D2h: battery calibration?

I just bought a used D2h. The camera came with no manual so I can't

read about the battery calibration. I've read mention of it and see

it on the charger. I have 2 batteries.

 

What is it, how and why do I do it?

 

Thanks

The battery charge indicator on the camera can be incorrect if the charging process is interrupted and restarted, or after many charges. The calibration button simply discharges the battery before applying a full charge.

Register the camera with Nikon USA or whatever country you are

in. Then download a manual.<br>

Now as to the battery calibration. The battery charger will tell

you when a battery needs calibration. The information is stored

in the battery itself. Its a long process as the charger

fully discharges the battery and recharges it. New information is

stored in the battery and this process should not need to be done

again for some time.<br>

You can also buy a paper copy of the D2H manual and Nikon may

sell or give you road map style manuals for the EN-EL4

battery pack and MN-21 Quick Charger. Nikon USA charges about $10.00

plus shipping and handling for camera manuals. It should come to

something close to $15.00.<br>

Do not recalibrate a battery unless the charger tell you it needs

it. It's lengthy so do it over night.
