Hi Terri, I know that when I first bought my BN in 2000, battery life was quoted at about 21 hours, but this was before KEYWEB and the ability to stay connected to the Internet. I know that whenever I use the modem, I can almost watch the battery level drop. I would think that activities like word processing and calculating do not drain the battery much, but I would think that Web surfing, heavy Email use, and playing sound recordings would increase drain tremendously, along with heavy accessing of peripherals such as CF cards and microdrives. Also, using speech, or speech and Braille for access drains more current than using Braille alone.
