Battery Capacity Tester

This test fixture was a project I completed for Herb Hainey and Associates. The purpose of the project was to be able to perform accurarte and repeatable battery discharge test with varrying loads. In doing so the load de-rating factor could be determined for different types of batteries. The RS-232 port was used both to provide data output from the battery discharge as well as user input for setting up new test sequences. The results were imported directly from HyperTerminal to Excel where I could compile and plot the data, for a sample set of data check HERE
