Comment (by Quozl):

 These batteries have not been used in other experiments, and have only
 been used in the B-Test-1 units.  They have not been charged except
 through EC firmware control.

 Over charge may have happened on 2006-12-19, read ticket #596 for battery
 history, note the temperature observation "too hot to hold".  This was not
 intentional, but apparently caused by defect.

 Regardless, it may be possible for batteries to be over charged by other
 means external to the unit ... they are removable batteries ... so the
 firmware should take that into consideration.  The firmware should not
 assume it has continuous control over the batteries.
