Nope.  This is right too.

When a laptop reports values in mA the values are normalised by multiplying by
voltage.  The original values as reported by ACPI are in the "reported."
namespace, whereas the normalised values are in the "charge_level." namespace. 
We have to do this in order to properly calculate overall percentage of battery
power left on multiple battery systems that report battery capacity in mAh and
have batteries with two different voltages.

See http://bugzilla.gnome.org/show_bug.cgi?id=309944 and
http://lists.freedesktop.org/archives/hal/2005-July/002834.html for more
information. (in the end, the unit that we decided to report is microwatthours
since you can reach it most easily, ie: just multiply mV by mAh).
