Know your Battery status the command line way

Well no big deal:-). The battery information can be easily got by clicking on the battery icon in your Ubuntu's taskbar. The good thing here is you will know from which file the information of the battery is fetched.
To know the current state of the battery:
pradeep@pradeep-laptop:~$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: charging
present rate: 0 mA
remaining capacity: 3599 mAh
present voltage: 12578 mV

To know all the info regarding your laptop battery:
pradeep@pradeep-laptop:~$ cat /proc/acpi/battery/BAT0/info
present: yes
design capacity: 4400 mAh
last full capacity: 3789 mAh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 185 mAh

capacity granularity 1: 56 mAh
capacity granularity 2: 3604 mAh
