<p>thanks Igor:<br>
My posted question was somewhat vague:<br>
I have a Canon 1Ds III battery that, according to the "menu>battery info" does not currently need to be calibrated. If the battery does need calibration this menu will actually say to calibrate it with the Canon charger. I want to calibrate my battery even though it "does not neet it" according to the menu on my 1ds iii body.<br>
