NAME

6       battery - This module reads battery status
7

DESCRIPTION

9       This module reads battery status from /sys/class/power_supply and uses
10       udev to monitor for changes.
11
12       Note that it is common (and "normal") for batteries to be in the state
13       unknown under certain conditions.
14
15       For example, some have been seen to enter the unknown state when charg‐
16       ing and the capacity reaches ~90%. The battery then stays in unknown,
17       rather than charging, until it has been fully charged and enters the
18       state full.
19
20       This does not happen with all batteries, and other batteries may enter
21       the state unknown under other conditions.
