Prepare Your Car Battery for Charging (Step-1)

It’s essential to take some safety measures before attaching the charger to charge your battery. Make sure your car is parked in a garage or in any space which is well ventilated and free of rain.

First, take the red clip I mean the positive one and attach it to the positive terminal of the battery. When you are sure enough that you have connected it securely, then, take the black or negative one.
And attach the negative clip to the marked negative connection that you selected from the previous step.

Remember, never touch the wire when the charger is plugged in and turned on as it may cause severe shock and fatality.
Also, don’t forget to keep the wires apart from each other.

Switch On the Charger and Check the Display (Step-4)
