Battery Internal Resistance Tester, 4-Wire Voltage & Resistance Test for Lead, Li, Ni-Cr Batteries (100V, 200Ω)

Struggling with inaccurate battery diagnostics that cost you time and money? The Battery Internal Resistance Tester from amiciKart delivers laboratory-grade precision in a pocket-sized, portable instrument — so you can measure what truly matters inside your battery.

This professional-grade tester uses the 4-wire (Kelvin) measurement method, which eliminates contact resistance errors and delivers significantly more accurate readings than standard 2-wire testers. It measures internal resistance from 0.001mΩ to 200Ω and voltage from 0.001V to 100V DC, with a class-leading ±0.5% accuracy and a rapid 5 readings per second test speed. Whether you're working with lead-acid, lithium-ion, or Ni-Cr battery packs, this single instrument handles them all — making it the only tester you need on your bench or in the field.

Designed for real-world portability, it runs on a built-in 1000mAh lithium battery that charges from any standard 5V/1A phone charger — no proprietary adapters, no hassle. The auto shut-off after 10 minutes of inactivity ensures your battery life is conserved between tests. Ideal for battery manufacturers, EV technicians, R&D labs, solar energy installers, and electronics maintenance professionals who need reliable, repeatable data on every test cycle.
