I sold a camera, listing as damage to battery terminals, may or may not work once cleaned. Buyer put in batteries and it did not work, who would expect it to without the clean ? Negative feedback left for me a week ago. Now the buyer has started a return for the item not working.... .... .... But in the description this was stated.. "There is some fairly light corrosion to the battery terminals (photo) - it may just need the terminals cleaning and the camera will work or there may be other issues".
