I believe the Slide Pad communicates with the 3DS thru the infrared port, thus the need of an AAA battery.
Hopefully 480 hours will be enough to keep the thing working until the redesigned 3DS is released (with the 2nd slide pad built-in). This way a battery replacement wouldn't be necessary (unless you want to keep the thing in your collection, on which case I would recommed you remove the battery before storing it).
