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? -- Colin
