OBD devices use varying amounts of current from the battery even when the vehicle is turned off. Batteries also drain for various reasons with or without an OBD device plugged in. For instance, leaving your car idle for an extended period of time, turning your ignition on but not your engine, or just having an old or weak battery can cause battery drainage. We have designed Vinli to use the smallest amount of current but the health of your battery can speed up the battery drain. If you have a weak or older car battery, we recommend unplugging Vinli after you shut off your engine. If you have experienced a dead battery and you have Vinli plugged in, please contact us so we can take a look into it.
