You can use this Car Data Saver to keep your car's computer powered through the OBD-II port or the cigarette lighter socket on the car while you replace the car's storage battery.
The Car Data Saver needs an additional 12V storage battery as a temporary power source. It is a very useful tool for car service.
This Car Data Saver can only be used on 12V car electrical system
