Expect the Circle Pad Pro Battery to Last for 480 Hours

Or thereabouts

The Circle Pad Pro attachment needs its own AAA battery, but don't think you'll need to shell out on new ones every time you fancy a game of Resident Evil Revelations.

According to one eager Japanese early adopter, the device's instructions claim it can last for up to 480 hours on a single AAA battery. Good job too, as the battery itself is kept in a compartment held shut by a screw.

The 3DS Circle Pad Pro reaches Europe on 27th January 2012.
