Practically indispensable.

This high capacity battery is a good solution. It is double in size from that original. The capacity increases to the original 1500mAh 2550mAh battery thereon. A gain of 1050mAh.

Installation is no problem. The screwdriver is supplied, the battery goes perfectly.

At the autonomy, with the following settings on the Wii U Gamepad: Vibrate mode, OFF economy Backlight 3/5, volume 70%, the battery takes about 6 hours. This is almost double the original battery that she held a little over 3 hours.

In short, from my point of view this accessory is almost indispensable for those who want a finally correct remaining on its Wii U Gamepad. The only drawback to this is that battery which significantly increases the Wii U Gamepad weight to be taken into account. Also note that the time to get a 100% full charge takes longer quavec the original battery.

On the other hand, I can only blame Nintendo for not providing this type of high capacity battery directly with the console.
