Autool BT30 Memory Saver
The Autool BT30 Memory Saver is an OBD emergency power cable that allows you to continue supplying power to the vehicle while replacing a battery, so that important settings (such as ECU parameters and key information) are retained. The BT30 uses a fully integrated voltage and current display system, providing you with real-time insight into the electrical behavior of the vehicle during maintenance.
This tool is essential for professional technicians who want to safely and controlled replace a battery without the risk of data loss. The BT30 is also suitable for simple leakage diagnosis by analyzing the quiescent current via the OBD port. Thanks to the built-in fuse and reverse polarity protection, the device is safe to use, even with inexperienced operation.
