Given that Nokia are pretty big in the mobile phone world, I'm surprised that they have a problem with some of the BL-5C batteries that are made for them by Matsushita in Japan between December 2005 and November 2006.
Check here to see if you are is affected:

My own BL-5C battery was made in Hungary and is not affected by this recall of approx 46 million batteries......
