Memory Saver for Car Battery, OBD-II Port Emergency Power Supply Cable for Battery Change Preserve Presets, Battery Cigarette Lighter Power Extension Socket with 2 Alligator Clips

Specification Item Type: Memory Saver Material: ABS + Metal Instructions and Operation: Powered by any jumper starter with a 12 volt socket and connected to the OBD II memory saver. Interface connec vtor between 12V DC power supply and vehicle OBD II port. Keep vehicle codes and electronic presets. Replacing a car battery on an older vehicle used to be simple. You unhooked the old battery and then installed the new one. However, newer cars rely on a computer to operate everything from the stereo to the transmission. If the computer loses power, the settings will be lost and must be reset to the default settings. This means that the vehicle may feel different while driving and you may need to enter a security code to get into the stereo system. Using this simple memory saving device when replacing your car battery will help you avoid these problems. The device can work with any 12V DC power supply, including jumper starters, 12V DC sealed batteries, or 12V DC power sockets in other cars. As our 3 meter cable unit, this is a handy way if you don't have a jumper starter (or Sealed battery) on hand, and the unit also gets 12V power from another good car's lighter. Simply plug the lighter plug into this car, then plug the 16 pin plug into the OBD port of the car where the battery is to be replaced. Now you can replace the battery. As a typical OBD automatic memory protector, there is no protection on incorrect polarity (AIP), so if the wrong polarity power supply is entered, it may damage your car ECU (Electronic Control Unit). For our new upgraded version of OBD automatic memory saver, it adds the safety function of AIP; if the input power polarity is incorrect, the AIP function will automatically take effect (if the input power polarity is incorrect, the power cannot be transferred to your car); likewise, the led indicator on the memory protector will not light up. This way, your car's ECU and other electrical equipment are adequately protected during the wrong power connection. Package List 1 x OBD Memory Saver Cable 1 x Clip Cable

• The CYSFETENA OBD II Vehicle ECU Emergency Power Supply Cable works with any 12V DC power source, including: Jump starters (portable lithium or lead-acid types); 12V lead-acid batteries (charged or partially charged); Another car's cigarette lighter outlet (12V power socket); Battery chargers (12V DC output, though lower amp settings like 2A are recommended)
• 【Main Function】the CYSFETENA OBD II Vehicle ECU Emergency Power Supply Cable preserves radio presets along with other electronic settings. By maintaining power to your vehicle's computer while the battery is disconnected, it prevents all programmed data—including radio stations, clock, security codes, and transmission settings—from resetting to factory defaults.The radio presets remain intact after battery replacement, and you won't need to re-enter security codes to access the stereo.
