In Hoary (I still have it installed in another partition), the gnome panel
applet never displays percentage greater than 100%, either in AC power or on
battery power. But like under Breezy, /proc/acpi/battery/BAT0/state shows a
sudden jump down from 4500mAh to 3800mAh when I unplug the power cable. But in
both states it is never shown as greater than 100% in the applet.

$ cat /proc/acpi/battery/BAT0/info
present:                 yes
design capacity:         4500 mAh
last full capacity:      3800 mAh
battery technology:      rechargeable
design voltage:          9600 mV
design capacity warning: 450 mAh
design capacity low:     136 mAh
capacity granularity 1:  45 mAh
capacity granularity 2:  45 mAh
model number:            DELL579SN
serial number:           3006
battery type:            NiMH
OEM info:                Sanyo

Under AC power:
$ cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            1 mA
remaining capacity:      4500 mAh
present voltage:         10801 mV

Under battery power a few seconds later:
$ cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            1742 mA
remaining capacity:      3797 mAh
present voltage:         10369 mV
