Actually you'll see those messages on a 'normal' verbose boot, ie 
there's nothing extra logged of note regarding battery issues.  If you 
are up for lots more output on one boot at least, perhaps try what 
acpi(4) suggests:

           debug.acpi.layer="ACPI_ALL_COMPONENTS ACPI_ALL_DRIVERS"
           debug.acpi.level="ACPI_LV_ALL_EXCEPTIONS"

which is less deep, but wider :)  Communications with batteries often, 
likely usually, is moderated by the embedded controler (ACPI_EC) and it 
wouldn't hurt to report any exceptions from other subsystems also. If 
that yields nothing useful you could increase the level ..

Sorry, I can't read messages backwards very well, so I'll drop the tail.

cheers, Ian
