In my recent reading on Li-Ion batteries, it appears that they last longest if they are charged more frequently and rarely deep-cycled, which is completely the opposite of NiCad and NIMH batteries. If the Toyota Prius is any indication, and characteristics of large-cell NiMH are the same as small-size AAA, you are wrong about NiMH.

... Aha! A mere $59 for Apple to send a replacement unit, great. I wonder if Apple re-downloads all the music. Why would they need to do that? The music data is stored either on HD, or on flash media. Neither needs battery power to retain data. Because Apple doesn't give you the same iPod, they give you a replacement with a new HD. I suspect [Prius does this] to prevent overcharging, or too deep discharge, and to keep temps within a reasonable range. Does anyone have information on how these cars perform in really close climates, such as Alaska, or Newfoundland? Cold climates? Yeah, my mom lives in upstate NY and the Prius does not perform well in winter. Battery power suffers, and it handles poorly on snowy or icy roads.

Well, not a problem here (Texas), and I saw a brand new one yesterday going past me in a Wal-Mart parking lot. Completely silent. Rather nice.
