MR CARTOOL B50 battery tester tool is for testing the performance of start-up lead-acid batteries.
B50 voltage tester uses a large--screen LCD and the test process and results can be displayed through sound alarms and icons.
The internal protection of the device has been strengthened to prevent it from reverse polarity connection, high voltage access, and poor test clamp contact, which ensures more security and convenience in the operation.
Two modes for voltage detection: 12V/24V. After the device is powered on, it will automatically identify the 12V or 24V battery voltage type and display the measured voltage and battery status on the LCD screen.
