How many is too many charging cycles for a laptop battery?
I'm thinking abut buying a used early 2009 Macbook Pro 15 at a college sale, so these will have been used by different students (one student per laptop though).
I have a 2006 Macbook Pro 17 that has 454 cycles, and using terminal it shows the "MaxCapacity" = 4746, "DesignCapacity" = 6300. It lasts a couple hours still, but when it dies, it is unable to sleep, and just shuts down. I'm hoping to avoid this with the newer laptop. So I'm wondering what the threshold is for replacement (so I can add that to the price if needed).
To see what your battery cycles/capacity are, in terminal use: ioreg -l | grep Capacity
