Default Graphing a charge/discharge cycle
A little while back I bought a meter from Radio Shack with a rs232 port and some software. Thought I would monitor a battery test and see how it does. How often should I sample the battery?

I have this meter also.
The fastest sample rate my software has is 1 second.
I believe the software tells you how much time it can record at this setting. If its not enough, then choose a higher number like 5 seconds.

Hope this helps

A discharge at 250 to 300ma is will take 2 to 4 hours. How many data points do you need?

I dont really know. I was thinking about every 10 minutes or so. Sound reasonable!

Thirty to forty data points should make a reasonably smooth graph.
