The batteries don't always charge fully.  Almost every time I charge a new set, I have to move them around in the charger because one or more didn't charge all the way or never started charging at all.  It's also a very slow charger; it takes several hours to recharge a depleted set of batteries.<br />Updated 5/21: The manufacturer replaced the original charger when they saw my review, which I greatly appreciate.  It still charges slower than I expected, but I haven't had a problem with this new one not charging all of the batteries all the way.
