1. Introduction and Product Overview
The Beyprern Automatic Pulse Repair Battery Reconditioner is designed to restore and extend the lifespan of various lead-acid batteries by addressing sulfation, a common cause of battery failure. This device utilizes advanced pulse reconditioner technology to dissolve sulfate crystals on battery plates, thereby improving battery performance and capacity.
It is suitable for 12V to 48V lead-acid batteries, including AGM, GEL, EFB, MF, Flooded, VRLA, and SLA types, commonly found in cars, trucks, motorcycles, SUVs, golf carts, farm vehicles, and motorboats.

2. Safety Information
- Always wear appropriate personal protective equipment, including eye protection and gloves, when working with batteries.
- Ensure adequate ventilation in the work area to prevent the accumulation of explosive gases.
- Avoid sparks, flames, and smoking near batteries, as they can produce flammable hydrogen gas.
- Connect the desulfator to the battery terminals correctly: RED clip to the positive (+) terminal and BLACK clip to the negative (-) terminal. Incorrect connection can damage the device or battery.
- Do not attempt to desulfate a physically damaged battery, a battery with dried electrolyte, or a completely dead battery (below recommended voltage thresholds).
- Keep the device away from water and extreme temperatures.
- This device operates by drawing power from the battery itself; no external power supply is needed.

4. Setup Instructions
- Initial Voltage Check: Before connecting the desulfator, ensure the battery voltage is above the minimum threshold for its voltage class. If the battery voltage is below the specified value, charge the battery using a standard charger until it reaches the minimum operating voltage.
- For 12V batteries: Voltage must be > 11.5V
- For 24V batteries: Voltage must be > 22V
- For 36V batteries: Voltage must be > 33V
- For 48V batteries: Voltage must be > 44V
- Connect Clips: Connect the RED alligator clip to the positive (+) terminal of the battery. Connect the BLACK alligator clip to the negative (-) terminal of the battery. Ensure a secure connection.
- Verify Operation: Once connected, the desulfator will automatically begin operation. The red light on the device will flash, and a sound may be emitted, indicating that the desulfurizer is active.

5. Operating Instructions
- Automatic Operation: The desulfator operates automatically once connected to a battery with sufficient voltage. It will continuously emit high-frequency pulses to break down sulfate crystals.
- Repair Duration: For batteries that have been in use for more than six months and require significant repair, the desulfating process can take 1 to 3 weeks. For optimal results, leave the device connected to the battery for more than 15 days.
- Monitoring: The device's display will show the battery voltage, and the "Pulsing" indicator light will confirm active operation.

6. Maintenance
Regular desulfation can help maintain battery health and prevent future sulfation buildup. For daily or routine maintenance, it is recommended to connect the desulfator to the battery for approximately 6-7 hours.
- Keep the desulfator clean and dry.
- Inspect the alligator clips and cables for any signs of wear or damage before each use.
- Store the device in a cool, dry place when not in use.

7. Troubleshooting
- Device Not Activating:
- Check if the alligator clips are securely connected to the correct battery terminals (red to positive, black to negative).
- Verify that the battery voltage meets the minimum requirements (e.g., >11.5V for a 12V battery). If not, charge the battery first.
- Battery Not Improving:
- The desulfating process requires time. Ensure the device has been connected for the recommended duration (1-3 weeks for significant repair).
- Not all batteries can be fully restored. The desulfator is effective for sulfated batteries but cannot repair batteries with physical damage, dried-up electrolyte, or those that are completely dead.
- Ensure the battery is capable of holding some charge for the desulfator to operate effectively.
- Unusual Sounds or Smells: Disconnect the device immediately and inspect the battery and connections for any issues. Consult a professional if concerns persist.
