I'm thinking of buying a new laptop and wish to do some moderate gaming on it. Some of them have sealed-in batteries (Asus K551, Dell 7535 for example). Isn't this a bad idea? Laptop batteries get affected by heat and these laptops are equipped with some mid-range dedicated graphics cards and processors. They do have ULV processors but wouldn't processor/graphics intensive tasks like regular gaming generate heat and do massive damage to the battery if it is always inside the laptop, rendering it useless within about a year if not a few months? Or is there something I'm missing here?
