There can be several effects:
1. Meter parallax. Your photo shows almost 13V but in fact it is like 12.6 as you explained.
2. Absolute deviation. Analogue meters have fixed max. deviation, e.g. 2%. On your scale that would be 2% of 50V = 1V, so the real voltage will be between 11.6 and 13.6 (in this 2% example).
3. Charger inaccuracy. I don't know the accuracy of this charger. I have two of them, one shows 0.1V more than the other. I think 1% deviation is normal. In your case it could be more, but divided by 3 for a 3s lipo I wouldn't worry about it.

Just figured this out. The problem is not in the charger, its in the battery. 12v on my voltmeters and 13.XXv on the charger and on my kk2. Tried the output from a 5v mobile phone charger and both the accucell 6 and kk2 displayed 5v.
