- Multi-Protection: Includes over-current, over-charge, over-temperature, short-circuit, over-voltage, and reverse connection protection.
2. Important Safety Information
Always read and understand all safety instructions before using the charger. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Use the charger only for the specified voltage and battery types.
- Ensure proper ventilation during charging to prevent gas buildup.
- Avoid sparks or flames near the battery during charging.
- Connect the charger to the battery terminals correctly (positive to positive, negative to negative).
- Disconnect the AC power before disconnecting the battery clamps.
- Do not immerse the charger in water.
- Keep out of reach of children.
3. What's Included
The BYGD 5A Smart Car Battery Charger S5000 package includes:
- BYGD 5A Smart Car Battery Charger Unit
- Battery Clamps (Red for Positive, Black for Negative)
- AC Power Cord
- User Manual
The charger unit is compact and lightweight, designed for easy portability and storage. The cables provide approximately 150cm (59.06 inches) of reach.
4. Setup and Connection
Follow these steps to safely connect the charger to your battery:
- Ensure the charger is unplugged from the AC power outlet.
- Connect the red positive (+) battery clamp to the positive (+) terminal of the battery.
- Connect the black negative (-) battery clamp to the negative (-) terminal of the battery.
- Plug the charger's AC power cord into a suitable wall outlet.
- The charger will automatically detect the battery voltage and begin the charging process.
5. Operating Modes
The charger features multiple operating modes to suit different battery types and conditions. Use the 'MODE' button to cycle through the available options:
- 12V Mode: 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 Repair Mode: Extends the life of old, idle, or slightly damaged batteries by removing sulfation and repairing them with pulse repair technology.
- 6V Mode: 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 voltage is detected.
6. LED Indicators and Charging Progress
The charger features LED indicators to communicate the charging status and any potential issues:
- Pulsing Red LED: Indicates the battery is less than 75% charged and is actively charging.
- Pulsing Green LED: Indicates the bulk charge is complete, and the battery is being optimized for extended life.
- Solid Green 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.
- Error Indicators: 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-stage charging process:
- Step 1: Pre-charge
- Step 2: Charge Detection and Diagnosis
- Step 3: Constant Current Charging
- Step 4: Constant Voltage Charging
- Step 5: Trickle Maintenance Charging
Estimated Charging Times
The following table provides approximate charging times for different battery capacities (for reference only):
| Battery Type | Battery Capacity | Charging Time (Approx.) |
|---|---|---|
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 2-10Ah | 0.5-3h |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 10-20Ah | 3-6h |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 20-40Ah | 6-12h |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 40-80Ah | 12-18h |
| Lead-Acid, AGM, Wet Cell, Gel Cell, LiPo (with BMS) | 80-120Ah | 18-30h |
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:
- Over-current Protection: Prevents damage from excessive current flow.
- Over-charge Protection: Automatically stops charging when the battery is full to prevent overcharging.
- Over-temperature Protection: Integrated thermal sensor adjusts charging or shuts down if temperatures become unsafe.
- Short-circuit Protection: Protects against damage from short-circuited connections.
- Over-voltage Protection: Safeguards against damage from excessive voltage.
- Reverse Connection Protection: Prevents damage if battery clamps are connected incorrectly.
Temperature Compensation
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.
