There's plenty to laugh about when it comes to the 3DS Slide Pad Expansion peripheral. Battery life isn't among them.

Someone who got the peripheral in advance of its December 10 release date, and was so anxious for dual analogue controls that he tore the box open, says that the manual promises 480 hours of play time off one AAA battery.

Good thing too! See the screw in the above pic? The battery goes into the compartment that's sealed shut by that screw. With 480 hours between changes, you probably won't need to pack a screwdriver with you.

The pic also show that the device comes with a strap.

I hope they will be going to make them colour coordinate....

Dang. If only the 3ds would last that long...
In fact, it would be cooler if the 3ds slide pad extended 3ds battery by 2-3 hours instead...

They could have put another battery into the add-on itself, doubling the life of the console...I don't know why they didn't, the space for such a battery was there after all.

Because it would increase the cost several times ?

Would it really increase the cost that much? They wouldn't have to include an actual battery, just the required circuitry to make it supply power to the 3DS, though that may be easier said than done...

Does anyone know how the circle pad communicates with the main console? Is there some kind of data port or is it done wirelessly?

Sure, but it's sold at 1500 yen, an addon with a battery sold at 2500 yen could even sell better.

Battery would probably cost more than the whole thing currently costs to produce. It would also add more weight as looking at offers in net even chinese knock of batteries for PSP cost few euro and better quality ones around 10.

And also how would they sell people redesign with bigger battery and second analog built in? ;)

why bother replying if you didn't actually read my post?

I said they could sell the battery separately only for those who wanted it... the main concern was if it is at all technically possible to have the add-on supply power to the main unit in the first place? The fact that capcom had to use their own battery for the add-on would suggest the two aren't connected.

Of course it would be possible to design it so it connects to main battery in the same way as current battery extender packs for 3ds are done.
