✨ECU OBD2 memory voltage backup cable, anti‑reset tool ✨

When replacing a car battery, disconnecting power or electrical repairs, ECU, radio, sensors, comfort settings and error codes are often lost. After reconnecting the battery, you need to reprogram many functions, adjust sensors, enter the radio code and delete unnecessary diagnostic errors. This OBD2 voltage support cable solves this problem in a simple way. It allows you to maintain a constant power supply to your car modules when replacing or disconnecting the main battery. The kit offers two ways of power supply: a car cigarette lighter socket and crocodiles for connecting an external backup battery. Thanks to the long cable, you have freedom of movement around the vehicle during service work. The device is designed for workshop mechanics and for private users performing self-repair and replacement of the battery. Protects all saved vehicle settings from memory loss, saves your time and eliminates the need to re-encode modules after each battery replacement.

➡ Complete OBD2 memory backup cable kit ⬇

✔ Main cable with OBD‑II plug and car cigarette lighter plug with signal diode ✔ Separate cable with crocodiles and female cigarette lighter socket ✔ Two independent power supply options to choose from depending on operating conditions ✔ Durable, flexible long-length cable for convenient work on the car

You can power the car's memory either through the cigarette lighter socket of an external source, or with crocodiles connected to an additional battery. The diode on the cigarette lighter plug informs about the correct voltage supply.

⭐Proper step-by-step connection procedure⭐

1 Connect crocodiles to external battery: red to pole plus (+), black to pole minus (−). 2 Insert the OBD‑II plug into the car diagnostic socket. 3 Check if the LED is lit – this means the correct power supply to the vehicle’s memory. 4 You can safely disconnect and replace the main car battery.

⚠ Important note: Do not reverse the poles! Incorrect plus/minus connection can damage the kit components and car electronics. After the battery replacement is complete, first connect the main battery of the vehicle, only then disconnect the support cable.

✅Convenience of work when replacing the battery outside the vehicle✅

With a long cable length, you can place the external spare battery on the floor of your workshop or driveway without having to hold it inside the cabin. The OBD plug remains in the diagnostic socket, the car door can be closed for the time of battery replacement, the cable freely passes through the door gap. You do not have to leave the door open, you do not risk closing the keys inside the vehicle.

✨How to work with a backup battery inside the cabin✨

If you have a smaller auxiliary battery, you can place it directly inside the car on the floor. Connect crocodiles to auxiliary battery, female cigarette lighter socket connect with main wire plug. The whole set is compact, does not take up much space, allows you to freely operate when installing the main battery under the hood. The indicator light constantly shows the power status.
