I don't think it's a bug. Device name is shown you use -D
(to list registered drivers).

The sensor description is "acpibat0 design cap" and you need to
pass the exact string to -s. As there is not naming convention
for sensor descriptions, the device writer uses what he thinks
is better.

In acpibat(4) and acpitz(4) is ok to use device name before the
real string in sensor description, otherwise you wouldn't know
what sensor is from foo0 or foo1.
