Set the battery in conky correctly

Configure the battery at Conky can be a nightmare looking for this solution at web 'cus there isn't very information about it. I already had this problem...


ACPI battery number is given as argument, at 'funtions' battery, battery_bar and battery_percent. By default the argument is BAT0. But if it doen't work, let's find out the correct argument:

  • Open the terminal and type:
$ ls /proc/acpi/battery

  • There can be various kind of output:
CMB0
BAT1
BAT0
...etc
My output was: CMB0

  • Open the .conkyrc file and edit to (examples):
${battery CMB0}
${battery_bar CMB0}
${battery_percent CMB0}

Obviously, replace CMB0 with the output you received earlier.
