Within zsh, you need something like (assuming the output is in $string):
setopt extendedglob
local match mbegin mend
if [[ $string = (#b)"Battery "*" charging, "(<->)"%"* ]]; then
print "Charge is ${match[1]}%"
fi
It's up to you how closely you want to match the output, I've matched a
lot of it with *'s.
This works from zsh 4.0.
