Adam purchased a battery from eBay where the product image contains the eye catching text 40000mAh. But the product description in much Plainer typeset mentions that it is a 10ah battery.
Adam receives the battery the next week and finds that it is 10ah when he had wanted to buy a 10ah battery. Was Adam misled by the trader by their misrepresenting the product?
Does contra proferentum apply or some other principle?
