That boolean is set when the battery charge drops below the battery.charge.low level.

Generally at work we set that to 50% to maximise the useful life of the batteries (we don't care about runtime past 5 minutes or so) and set battery.charge.restart to 50%.

We use FreeBSD though so the actual details of the shutdown are a bit different I believe.
