A very interesting article over at Coding Horror about rechargeable batteries, and the games the manufacturers play (although they do it in all industries. Megapixels for cameras, GHz for computers, HP for cars…).
A good place to buy is Thomas Distributing. That’s where I ordered my charger, as I live in Canada, and Amazon.ca doesn’t carry electronics. I got mine on sale, so it was less expensive than Amazon anyway.
I’ve ordered the La Crosse Technology BC-900, so expect a followup post once I’m done. One nice thing is it contains adaptors for C and D batteries. You put AA batteries into the adaptors to power items that require the larger batteries. Very nice!
