How can I prevent the battery from damage when the unit is disconnected for some time? I came back to a unit that had previously had a successful firmware update and the battery seemed totally dead.* Another unit (yes, I own two) is going to be left alone for a month or so and I can't trust the people involved to plug it into the wall.
*I wound up bringing it back to life by repeatedly issuing the firmware update again and typing pt-battery in Terminal after I got a message that the firmware was successful until the percentage increased past zero. The latter may have been voodoo, but at first, after a few successful pt-battery commands, I'd get an error. This made me think that maybe the battery was falling back asleep or into it the fugue state it had been in. My thought was that by repeatedly issuing the command, I'd keep it awake.
