- [Upgraded OBDII Memory Saver Cable] MRCARTOOL B80 Car Memory Saver is specifically designed for automotive battery replacement.When replacing the vehicle battery, connect a spare battery and the vehicle's OBD2 interface to the B80 emergency power cable to prevent loss of vehicle operating data.
- [Voltage and Current Display]Automotive Memory Saver with Real-Time Voltage and Current Display.Voltage Display: Shows battery voltage during replacement (prevents using depleted batteries; ensures uninterrupted power).Current Display: Detects circuit leaks or measures vehicle quiescent current in ignition-off state.
- [Auto Leakage Detection Function] The automotive battery replacement memory saver enables preliminary detection of vehicle leakage by monitoring current values. Simply remove fuses in the car's fuse box one by one and observe current fluctuations. A sudden increase in current indicates potential leakage in the circuit corresponding to that fuse.
- [Safety Protection] Device operating voltage range: 10~14V. Triggers an audible alarm when voltage is <10V or >14V. Automatically activates power-off protection if device voltage exceeds 16V. Features auto-polarity recognition to prevent reverse connection damage; includes built-in 3A fast-blow fuse for overload protection.
- NOTE: The B80 can only be used as an emergency power supply for car battery replacement and cannot be used to power car computers for a long time. Please replace and install a new car battery as soon as possible.
