No, it was a typo in the patch.  Could you replace the line

       (if (battery-search-for-one-match-in-files
            "/sys/class/power_supply/AC/online" "1" 0)
           "AC"

on line 471 of the battery.el, with

       (if (battery-search-for-one-match-in-files
            (list "/sys/class/power_supply/AC/online") "1" 0)
           "AC"

and try again?
