    "EXhausted Battery" indication

    Kit D7200/18-140 worked perfectly. Then I stored my D7200 for a few months while I was away. Removed lens and battery and stored all in original packing.
    Reassembled everything a couple of days ago, re-charged the battery, put in new 64Gb Sandisk cards and formatted them. Normal operation, took one picture and deleted it.
    Next time I wanted to switch it on an hour or so later, it showed the "exhausted" battery symbol and would not switch on. Thinking the battery was dead after long storage I ordered two new batteries, charged them and put them in the camera. Neither of them would work and the camera still would not switch on and showing the "exhausted" battery icon. That's three batteries, two new and still not switching on. Am I missing something ?

    Try gently wiping the battery contacts inside the camera with a cotton swab and some alcohol. A dry swab would probably be ok if you don't have alcohol on hand.
    Does the charger appear to behave properly? Flashing light that changes to steady after 90 minutes or less? Is there a camera store or a friend where you could try another known good battery?
    For lack of another battery... Try warming up a battery in your hands or hold it out in the warm sun for a few minutes. Don't leave it unattended, you just want to raise the temp 10 degrees or so. Try it in the camera while it still feels warm. If the camera powers up, that might indicate your charger is not charging. Raising the battery temperature can give you a few more milivolts, letting the camera power on for a few seconds. All this will really tell you is that your camera is probably good and all 3 batteries are not charging for some reason.
    I'm already leaning towards your camera is good. If it failed in storage, I don't think you would have gotten the brief power up that you did. As unlikely as it seems, I'm betting on batteries not charging. But don't spend more money based on my guess.
    I must have a really good camera.

    Welcome aboard. Enjoy the ride.
    We look forward to seeing more posts and samples of your work.

    I agree with Nickt's suggestions. I would add to also try cleaning the charger contacts. Also, I would suggest trying your batteries in another camera.

    Re: "EXhausted Battery" indication

    Thank you Nickt. I have cleaned all the contacts as you suggest, I also used a tiny artiists brush to make sure there is no lint or dust between the terminals. I have done this for all three batteries, the original and the two new ones.
    The charger appeared to work properly, initial charging with flashing light for a couple of hours until the light is steady. Subsequent attempts to charge take only about 10 minutes each. Next step will be to visit a camera store to see if they have compatible models to try.
    I'm not sure about the warming up, the ambient temperature here is in the very high 30's celcius so I'm not going to get much more heat into the batteries.
    Interesting to note that when I insert a battery, the green "busy" light flashes for a couple of seconds as I would expect it to and also the LCD display back light will illuminate if requested, so I feel that there is charge in the batteries. But it still will not switch on and shows the dead battery symbol.
    Thanks for the suggestions, maybe I need to find the Nikon service centre tomorrow.

    Thanks Bikerbrent. Tried the cleaning, see my answer to Nickt. Next is to find a camera store to test batteries and camera independently.

    I was hoping it was the batteries or charger, but the charger sounds like it is behaving. If you haven't already tried, remove the lens and memory card. I've seen memory cards hang up the camera, but I have not seen them cause the low battery alert so I don't have high hopes. Good luck.
    I must have a really good camera.

    One final scary though. I am assuming that Bangkok is a pretty humid area. If so, it is possible their is corrosion in the camera from the long term storage. I'll cross my fingers that this is not the case.

    Re: "EXhausted Battery" indication

    This morning I went out to the local camera shop, tried a new battery there with exactly the same result. Four batteries now, same result, kind of rules out a battery problem.
    Just tried naked body, no lens, no cards: no change. Good try though.
    I guess tomorrow I have to find the Nikon repair centre. I'll post the result. Hoping it's something simple though as I am off on a major expedition in a couple of weeks, should have checked the camera before now.
    Thanks for trying.

    Yes, it's very humid here as well as hot. But the camera is only three years old and is used mostly indoors and when I was away for a few months I packed it away carefully in all the original packing so I hope it's not corrosion.
    The mystery is that when I first reassembled it a few days ago it worked perfectly for one test shot, switched it off and a little later, this !

    It still can be battery contact oxidation in the Camera. Cleaning contacts is the wrong term for what needs to be done periodically. Metal exposed to atmospheric oxygen oxidizes to a few molecules thick normally and the resulting oxide of the metal is an insulator. Switch contacts, connectors and bare wires all oxidize and that actually protects the contact from further deeper oxidation but still allows current to flow if the oxide layer is not very deep. But when a contact is exposed for a while and in humid conditions that oxide layer of insulation can grow to be thick enough to not allow the current to jump through the insulating oxide layer. That could be your problem. The solution, in that case, is using a small about of de-oxiding chemical that strips the extra oxygen from the upper layers and returns the metal to conductivity. One popular chemical for that is DeOxit from Craig Laboratories and another is Cramolin ContactClean but another version is D-5 from the same company but in other regions of the world.

    Another possible cause is the memory that uses a small amount of current to maintain the settings when off, a battery in older units or a capacitor in newer one, make be depleted. If that is the case put a battery in it and do a 2 button reset which will return the camera to the factory default settings. Some data is written to eeProm memory and is not impacted, such as shutter count.

    To restoring Nikon D7200 to its default settings, just hold down the [ISO button] button and the [+/- Exposure Compensation button] together, until the control panel turns off briefly while the camera resets itself to the factory default settings. For a dead camera, hold those two buttons while the camera is off and then turn it on while holding the buttons down for 5-10 seconds.
