The information regarding your battery status and ACPI is stored in /proc and /sys file system. The easiest way to read this information is using the various commands line option tools as well as GUI tool on Linux operating system.
upower command: a command line tool for UPower which provides an interface to enumerate power sources on the system and control system-wide power management.
acpi command: shows battery status and other ACPI information from /proc and /sys file system.
/sys/class/power_supply/BAT0/ directory: store ACPI information about your first battery.
Use upower command to check battery status from command line
Type the following command
upower -i /org/freedesktop/UPower/devices/battery_BAT0

Use apci command to check battery status using terminal
The acpi command may not be installed by default so use apt-get command or yum command to install the same:
yum install acpitool
Ubuntu / Debian
apt-get install acpitool
