INTRODUCTION

Normally, when you replace a car's storage battery, the car's on-board computer will be turned off and the relevant data and personal settings (such as radio station setting, clock setting,etc) will be lost.
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.

To power the car's on-board computer during storage battery replacement, connect the Car Data Saver to either the OBD-II port or the cigarette lighter socket.

Whether the Car Data Saver is connected to the OBD-II port or connected to the cigarette lighter socket, the connection between the Car Data Saver and the port is good if a LED on the Saver lights green.
