse: Integrated thermal sensor adjusts charging or shuts down if temperatures become unsafe.
- Kortslutningsbeskyttelse: Protects against damage from short-circuited connections.
- Over-voltage Beskyttelse: Beskyttelse mod skader fra overdreven volumentage.
- Omvendt forbindelsesbeskyttelse: Prevents damage if battery clamps er forbundet forkert.

Temperaturkompensation
The integrated digital thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates (e.g., 45°C / 113°F) and under-charging in cold climates (e.g., -20°C / -4°F). This ensures stable performance, low heat generation, and high efficiency across different environmental conditions.

9. Fejlfinding
If the charger is not operating as expected, consider the following:
- Ingen strøm/Ingen indikation: Sørg for, at netledningen er korrekt tilsluttet en stikkontakt. Kontroller, om der er udløste afbrydere.
- Fejl-LED (rød): If a red error LED illuminates, check the battery connections for correct polarity (positive to positive, negative to negative). Ensure the battery is not severely damaged or has a voltage over 15V.
- Deeply Discharged Battery: If the charger does not detect a very low voltage battery, try activating the 'Force Mode' as described in Section 5.
- Langsom opladning: Verify the selected charging mode matches your battery type. Ensure the battery capacity is within the charger's recommended range.
