As soon as I get home from a show, I immediately plug the A10's slide-out USB connector into my computer to download files off of it overnight so they are readily available for editing in the morning. Of course, while the A10 is connected to my computer, it is recharging. So I literally never worry about my A10 being charged up; I don't even include it on my gear checklist.
With my Roland R-07, I checked the batteries every show; and changed them at least every other show. So it was something I really had to stay on top of. But those days are in the past now that I have an A10.
