OBD II ECU Memory Saver for Battery Replacement
This OBD II ECU memory saver cable helps preserve vehicle codes, radio presets, ECU settings, and electronic memory when replacing a car battery. It connects a 12V DC power source to the vehicle’s OBD II port, helping prevent data loss and unnecessary system resets during battery changes.

Gold-Plated OBD Pins for Reliable Contact
Unlike many OBD memory saver cables with zinc-plated pins, this cable uses gold-plated OBD contacts for better electrical conductivity, more stable contact, and reliable power transmission during use.

Extra-Long 3m / 10ft Cable
Designed with a 3m / 10ft long cable, this automotive memory saver gives you more flexibility than standard 3–5ft cables. It can be powered by a jump starter, 12V lead-acid battery, or even another vehicle’s 12V cigarette lighter power outlet when a jump starter is not available.

8A Fast-Blow Fuse Protection
Built with an 8A fast-blow fuse, the cable helps protect the wire and vehicle ECU from overload. If the input current exceeds 8A or the voltage exceeds 14V, the fuse blows quickly to cut off the circuit and improve safety during battery replacement.

Works with Multiple 12V DC Power Sources
This automotive computer memory saver is compatible with common 12V DC power sources, including jump starters, 12V lead-acid batteries, and another vehicle’s 12V power outlet. Simply connect the 16-pin OBD plug to the vehicle being serviced and connect the other end to a stable 12V power source before replacing the battery.

6AWG Pure Copper Wire for Safer Power Transmission
Made with 6AWG pure copper wiring, this OBD II emergency power supply cable offers strong current-carrying capacity for stable power delivery. It supports normal operating current of 1–5A and helps withstand short current fluctuations, reducing the risk of overheating and improving reliability.
