5. Modes de funcionament
The charger features multiple operating modes to suit different battery types and conditions. Use the 'MODE' button to cycle through the available options:
- Mode 12 V: For 12V lead-acid batteries (wet, gel, enhanced flooded, maintenance-free, calcium).
- 12V AGM/SLA Mode: Specifically for 12V AGM and SLA batteries.
- Mode de liti de 12 V: For 12V Li-ion batteries with BMS, including LiFePO4.
- 12V Repair Mode: Extends the life of old, idle, or slightly damaged batteries by removing sulfation and repairing them with pulse repair technology.
- Mode 6 V: For 6V lead-acid batteries (wet, gel, enhanced flooded, maintenance-free, calcium).
- 12V Supply Mode: 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 voltages detecta e.
6. LED Indicators and Charging Progress
The charger features LED indicators to communicate the charging status and any potential issues:
- LED vermell intermitent: Indicates the battery is less than 75% charged and is actively charging.
- LED verd intermitent: Indicates the bulk charge is complete, and the battery is being optimized for extended life.
- LED verd continu: 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.
- Indicadors d'error: 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 Charging Process
The charger utilizes an intelligent 5-step, 4-stagprocés de càrrega electrònica:
- Step 1: Pre-charge
- Step 2: Charge Detection and Diagnosis
- Step 3: Constant Current Charging
- Pas 4: Vol constanttage Càrrega
- Step 5: Trickle Maintenance Charging

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:
- Protecció contra sobreintensitat: Evita els danys causats per un flux de corrent excessiu.
- Protecció de sobrecàrrega: Automatically stops charging when the battery is full to prevent overcharging.
- Protecció de sobretemperatura: Integrated thermal sensor adjusts charging or shuts down if temperatures become unsafe.
- Protecció contra curtcircuits: Protects against damage from short-circuited connections.
