Apart from the first part of your message, I do not understand what you are saying. Are you saying the battery was faulty, but you did not put that in the listing but told the buyer after the auction ended? So buyer doesn't want to go ahead with the Sale (understandable) So why does he need to pay? I think you can just cancel and put in your reason as "buyer asked to cancel" and then relist it. (make sure you mention the faulty battery) I don"t understand your statement about having no comebacks on yourself as the seller or the buyer. Aren't you the seller?
