Description
The battery command controls or queries the battery. If the battery command is invoked without -d option, the following battery information is displayed:
battery type: NiCd or NiMH
current battery usage: charging, discharging, in use, fully charged
battery capacity
current remaining capacity
full charge count
If the battery command is invoked with -d option, the following battery information is also displayed:

If you use 50% of a battery's capacity and charge it every time (about 20 to 30 times), then the battery cannot be used at more than 50% of its capacity. This is called the memory effect of battery. If, then, the battery is discharged (made empty) and then recharged, the battery can be used at 100% again.
