Under those circumstances, it's hard to say what is bad. I would think that the MOST likely problem is that the battery is shot, followed by a problem with the charger. I think it is unlikely that the problem is with the remote, but stranger things have happened.

I'd contact the seller and explain the problem. Since the battery comes with the charger, I'd ask to have him exchange those first, assuming the remote works fine with regular batteries.
