I am pretty sure that the DSI uses Lithium-Ion Batteries. In order to replace it you would have to special order it, probably from Nintendo.
The 3DS uses a proprietary battery made specially for it by Nintendo. Therefore the only battery it takes is a 'Nintendo 3DS' rechargable battery.
No, there won't be.
The Nintendo 3DS's battery life is described by Nintendo3DS.com below: "When playing Nintendo 3DS software about 3-5 hours. When playing Nintendo DS software about 5-8 hours. Battery duration differs depending on the brightness setting of the screen. The information regarding battery duration is a rough standard. It can be shorter depending on what functions of the Nintendo 3DS system are used."
