With lithium ion batteries, I can get well over 50 hours on a set of batteries. I just checked and right now, I have 3225 minutes on the current set and the only material I've been reading is from Audible.com. I expect to get another one to two hours on this set, maybe less--the power indicator is beginning to drop, although this time, it's dropping much more slowly than usual. I thought I'd have to change batteries yesterday, but it's still telling me 85%. ----- Original Message ----- From: "Philip Hall" <phall1246@xxxxxxxxxxxxx> To: "bookport" <bookport@xxxxxxxxxxxxx> Sent: Sunday, November 26, 2006 3:12 PM Subject: [bookport] battery life A while ago, someone had asked about battery life. I usually get about 1400 minutes when playing audio files. phil
