I agree. I had accidentally left the PB100 on (sleep mode of course!) for about 2 days and the battery is still about 80% good. I was surprised to find it still functioning. I believe that the sleep mode is slightly more battery draining than an actual shutdown. Also during that 2 day period, I was driving from Baltimore, MD to Boston (about 450 miles). The PB was in my trunk taking all the vibration from my Ford Taurus... I think I am very lucky or the Harddisk must have been parked during the sleep mode
