Everytime I need to charge the battery on my Canon 1D Mark three I get a warning that calibration is recommended when charging battery the next time. Despite going through the very simple instructions the warning keeps reappearing each time I reload the battery. Recharge performance is three greens so I presume the back is not a problem. whilst I suppose it's not crucial it would be nice to get this slight annoyance sorted, any help greatly appreciated. first time on site looking forward to getting more involved.
