Nintendo's Wii U Pro Controller (the one that looks like an Xbox 360 pad) has a battery life that lasts up to 80 hours.
That's according to the official product description on Amazon and Gamestop (as noted by Nintendo Life).
In comparison, the Xbox 360 "Play & Charge" kit offers 25-30 hours of charge. The touch-screen Wii U GamePad offers just five hours.
But the Pro Controller does not work with Wii games played on Wii U, the listing added. For these titles you'll need to keep your old Wii Classic Controller Pro handy.
"Your games, your way," the official blurb states. "However you think of your gaming style - hardcore, old school, or purely nostalgic - the Wii U Pro Controller puts you in the game. Designed for accessibility and extended gameplay comfort, the Wii U Pro Controller features the dual analogue sticks and ergonomic button layout that you've come to expect, as well as a rechargeable battery that can last up to 80 hours on a single charge.
"The Wii U Pro Controller can be used for playing a variety of games - from packaged games at retail to downloadable games from the Nintendo eShop. Look on the back of Wii U game packaging to see which games use the Wii U Pro Controller. Not compatible with the Wii system or games."
Nintendo will include a Wii U Pro Controller within the Wii U ZombiU Premium pack when the console launches on 30th November. It will also be available separately. Amazon.co.uk has the pad priced at Ł37.99.
