With NIMH batteries, you really do get excellent battery life. This is a great compromise between long life and economics. Also, I do feel like I'm doing something that's environmentally sound, as others have stated. It's perfectly fine to recognize the things we do that are good for the environment, while also recognizing that we engage in some activities that are not great for the environment but which make our lives much better. Since using lots of Alkalines wouldn't make my life better than using NIMH's, I choose the more enviornmentally and economically friendly alternative. <grin> But the point is that if you've only tried the BP (or anything else) with Nicad batteries, consider trying NIMH batteries. They do last much longer, and they work well with the book port. I use the BP for lots of audio, and I get hours and hours on a single charge.

Slightly more frequently, but as I said, I've used them for more than 20 years and have saved hundreds of dollars
