Module: Battery

The battery module displays the current capacity and state (eg. charging) of your battery.

Config

Addressed by battery

option	typeof	default	description
bat	string		The battery to monitor, as in /sys/class/power_supply/ instead of auto detect.
adapter	string		The adapter to monitor, as in /sys/class/power_supply/ instead of auto detect.
design-capacity	bool	false	Option to enable the use of the design capacity instead of the actual maximal capacity. Thus, even full, the battery may be at less than 100%.
full-at	integer		Define the max percentage of the battery, useful for an old battery, e.g. 96
interval	integer	60	The polling interval (in seconds) for the battery status.
states	array/object		A number of battery states which get activated on certain capacity levels. See States
format	string	{capacity}%	The format, how the information should be displayed.
format-time	string	{H} h {M} min	The format of the estimate of time until full or empty. Use {m} for zero-padded minutes.
format-icons	array/object		Based on the current capacity, the corresponding icon gets selected. The order is low to high. Or by the state if it is an object.
max-length	integer		The maximum length (in characters) the module should display.
rotate	integer		Positive value to rotate the text label.
on-click	string		Command to execute when clicking the module.
on-click-middle	string		Command to execute when you middle click on the module using the mousewheel.
on-click-right	string		Command to execute when you right click on the module.
on-scroll-up	string		Command to execute when scrolling up on the module.
on-scroll-down	string		Command to execute when scrolling down on the module.
smooth-scrolling-threshold	double		Threshold to be used when scrolling.
tooltip	bool	true	Option to enable tooltip on hover.
tooltip-format	string	{timeTo}	The tooltip format.
weighted-average	bool	false	For devices with multiple batteries, an option to display the percentage as an average weighted by the size of the batteries, rather than a simple average of their percentage levels
bat-compatibility	bool	false	Option to enable battery compatibility if not detected.

Format replacements:

string	replacement
{capacity}	Capacity in percentage
{power}	Power draw in watts
{icon}	Icon, as defined in format-icons.
{time}	Estimate of time until full or empty. Note that this is based on the power draw at the last refresh time, not an average.
{cycles}	The amount of charge cycles the highest-capacity battery has seen (Linux only)

Custom Formats:

The battery module allows to define custom formats based on up to two factors. The best fitting format will be selected.

format	description
format-<state>	With states, a custom format can be set depending on the capacity of your battery.
format-<status>	With the status, a custom format can be set depending on the status in /sys/class/power_supply/<bat>/status (in lowercase).
format-<status>-<state>	You can also set a custom format depending on both values.

Custom Tooltip Formats:

The tooltip format can be changed similarly to the label format. The best fitting from tooltip-format, tooltip-format-<state>, tooltip-format-<status> and tooltip-format-<status>-<state> will be used (using the same logic as format-*). Valid tooltip format replacements are as follows:

string	replacement
{capacity}	Capacity in percentage
{power}	Power draw in watts
{time}	Estimate of time until full or empty. Note that this is based on the power draw at the last refresh time, not an average.
{timeTo}	Either an estimate of time until full or empty, or "Full", "Plugged" or "Empty" depending on the current battery status
{cycles}	The amount of charge cycles the highest-capacity battery has seen (Linux only)
{health}	A percentage representing the highest-capacity battery's current maximum charge relative to it's design capacity (Linux only)

States:

• Every entry (state) consists of a <name> (typeof: string) and a <value> (typeof: integer).
  • The state can be addressed as a CSS class in the style.css. The name of the CSS class is the <name> of the state. Each class gets activated when the current capacity is equal or below the configured <value>.
  • Also each state can have its own format. Those can be configured via format-<name>. Or if you want to differentiate a bit more even as format-<status>-<state>. For more information see custom formats.

Example:

"battery": {
    "bat": "BAT2",
    "interval": 60,
    "states": {
        "warning": 30,
        "critical": 15
    },
    "format": "{capacity}% {icon}",
    "format-icons": ["", "", "", "", ""],
    "max-length": 25
}

Style

• #battery
• #battery.<status>
  • <status> is the value of /sys/class/power_supply/<bat>/status in lowercase.
• #battery.<state>
  • <state> can be defined in the config. For more information see states
• #battery.<status>.<state>
  • Combination of both <status> and <state>.

The following classes can apply styles to the entire Waybar:

• window#waybar.battery-<state>
  • <state> can be defined in the config, as previously mentioned.
