Yep, it affects all my batteries, oh joy.

There are many reports of the K-series showing degenerated status as well.
After a few charges they show 1, 2 and sometimes even 3 on the 0-4 scale where other series show 0 which is "new" condition.

In Sweden many users have had their K-series batteries replaced as well by Nikon.

Well, it appears that my batteries are not affected. whew,
