Arduino Battery Capacity Tester V2.0
Green Energy Nov 10,2019
Nowadays fake Lithium and NiMH batteries are everywhere which is sold by advertising with higher capacities than their true capacity. So it is really difficult to distinguish between a real and a fake battery. Similarly, it is difficult to know the capacity retained in the salvaged 18650 laptop batteries. So, a device is required to measure the true capacity of the batteries.In the year 2016, I have written an tutorial on " Arduino Capacity Tester - V1.0 " which was a very straight for...
