Using a true 4-wire Kelvin measurement at 1kHz AC, the AvieHast Battery Internal Resistance Tester reads voltage and internal resistance at the same time, with a DC voltage range of 0 to ±100V, a resistance range up to 200Ω and a stated accuracy of ±0.5%.\u003c\/p\u003e\n\u003cp\u003eBuilt for the bench and the field, the AvieHast Battery Internal Resistance Tester (model HRM10) adds a pass\/fail sorting mode with your own thresholds, stored test history with data table export, user calibration and a rechargeable 1000mAh lithium battery with USB Type-C charging. At just 225g, it is easy to carry between the workshop, the garage and on-site jobs.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose the AvieHast Battery Internal Resistance Tester?\u003c\/h2\u003e\n\u003ch3\u003eAccurate Battery Health Checks Without Lead Resistance Errors\u003c\/h3\u003e\n\u003cp\u003eVoltage alone rarely tells the full story of a battery. A cell can show a healthy voltage yet have high internal resistance that limits its output under load. The AvieHast Battery Internal Resistance Tester uses separate current and sense leads, so the resistance of the test leads themselves is removed from the reading. The result is a more faithful internal impedance figure, helping you match cells, spot weak ones and make better decisions when building or servicing battery packs.\u003c\/p\u003e\n\n\u003ch2\u003eAvieHast Battery Internal Resistance Tester Key Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTrue 4-wire Kelvin measurement method\u003c\/li\u003e\n\u003cli\u003e1kHz AC internal resistance testing\u003c\/li\u003e\n\u003cli\u003eSimultaneous voltage and internal resistance display\u003c\/li\u003e\n\u003cli\u003eDC voltage range of 0 to ±100V\u003c\/li\u003e\n\u003cli\u003eInternal resistance range up to 200Ω\u003c\/li\u003e\n\u003cli\u003e±0.5% stated accuracy\u003c\/li\u003e\n\u003cli\u003e1V, 10V and 100V voltage scales with automatic or manual selection\u003c\/li\u003e\n\u003cli\u003eVoltage resolution down to 0.1V\u003c\/li\u003e\n\u003cli\u003eCell sorting mode with user-set pass\/fail thresholds\u003c\/li\u003e\n\u003cli\u003eTest history storage with data table export\u003c\/li\u003e\n\u003cli\u003eUser calibration support\u003c\/li\u003e\n\u003cli\u003eRechargeable 1000mAh lithium battery with USB Type-C charging (5V\/1A)\u003c\/li\u003e\n\u003cli\u003eCompact 158 × 80mm body weighing 225g\u003c\/li\u003e\n\u003cli\u003eRugged housing with a storage temperature range of −20°C to +80°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e4-Wire Kelvin Testing with the AvieHast Battery Internal Resistance Tester\u003c\/h2\u003e\n\u003ch3\u003eReadings You Can Trust Down to Low Resistance Values\u003c\/h3\u003e\n\u003cp\u003eThe AvieHast Battery Internal Resistance Tester applies a 1kHz AC signal through one pair of leads and measures the response through a second pair.
