Product Information

About this item

• Preserves Vehicle Memory: This OBD II ECU Emergency 12V Power Supply Cable Memory Saver maintains your car’s radio stations, clock time, and engine control unit (ECU) settings during battery replacement by delivering continuous, stable 12V power through the OBD II port—from sources like a jump starter or another vehicle’s cigarette lighter.
• Universal 12V Compatibility: Works with any standard 12V DC power source—including portable jump starters, 12V lead-acid batteries, or a donor vehicle’s cigarette lighter—ensuring dependable memory retention during routine or emergency battery maintenance.
• Safe for All Vehicles: Engineered for drivers, technicians, and roadside assistance professionals, this Memory Saver prevents ECU resets and false warning lights in modern cars, trucks, and SUVs by maintaining stable power to sensitive electronics during battery swaps.
• Durable ABS Construction: Made with high-grade ABS plastic housing and reinforced internal wiring, the Emergency Power Supply Cable includes a fixed protective sheath, safety insulation, and a built-in 8A fuse for consistent overload protection—even under demanding automotive conditions.
• Easy Plug-and-Play Setup: Includes two adapter options—one with a cigarette lighter plug and one with alligator clips—for flexible power sourcing. Simply connect the OBD II end to your vehicle’s diagnostic port and attach the chosen power source—no tools or technical expertise needed.

Warning: 1. Before working with the vehicle battery, always consult the battery manufacturer’s and vehicle manufacturer’s safety instructions, warnings, and guidelines for battery disconnection, removal, and replacement. 2. While connected, the vehicle’s electrical system is powered via the OBD II port through this device—meaning battery terminals remain electrically live. Cover exposed battery connectors with insulating material to prevent short circuits caused by contact with metal or each other. After each use, disconnect the memory saver and clean connectors and cable with a dry cloth. 3. During battery replacement, DO NOT turn the ignition ON (including "ACC ON") while the original battery is disconnected and before the new battery is fully installed—doing so may blow the memory saver’s 8A fuse due to high current surge and overload. 4. Securely insert the OBD II connector of the memory saver into your vehicle’s OBD II port to ensure solid contact; poor connection may interrupt power to the ECU (Electronic Control Unit), potentially causing loss of settings or error codes.
