DCB Speedbox battery which uses 8 user supplied AA NiMH batteries (not included)
Comes with carrying case, charger and cable for Nikon
used it for one wedding... works fine with fast recharge times.. the only thing is i am not used to the cable attaching to my waist then to my camera. i put the D3 wth 85 f1.4D & SB800 on the table with cable still attached to my waist (i forgot), then i walked away.... all this during a wedding..
i was super lucky that the metal hood to the lens took the hit and destroyed the hood, but lens and camera was fine.
