Or the "Nikon of the Exploding Case," if you prefer. Using OEM parts in expensive equipment is elementary, dear Watson, but MobileMag is reporting that some people are using cheap replacement Lithium batteries in their D70s and getting disasterous results. The cheap batteries don't have integrated voltage regulation and they can overheat and explode. Fortunately no one has had a camera held up to their eye when it exploded yet. Some of the cases may have involved: users may have thought they were getting official replacement parts. As a result, Nikon now puts holographic stickers on their betteries; look for them.

And while the reports on MobileMag are about Nikons, the lesson here should be for everyone to use OEM replacement parts. We saw this same thing a couple of years a o with cell phones, and we've seen it with various laptops; Lithium batteries just aren't something you want to mess around with. Get the OEM part with the appropriate embedded circuits.
