12V/24V Car Battery Tester

The electrical tester for reducing diagnostic time in all 6- to 30-volt vehicle electrical systems. 


ltem No.


1. Easy to confirm if a circuit is positive, negative, or open without having to reconnect clips from one battery pole to another.
2. Test for continuity with its built-in auxiliary ground lead.
3. By pressing the power switch, the positive or negative current will be conducted to the probe tip for testing the function of an electrical component without the use of jumper wires.
4.Test for poor ground contacts instantly without performing voltage drop tests. it is also short-circuit protected, its internal circuit breaker will trip if it becomes overloaded.
5. Follow and locate short circuits without wasting fuses. It's long cable allows you to test along the entire length of the vehicle without constantly searching for suitable vehicle grounds.


1. Tiny deviation and more precise testing data
2. Can protect the circuit when power supply is reversed
3. Support input voltage range from 9V to 70V
4. Multi-languages available even the minority languages can be customized
5. The Large battery clip can carry more load
6. The 10m diagnostic cable is made of environmentally-friendly material, not pungent
