if acpi isn't installed the battery charge can be found using
grep -P -o '(?<=^POWER_SUPPLY_CAPACITY=)\w*$' /sys/class/power_supply/BAT0/uevent

BAT=$(acpi -b | grep -E -o '[0-9][0-9]?[0-9]?%')
Oh, true. I guess the following is even more appropriate.
BAT=$(acpi -b | grep -E -o '[0-9]{1,3}%')
However, I do not recall il the braces should be escaped.
