Hi guys, the current Apple MBP batteries on the 15" are labelled as lasting for 1000 cycles. A cycle is defined by Apple as a 100% discharge and a 100% charge. When the battery is on 100% charge does it cut off the battery from the laptop when on AC power or does it continue to pull power from the battery and charge it up at the same time? So if I run a MBP on AC for 7hrs while at full charge does it count as a charge cycle? Thanks.
