Automotive memory saver usually refers to a device or function used to save the settings and memory of automotive electronic equipment during car battery replacement or maintenance. When replacing or disconnecting a car battery, the settings and memory of many electronic systems in the car (such as the navigation system, audio system, seat memory, etc.) may be erased. To avoid this, a car memory saver can be used to retain these settings and memories so that after the battery is reconnected, the vehicle can be restored to its previous state.

The automotive memory saver uses advanced intelligent technology to monitor the status of the vehicle's electronic system in real time by connecting to the vehicle's OBD interface or battery interface. When it is detected that the battery is about to be replaced or has been replaced, the automotive memory saver will start immediately and automatically record the current electronic settings and parameters.
