- [Upgraded OBDII Memory Saver Cable] MRCARTOOL 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] The OBD memory saver can also be used for preliminary detection of electrical leakage in vehicles. Connect it to a charged spare battery and the OBD port to monitor current/voltage. Sequentially pull fuses while watching current. A sudden drop indicates potential drain in that circuit. Cross-reference the wiring diagram to pinpoint affected components.
- [Protection Function] During battery replacement, disable door light triggers, ensure full vehicle power shutdown, and deactivate all electrical appliances to prevent current surges. This OBD2 memory saver operates at 10-14V (triggering audible alarms at <10V or >14V), featuring triple electrical protection (over-current/over-voltage/reverse-polarity) with a reinforced 3A fast-blow fuse. Automatic power-off activates when voltage exceeds 16V.
