Not one person at this site has reported an exploding battery, and I'm sure lots of people have bought non-Nokia batteries here.
Here's the difference between a Nokia and non-Nokia battery, as far as I know. The Nokia ones are probably manufactured in China, and sent to Nokia, which packages them with their products. The non-Nokia ones are probably manufactured in China, and are not packaged by Nokia. I wouldn't be a bit surprised to find that some non-Nokia batteries were produced in the same factory as the Nokia ones. Read up on Chinese manufacturing, it's quite interesting.
The ones I have bought were a zillion times cheaper than Nokia, and for me they have worked great.
I don't know about the tablet batteries but for the phones I used a lot of BL-5C batteries that were very cheap ( 1 or 2 euros, because no one bid on them on ebay ) and fake.
They work ok. they don't explode or overheat or anything, but after a month or two they don't hold charge as well as they should. (about the same as my 14 month old, heavily used nokia battery that I wanted to replace) .
My experience is that the official Nokia batteries last very much longer .
I used two different no-name brands from different sellers, I had the same kind of experience with both.

Right, that's a common experience. Not to say it's 100%, because geneven is correct in what he says, too. Buyers just need to realize they're gambling, and decide for themselves if it's worth it or not.
