I just bought this and couldn't find out how to hook the batteries up to recharge them. It says in the directions to pull back rubber piece and insert the charger into the batteries but there was no place to insert it. Also I have found that it is for the headlamp and Apollo latern but can't seem to get anyone to confim it. Gave it a 1 star cause I couldnt figure out how to hook it up and the direction sucked. I am sure it would be great if I could figure out how to hook it up.
