Xit 4 AA Batteries + Turbo Charger

When I first plugged it in, all the lights were green, so I assumed the batteries shipped fully charged. I put two in my camera, and the batteries were almost dead. So, I put them back in the charger and let them charge overnight. Again, dead. Only then did I notice that the charger ships with a protective plastic strips which stops the batteries from connecting (to protect the batteries during shipping, obviously). Once I removed that plastic film, the lights were red (as I had originally expected). They turned green when fully charged, and the batteries have been working great in the camera ever since.EDIT: I may be missing something, but it seems that the charger won't charge if only 2 batteries are in. The lights are green, even if the batteries are both dead. Slipping in a third battery (the fourth doesn't appear to be necessary) turns the lights red and then the batteries charge fine. I still rate this 5 stars, now that I know that. The batteries seem to last forever in a Canon point and shoot.
