The (often referred to in technical communities as the "New YR104" or a variation of the Yaorea/MIB series) is a high-precision battery internal resistance tester designed for professionals and hobbyists who need to monitor battery health with extreme accuracy. This tool uses the 4-wire AC Kelvin method to eliminate the resistance of the test leads themselves, ensuring that the measurement you see is strictly the battery's performance. Core Technical Specifications
: Unlike standard multimeters, the YR104 uses a 1KHz AC signal to measure internal resistance. This is the industry standard for determining the true state of health (SOH) of a cell. mib yr104 new

The MIB YR104 is a universal tool, compatible with almost all common chemistries, including: Lithium-Ion (Li-ion) and Lithium Polymer (LiPo). Lithium Iron Phosphate (LiFePO4). Lead-Acid (Pb). Nickel-Metal Hydride (NiMH) and Nickel-Cadmium (NiCd). Alkaline and Dry cells.
The "New" version of this device typically features improved internal hardware for faster sampling and better stability compared to legacy models like the YR1030. 0.01mΩ to 200Ω.
