I don't have the battery/AC icon turned on because, for the most part, there's no reason for it to be there - I typically get cord-free 5 or so hours at a time, so it seems redundant.
Still, occasionally my laptop will just turn off due to the battery having been depleted.
So, I was wondering if it's possible to have some sort of "Warning, battery is at 1%!" notification in, say, notification center or via Growl?
Currently I just type "pmset -g batt" in the terminal, which I generally have open anyway, to get my estimation. But I would like a more automatic method of doing this, if at all possible.
