what to do when gnome power manager shows wrong battery capacity?

Well, if my physics teacher was right then no application shows wrong
values. 6000mAh and 148000mV compute to 88.8Wh.
So either the battery gives wrong values via acpi or the kernel reads
them wrong (which is very unlikely because 6000mAh seem to be a too
normal value for a read error)
