XO power management

[Ismael Schinca]

We would really like to have a relatively accurate result *as fast as
possible *of the condition of a battery. That's what I'm trying to get to.
I could run the olpc-pwr-log on 15 batteries aprox. Used batteries but in a
"probably good" condition.
I'm also trying to get some really bad but functioning batteries to test
them. Don't have them yet.
I'll try to run the script on those 15 batteries today and share the results
here. I could attach the csv files for example. My idea is to deplete the
batteries and run the script from that point on. Let me know if you would
prefer another procedure.
