wmbattery - 2.51-2 main

wmbattery displays the status of your laptop's battery in a small icon.
This includes if it is plugged in, if the battery is charging, how many
minutes of battery life remain, and battery status (high - green, low -
yellow, or critical - red).
.
There's nothing in the program that makes it require WindowMaker, except
maybe the look. It can be docked in WindowMaker or AfterStep's dock.
.
wmbattery supports multi-battery machines, and can estimate how long
it will take the battery to finish charging or discharging.
