Hey Dave. Did you make this using data from the testing of Andree's PP502x work ... or just from your own benches?

My own benches after Andree's work had been committed to svn. They were correct as of the time of the original patch but I don't know if svn has got better (or worse) since then. But when http://www.rockbox.org/tracker/8603 get committed the calibration will need to change again.

I use the iPod 5g 60GB (The battery is the original battery(600mAh)).

My iPod's battery bench result is following:

max battery voltage is maybe 4100 - 4180 mV,
min battery voltage is maybe 3300 - 3360 mV.

These result is different Dave's result.
Is the battery of my iPod old?
