The Circle Pad Pro may require one triple A battery but according to the latest reports from Japan, the battery will last a long time.
Japanese website Andriasang reports that the manual for the Circle Pad Pro (due for release on 10 December in Japan) states that you can expect 480 hours of play time from one battery.
Considering Resident Evil Revelations is ten hours long (not counting Raid mode), you'll be able to play through it with the Circle Pad Pro without having to worry about the battery life. Although you might need to recharge your 3DS!
It's also good news as you need to use a screwdriver to get the battery compartment open.
The Circle Pad Pro will be released in the UK on 27 January, on the same day as Resident Evil Revelations.
