Battery Comparison Presentation and Data Files

At the regular grotto meeting of 16 February 2021 I gave a presentation comparing the capacity of various kinds of batteries. This post has links to the presentation file and to the data files that I collected.

The data files are plain text, comma-separated values. They can be imported to any spreadsheet or graphing program. I used to create the graphs in the slide show.

The first column in the data files is elapsed time in seconds. The remaining columns should be clearly labeled.

The file names mention which battery was used and what the load resistance was. I collected data on several different Garberiel, Ultrafire and “Purple” batteries. The file names have an appended letter that distinguishes one battery from another.

If you have questions about any of this, let me know.
