I have my 3ds since September 2011 and I never replaced its battery.
It does seem to last a little less than it used to when I bought it, something like 20-25 minutes less, but I really don´t feel any serious problems with it.
I bought a 3ds USB cable and an external battery pack that I use when on long trips or 3ds fans meetings (where we do use a lot of local play )
