The 12V/24V Battery Internal Resistance Tester, a versatile tool designed for measuring various battery types, including lithium, lead-acid, alkaline, and more. This tester is ideal for use in automobiles, motorcycles, and electric vehicles.

• 1KHz AC low resistance measurement technology with noise filter technology . It can be used on thebatteries without disconnected from working condition
  

• Measuring principle 4-terminal Kelvin connection method to avoid interfere of wire resistance and contact resistance
  

• Auto range both in resistance and voltage measurement
  

• Simultaneously measure and display readings of battery resistance and voltage.
  

• Built-in ambient temperature measurement.
  

• Pass / Fail comparison function for resistance and voltage

1. -can be set to activate automatically and manually

2. -auto hold readings and comparison conclusion in one screen
