This is a milliohmmeter that can measure extremely small resistances on the order of mΩ. As a battery tester, you can check the deterioration status of lithium-ion batteries, nickel-metal hydride batteries, lead-acid batteries, LiFe batteries, etc.

By measuring circuit patterns and cable resistance, you can determine the losses when high currents flow. Additionally, it can be used for matching the degree of battery degradation.
