Step-by-Step Guide to Unplugging a Car Battery
Step 1: Turn Off the Engine and Remove the Keys
The first thing that you must always remember and adhere to is that the car engine should be off and the keys taken out of the ignition. With the help of this step, the current does not flow through the electrical system during the test.

The one with a higher voltage positive terminal is colored with red paint or situated with a plus (+) sign. In comparison, the one with a lower voltage or negative terminal is covered with black color or situated with a minus (-) sign.
Step 5: Wear Safety Gea
Wear your safety gloves and glasses to prevent you from being adversely affected by some risk factors.
Step 6: Disconnect the Negative Terminal First
With the help of a wrench or even a socket set, remove the nut of the negative terminal (black or featuring the ‘-‘ mark).
