So we setup the charge station - only had one controller so we rotated both packs through it (we have our extra, Wii isn't here yet). I noticed that the red synch button wouldn't activate the remote? Tried the AA's, blue LED's like normal.
The battery packs appeared to be charging (blue to green LED cycle). I figured it would be odd for both to be bad. I was about to get my meter and check it out, when I found a post with a link from a Nyko charger review.
Pretty simple - the positive [+] battery terminal needs a small bend out to make solid contact. Talking a 30 second fix per battery. Odd, as it seems like a design flaw, or maybe there was a slight change to production remotes?
Anyway, full info and more detailed explanation of the fix is here:
