【How to Use】:
Step 1, Insert the jump starter into the 18V/20V battery and the green light will come on. Connect it to the positive and negative terminals of the car battery (12V cars only) .
Step 2, if the green light blinks, please wait. It is charging the car battery until the green light stays on. If your car battery is extremely low, it may take several 18V/20 batteries to charge the car battery to the minimum level that will allow it to start.
Step 3, if the green light stays on, it means the car battery meets the minimum charge for starting. At this point, start the car.
Step 4, when the car starts, please remove the starter from the car battery and let the car engine continue to run. Finally, remove the battery from the starter.
