Schumacher Electric Memory Saver Detector

Save your settings before removing your battery. Schumacher's OBD-L Memory Saver Detector automatically detects if the vehicle's electronics will allow this device to save on-board data. Attach between a portable power unit and a vehicle's On-Board Data (OBDII) diagnostic port, to maintain power to the vehicle's on-board microprocessor-controlled devices when the vehicle's battery is disconnected for service or replacement.
