The battery has never been cycled. This brand new top case was installed on my late 2013 MacBook Pro Retina by Apple when I sent the laptop in for a repair.I have listed it as used since it was installed on my MacBook, although it wasn't used for longer than a day, so is essentially brand new. They thought it was the battery, so replaced the entire assembly. The problem turned out to be the logic board, but they gave the laptop back to me with the new top case assembly.
