Check the milli-Ampere-hour capacitance of your rechargeable NiCad batteries

Battery and Charger Diagram | By: Diagram mania

Introduction With this mAh meter you can check the mAh capacitance of your NiCad or NiMH rechargeable batteries Normally the cheaper NiCad AA-type cells have a capacitance of 500-750mAh (NiCAD) the more expensive NiMH AA-cells types are up to 1800mAh. I built this circuit because the capacitance of some of my older NiCad batteries seemed […]
