My camera tells me I need to calibrate my battery. Anybody had this before. I did a quick google search and couldn't find why. Just curious.

My 1d4 hasn't said this about any of my batteries so far, but my 1d3 did that once. I pushed the calibration option on the charger, and it said it completed successfully. But when I put the battery back in the 1d3, it still said it needed to be calibrated. I just ignored it after that.

The spare battery that I bought for my MK IV gave me that message. I followed the steps in my owners manual and the issue has not returned.

Have a look at your manual. Page 30 of the UK version.

Cheers, Oggy :)

It is so the camera can display properly the amount of juice left in your battery. Pretty simple actually.

In the index of your manual you can look up "Calibration" and it should point you to the place for what to do.

Two Canon cameras (5DC, 30D), three Canon lenses (24-105, 100-400, 100mm macro)

There is a button to press on the battery charger in the first few seconds after connecting it and the red Calibration needed light blinking. You press the button and it start calibrating - taking 10 hours instead of 2.
It's just a thing that's required once in a while to give you max performance out the battery. Nothing is wrong unless it keeps happening after each discharge.
The reason for the need? It doesn't matter :), it just needs to be done. Shouldn't be needed for a long time after it's done. When batteries near the end of their life, that's when it might start happening a lot.
