Response from LEGO SHOP

Nicholas, Technical Product Specialist, LEGO® Consumer ServicesThank you very much for providing us with this feedback. Our technical teams are looking into the reason why this happened to your battery box. We can say that we have discovered that Duracell brand batteries have a slightly shorter than normal positive output which prevent it from coming into contact with the metal contact plates inside the battery box. Try swapping out your Duracell batteries with another brand, that should fix the issue. If you are still having trouble give our customer service representatives a call, they will be happy to help you. Thank you again for your feedback.
