EEVblog #515 - Battery Ionic Resistance Investigation

Dave investigates the ionic electro-chemical resistance of some Alkaline batteries under light multimeter input loading and an unusual physical battery phenomena, and explains how it differs drastically from the datasheet internal resistance value. He also finds a surprising result showing two types of Alkaline battery construction with different properties. It demonstrates the usefulness of a high resolution bench multimeter.
