Below copy the output of the values obtained by this file:
-----------------------------------------------------
$ cat /sys/class/power_supply/BAT0/uevent
POWER_SUPPLY_NAME=BAT0
POWER_SUPPLY_STATUS=Unknown
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=0
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=10800000
POWER_SUPPLY_VOLTAGE_NOW=10938000
POWER_SUPPLY_POWER_NOW=0
POWER_SUPPLY_ENERGY_FULL_DESIGN=60000000
POWER_SUPPLY_ENERGY_FULL=48920000
POWER_SUPPLY_ENERGY_NOW=18790000
POWER_SUPPLY_CAPACITY=38
POWER_SUPPLY_CAPACITY_LEVEL=Critical
POWER_SUPPLY_MODEL_NAME=45N1107
POWER_SUPPLY_MANUFACTURER=L
POWER_SUPPLY_SERIAL_NUMBER= 4375
-----------------------------------------------------
I had also consulted this file, although it seems that it shows the same
information but with a different format:
-----------------------------------------------------

Thanks for your reply.
