I thought it was time to have a look at the workings of a genuine Nikon En-EL14 battery.

There's a lot more going on with the nikon battery to what i first thought, but my first intention was to find how the battery talks to the camera,
I have struggled to find datasheets for the smd's in the above picture any help would be appreciated.
IC1 TF 2N02 1115 is the battery authentication, this ensures the battery only to work with limited amount of camera's by nikon, if nikon have gone this far,
i'm sure nikon would of encrypted the key or it could be in plain text, probably programmable - prob li-ion protection imbedded.
IC2 CD0 192 Li-ion cells charging, protection.
IC3 WV 1D4 ...not certain, could be N/P channel mosfet.

I didn't go to far into this battery, the answer lays in the genuine en-el14.
