I bought a new 15" macbook pro in June of 2011 for University. Two years later, there is a service battery warning stating my battery health is low. I checked the iStat Battery health and it says 52% health at 400 charge cycles. I was under the impression that these new batteries were supposed to hold 80% charge at 1000 cycles, over twice my cycles. The laptop is not under warranty but it seems like the battery is clearly defective. Do you think apple will replace it for free?
