Hi all, I recently bought a 2010 11 inch from the refurb store this week, and so far it's been great, but I have a question about the battery. When I checked the cycles not long after I turned it on, it said that the computer is 4 weeks old and that it had 39 battery cycles. Is this a normal amount of cycles for a refurb? It seemed a bit high to me, but it is a 2010 model, so I didn't know if this is normal for it's age or not.
