Increasing timeout didn't help at all :(
Is there a chance that in the future release 8.2 this problem will be fixed? I don't have any idea left how to force acpi to show proper battery state, and I need this information to work with my laptop,  so I think that the best option is to remove or leave unused freebsd for some time :/ and use only linux.

cheers, Kuba
