##### battery
This segment will display your current battery status (fails gracefully
on systems without a battery). It can be customized in your .zshrc
with the environment variables detailed below with their default values.
POWERLEVEL9K_BATTERY_CHARGING="yellow"
POWERLEVEL9K_BATTERY_CHARGED="green"
POWERLEVEL9K_BATTERY_DISCONNECTED=$DEFAULT_COLOR
POWERLEVEL9K_BATTERY_LOW_THRESHOLD=10
POWERLEVEL9K_BATTERY_LOW_COLOR="red"
In addition to the above it supports standard _FOREGROUND value without affecting the icon color
Supports both OS X and Linux(time remaining requires the acpi program on Linux)
##### context
The `context` segment (user@host string) is conditional. This lets you enable it, but only display
