It often happens that an old battery is no longer able to start the car engine after being idle overnight in severe frost. Quick release battery terminals are one of the solutions to this problem. Why unscrew the terminals every time to bring the car battery home, if you can buy quick release terminals and do the same operation much faster. The terminals are color-coded - red for plus, blue or black for minus. The principle of installation and removal of the battery is elementary: lift up the cover - the terminal is unclamped, press the cover - the terminal is clamped.
