The problem is, that the new batteries will not charge. The reader says something about it overheating. That is because the new batteries have the wrong thermistor, whatever that is... Based on the info I found in the internet, they use a standard thermistor and Sony used a special one. So the new battery delivers a wrong temperature to the reader, which stops the charging.
edit: this problem occurs with 650 and 350. I did not try to change the battery in the 505 a second time (because tricky...)

Just to make sure...
On the 650: it works fine with an old battery. The new battery throws a temperature error. You put the old battery back in and it works fine?
