My D2x, which I bought May 3, 2005 still has the ORIGINAL battery. I only have one, single battery for the camera. It is now ten full years old. Plus three days shy of another five months tacked on to those ten years. Take a look at where this battery is in its life cycle--after basically, ten and a half years. The battery has sat around for about 30 days since being charged, and is at 81% charge.
There is no way in hell that any cheap made in China aftermarket battery can compete with Nikon's original batteries.
