ULTIMATE SPEED USBD1 A1 Battery Diagnostic Device, 6 V, 12 V and 24 V

Technical overview
The ULTIMATE SPEED USBD1 A1 Battery Diagnostic Device, 6 V, 12 V and 24 V is designed to test lead-acid batteries in motorcycles, cars and lorries. It can also check the vehicle’s starting and charging systems using its integrated display and dedicated test modes.

Key features
▸ Checks battery health and charge level
▸ Three main test modes for battery, starting and charging systems
▸ Displays loaded voltage, no-load voltage and ripple voltage
▸ Generates QR codes for viewing results on a smartphone
▸ Graphical waveform display function
▸ History function for reviewing saved test results
