First, you should tell us your kernel version and loaded battery module
(battery.ko or sbs.ko)
Second, please do a "grep . /proc/acpi/battery/*/*" with attached AC
and try to do this with it disconnected.
It might be a good idea to open a new bug report in bugzilla.kernel.org 
for ACPI/battery and assign it to
astarikovskiy@suse.de (me).
