Yep, something is amiss. I have a D700 that has sat unused for weeks at times, with no noticeable drain. Even left on in the bag for days, not more than a couple % loss of charge, if that.

My D70 has been in the truck since last fall. I charged it the other day just to be on the safe side. Lithium batteries are the cat's pajamas when it comes to long life.

I've had my D700 with it's battery charged sit dormant for a month and it's still near 100% so I've been very impressed with the LiIon battery's capability of holding on to a charge.

NiMH followed by NiCd have a high rate of "self-discharge" -- sitting idle, they bleed energy through internal resistance. LiON has MUCH lower self-discharge but not as much current handling capability (which isn't a huge issue for dSLRs!)

Cold performance is the other area where batteries suffer "voltage depression". I'm curious what the D700's battery is like under extreme cold, but I suspect it will still be great.

And now for a rather different situation:

Battery 1, original, went completely dead after the first charge.
Battery 2, not original, went completely dead after the first charge.
Battery 3, not original, went completely dead after the first charge.

Battery 1, after the first REcharge only lost 1% in the last 24 hours.

Mocca, do you read me ? ? ?

I will report on what further happens but if things continue for the better it will take some time...

would you mind telling me how did u solve the problem?

I have the same problem, my battery drain out without any use at all within 3 days, and the camera was stored in a bag without any lens mounted.

My battery is also the original one.

Thanks

After the first recharge the original battery stopped giving me problems.
Now not even the non original ones are a problem, I went back to Canon. I think the D700 is a great machine but personally I just couldn't stand the AWB.
Anyhow, I kept the 14-24f2.8, waiting for the 16:9 EF adaptor...

thanks for your reply, I'll try a few more times before visiting NSC

Looks like you got a dud camera.

I had something like that on a D200, but worse and not repeatable in the beginning, and that was something with internal powersupply stabilizer in the camera.
