They should definitely be charged by now! Not sure how to explain this, but was there anything inside the light to keep it "off" until you bought it? I have a solar turtle that had a piece of thin plastic in between the metal connections to keep them from touching. I guess it prolongs the rechargeable battery life to keep the connections apart until you set it up. Usually things like that are marked with a big "Remove" arrow, but this one wasn't. Still doesn't work well because I'm in the woods in Wisconsin - glows for maybe 2 minutes at dusk on a really nice day. It's turned into kind of a game - can we actually catch the turtle lit up! One more suggestion for your lights - I think most solar lights have a photo sensor to allow them to come on at dusk - is it dark enough at night to allow them to shine? I mean no other outside lights around anywhere that could be interfering with the photo sensor. We had Christmas lights on a photo sensitive timer one year (on at dusk, off in 8 hours) til we realized that every time a truck drove down the street the headlights would hit the photo sensor and start the whole 8 hours over! Good luck!
