Just stripping off the comma there is not acceptable, IMO.

Okay, well for me acpi just says 'No support for device type:
power_supply'. 

Does 'acpi' only output *one* line at all times?

If I take your output above, we could do this:

[snip]
PERCENT=${${"$(acpi 2>/dev/null)"}/(#b)[[:space:]]##Battery <->: [^0-9]##, (<->)%*/${match[1]}}
[snap]

Needs extended_glob set, but that's the case in that position already.
Could you two test the expression above. If it works, I'll commit it
later this evening.

Regards, Frank
