I have received a different battery (wrong connector) than what I have ordered. I have notified the seller immediately and their system confirmed receipt of my request for replacement, then nothing happened for over a week until I sent emails to customer services. I keep receiving a general, impersonal return instruction where I have to do all the heavy lifting and MAYBE I might get back some of the postage costs if they are happy with it. No information if the item will be replaced, refunded or nothing will happen. The communications seem to be automated and do not acknowledge this is because they have sent me the wrong item. WOULD NOT RECOMMEND Wonderland Models.
