An Essential Battery Tester for the Professional Technician

Automotive OEM dealers and service organizations around the world choose The JDiag BT-100 Battery Tester for its proven Battery technology and test algorithms.



JDIAG BT-100 is the best electrical tester for reducing diagnostic time in all 6- to 30-volt vehicle electrical systems, it can test car battery voltage, AC and DC voltage, resistance, leakage, short circuit, components activation etc.


On top of the great features of the BT-100, key features of the BT-100 include:

  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. Support 12V cars and 24V trucks
  7. Overload self protection: reset automatically after overload, no need operation
  8. Available with personalized customization and OEM orders.



JDIAG Battery Tester is the real deal. Compare with dozens of mileage correction tools on the market, it has some clear pros…

  • 10m diagnostic cable
  • Low power consumption and high performance
  • Easy to confirm if a circuit is positive, negative, or open without having to reconnect clips from one battery pole to another.
  • Test for continuity with its built-in auxiliary ground lead.
  • 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.
  • Test for poor ground contacts instantly without performing voltage drop tests. JDIAG BT-100 is also short-circuit protected, its internal circuit breaker will trip if it becomes overloaded.
  • Follow and locate short circuits without wasting fuses. JDIAG BT-100’s long cable allows you to test along the entire length of the vehicle without constantly searching for suitable vehicle grounds.
