4-Wire Kelvin Test Leads for LCR Meters, ESR Testing, Battery Internal Resistance & Capacitance

The ZOYI 4-Wire Kelvin Test Leads are precision accessories designed for use with compatible LCR meters, ESR testers and battery internal resistance meters. Using the four-wire Kelvin sensing method, these leads help eliminate the resistance of the test leads themselves from the measurement, allowing more accurate results when testing very low resistance values.

They are ideal for measuring battery internal resistance, ESR, capacitance, inductance and resistance, making them a useful tool for electronics repair, component testing, battery diagnostics, laboratory use and hobby projects.

The banana plug connection provides easy compatibility with many LCR and resistance testing instruments, while the Kelvin clip design gives a secure and stable connection to the component or battery under test. This helps improve repeatability and reduces measurement errors caused by poor contact.

Whether you are checking capacitor health, testing lithium battery cells, diagnosing circuit components or carrying out low-resistance measurement work, these Kelvin test leads provide the accuracy and stability required for dependable results.
