to the Wii Remote. Monster Hunter Tri also uses this function by allowing players to save their profiles to the Wii Remote. Pokémon Rumble uses this section to store Pokémon. Carnival Games: Mini Golf and Club Penguin: Game Day! use this to store the player's in game avatars. Power source The Wii Remote uses two AA size alkaline batteries as a power source, which can power a Wii Remote for 60 hours using only the accelerometer functionality and 25 hours using both accelerometer and pointer functionality. In May 2013, Nintendo announced a rechargeable battery and dock accessory, and various third-party manufacturers market charging solutions for the controller (see Wii Remote Chargers). Nintendo's industrial designer Lance Barr said that the Wii Remote's expansion port is unsuitable for internal battery charging. The only type of (externally charged) rechargeable battery supported is nickel-metal hydride (NiMH). A 3300µF capacitor provides a temporary source of power during quick movements of the Wii Remote when connection to the batteries may be temporarily interrupted. If the Wii Remote is not used for more than 5 minutes, such as when the player is using a GameCube controller, it will shut off, and can be re-activated by pressing any button (this was also the case when using a now discontinued video-on-demand service). Games are able to determine and react to the current battery life of Wii Remotes, with certain games using unique, extra-diegetic methods of alerting the player to low battery life. Wii Remote Plus In September 2010, rumors were circulating of a Wii Remote with Wii MotionPlus already built in after the box art for the upcoming FlingSmash revealed it to be bundled with "Wii Remote Plus". Nintendo initially declined to comment, but later announced the device on September 29, 2010, confirming it to be a Wii Remote with MotionPlus built in, allowing players to use peripherals like the Wii Zapper and Wii Wheel and comfortably use the Wii Remote horizontally without having to remove the Wii MotionPlus attachment from the Wii Remote. Wii Remote Plus competed with Microsoft Corporation's Kinect and Sony Computer Entertainment's PlayStation Move with PlayStation Eye motion controllers, respectively. Nintendo later announced that the remote would be available in white, black, blue and pink. It was released in Australia on October 28, 2010, in Europe on November 5, 2010, in North America on November 7, 2010, and in Japan on November 11, 2010. Other
