I just bought a BL-5J battery from Amazon (not from one of their other sellers) that appears authentic. The hologram checks out, with the various dots visible from the correct angle and the physical package of the battery also appears correct.
However, the new battery seems to have strange performance characteristics. Specifically, it will show a 100% full battery meter for 8 - 10 hours, then with just a little bit of use (sending and receiving a couple SMS messages) it will drop to empty.
I'd say it's a fake, my two spares showed similar design values before I even charged them.
Plus the whole full -> empty thing happens with non-Nokia batteries, as with the Mugen
I have 2 spare batteries from Japod and I'm very happy with them. From DealExtreme. The price is very good and the performance is almost on par with the original ones.
I'll buy Japod anytime. No need for (fake or non-fake) originals anymore !
this happened to me too. mine is fake. it only has 650MAh capacity and stays that way then suddenly turns 5/650 after 2 hours. good thing its only a spare.

left you can see the Graph for my "new" (propably Fake) battery.
After my N900 shut down without any alert i put in my original half charged battery (as you can see on the right)
