In case of laptops one may want battery related information on command-line. To get battery information from command line use:
cat /proc/acpi/battery/BAT0/{info,state}
If only percentage of battery life is desired then following command can be used:
echo $((100*$(sed -n "s/remaining capacity: *\(.*\) m[AW]h/\1/p" /proc/acpi/battery/BAT0/state)/$(sed -n "s/last full capacity: *\(.*\) m[AW]h/\1/p" /proc/acpi/battery/BAT0/info)))%
