If you are reclaiming cells from old laptop batteries, use the YR104 to categorize them. Cells with an IR over 100mΩ are generally nearing the end of their high-drain life, while those under 50mΩ are usually in great shape. Final Verdict: Is it Worth It?
Think of internal resistance as the "friction" inside a battery. As a battery ages or gets damaged: The battery gets hotter during use.
Usually supports up to 28V or 45V (depending on the specific sub-model/revision), making it suitable for single cells and small battery packs.
Using the device is straightforward, but accuracy depends on technique:
For the price point, the offers industrial-level precision in a hobbyist-friendly package. While a standard multimeter is fine for checking if a battery is "charged," the YR104 tells you if the battery is healthy .
