You know what kind of sucks when using a wireless controller, the battery life. Looks like Wii U owners will face this problem less as Nintendo has release a high-capacity GamePad battery for $32.

According to the product details, it offers 8 hours of use, which is a slight slap in the face to the previous GamePad battery of just 3-5 hours. Installing will involve a screwdriver and I'm sure some directions but this is a small price to pay when your find yourself  constantly recharging the battery.
