I was reading about some IC’s from Maxim/ Dallas saying ” Simple battery characterizer” for plotting a charging/ discharging cycles & graphs are available on computer for study I want to plot an extensive data of these batteries.

From MO


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.

PIC-based circuit example from Westford MicroSystems – Battery Characterizer that determines milliamp

Simple Characterization Circuit for Rechargeable AA Cells – Maxim.

Abstract: This characterization circuit, plus a PC and some software, accurately measures the full discharge cycle for a rechargeable AA cell. Cell capacity and output resistance can easily be determined from the curve resulting from these measurements.
