Answer:Yes, you can use the Force Start Function to start your car when your car battery is completely dead.We are committed to maximizing your driving convenience, and here to hold your back.
How to use the Force Start Function:
1) Before you start: check your battery level
Make sure that the jump starter battery level is at least 20%.
We recommend you could charge it to 80% or fully charge it.
Note: Even though our product can start dead battery vehicles when the battery level of the jump starter is 20%, we still suggest you recharge the jump starter to above 80% for the best performance. When starting a completely dead battery, the car engine requires more power.
2) 4 steps of the Force Start Function
Step 1: Insert the battery clamps into the jump starter and attach the clamps to the car battery. (The screen may display 'Error code 2' or won't display any instructions.)
Step 2: Press the Power Button and Flashlight Button simultaneously for 2-3 seconds to start the force output.
Step 3: Start the car engine.
Step 4: Remove the clamps from the car battery.
Warning: Please be cautious to use the Force Start Function. When using the Force Start function, auto-detection and safety features will be disabled. Please ensure a correct connection.
