BATTERY CHARACTERIZER using PIC18F252

Introduction This circuit is a battery characterizer that applies a fixed load to a charged NiCad or NiMH cell and measures milliamp-hour capacity as it discharges. There is no single load that can be applied to a battery to measure milliamp-hours. It depends on the battery type, it’s intended application, etc. This device is simply
