By measuring internal resistance and voltage simultaneously, this tester helps you sort, compare, and screen cells with confidence, eliminating the errors caused by test leads and contact resistance.\u003c\/p\u003e \u003cp\u003eDesigned for professional electricians and electronics hobbyists alike, the YR1035 combines a compact, portable build with advanced measurement technology. It offers true 4‑wire AC sinusoidal measurements, a battery sorting function, and a low‑power design with a built‑in 2000mAh battery for longer field use. The display presents resistance and voltage clearly on a single screen, making it easy to assess battery performance at a glance. Whether you’re performing battery matching, performance testing, or routine screening, this tester makes complex measurements simple and reliable.\u003c\/p\u003e \u003cp\u003eWith the ZR function, you can measure ultra‑low resistances down to 0.30–0.50 milliohms for highly accurate assessment of fresh and healthy cells. It supports a wide range of chemistries—including lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry cell, nickel metal hydride, nickel cadmium, and button cells—so you can verify the health of diverse battery types. The device is built for real‑world use: true four‑wire measurements reduce lead effects, and its energy‑efficient design keeps battery life long and reliable in fieldwork.
