Battery Discharge Analyzer

The characteristics of the battery, especially the capacity and variation of the voltage on discharge, are needed to be known for circuit design of the battery powered equipments. The technical data of the junk battery is not that always available so that it must be measured by user. But it is hard to record the data by human because the measurement of discharge characteristics takes some hours a cycle. Any data logging system is required to measure the battery characteristics. This project builds a simple automatic battery discharge analyzer.
