Super Safe to Operate

TOPDON is a brand that is synonymous with safe and advanced technology and this battery tester BT300P is no different. It can automatically monitor the battery activity to make the testing safer and more efficient due to the following built-in protections:

  • Short-Circuit Protection - Protect the operators and the units against short circuit hazards; detect the faults and cut off the circuit immediately before the surge current reaches the maximum.
  • Reverse Connection Protection - Protect your car’s electric system, if the positive battery clamp is accidentally connected to the negative battery terminal and vice versa.
  • Spark Proof - The specially designed clamps are all high-quality ABS plastic covered. So when you’re connecting the connectors to the battery, you won’t worry about the leak of the battery acid which may cause a damaging explosion.
