At work I leave my PCC in my locker with a manual battery in it and I keep my automatic in my pocket. The automatic usually lasts me most of a shift so I might have the manual in my pocket for an hour or two.
At home I just leave them anywhere...usually on top of a pile of CD's or the box I recieved my kit in while they await a trip to the charger.
Those are pretty damn cool looking Infamy. All that matters is that they work.
