Thanks for your advice, it works a bit. I started with a
max_charge : 597

After the first charge/drain it went up to 
max_charge : 1854

Strangely enough after a second cycle it's now
max_charge : 1573

I can't find a logic in this stuff... Do you think there's a special
reason why Apple uses such a complicated method instead of 
a) charging until voltage stays equals for a few minutes
b) draining until voltage goes under 13.5 volts (or 13, or whatever)

In my uninformed opinion that would work better, wouldn't it?
