This has been fixed by the following commit on current master branch,
which makes 'M-x battery' list all batteries no matter what they're
named:

    Have `M-x battery' list all batteries under GNU/Linux

I'm therefore closing this bug report.  If you could please verify that
the fix works for you and report back, that would be even better.
