Normally, when you change 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. The Car Data Saver solve it all can be used to keep your car's computer powered while you perform battery change. It needs an additional car or a 12V storage battery as a power supplier and outputs the voltage which it receives to the car whose storage battery you want to be change. Two connection options are available to allow the memory protector to be connected either through the cigarette lighter socket or directly to the vehicles battery leads.

It is a very useful tool for workshops, roadside assistance applications and other car service.
