Answer: 
I have an EH-5b ac adapter sitting right in front of me, it's the part that actually supplies power to the EP-5B. According the pinout information on the ac adapter, two of the pins aren't connected and the other two pins supply nine volts at up to 4500 mA.

Based on that, it looks to me like you could hook any 9 V power supply, whether a battery or whatever to the EP-5B. It'd probably take a little bit of soldering to do it nicely, but I don't see any huge issues.

Answer: 
I understand your question. Nikon doesn't make what you want. A suggestion is to take the EP-5B adapter and the EH-5 to an electronics repair shop. He can use the male connector on the a/ c adapter to make a plug for the battery you want to use. His is assuming he battery you want to use. (you didn't mention that) is the correct voltage. If not I don't know if there is such a thing as a dc to dc voltage converter. I think the right technician can help you.

Answer: 
EP-5B replaces the EN-EL15 battery in the camera, the EH-5a a/c adapter is attached to it to run on a/c power. If your camera does not use a EN-EL15 battery you cannot use this.

Answer: 
According to Nikon's website the EP-5B is compatible with AC adapter EH-5. Here is a direct quote: "The EP-5B is required when using the AC adapter EH-5/EH-5a to power the camera."

According to the Nikon web site info that I have read ... the Nikon EH-6 AC Adapter (now archived) can be used in combination with the EP-5b Power Supply Connector for the D800.... Correct ?

I also noted that the newer Nikon EH-6b AC Adapter is not listed as compatible with EP-5b....
