As people would be familiar here, Macbooks in recent years have had a significant upgrade in battery life, and I'm here wondering if there's anyway for us using older Macbooks to get in on that some how. My question is can I put a battery from a 2014 model Macbook Air 13inch into my current 2011 model? I am aware that the extended battery life in the newer models are in no way solely attributed to the new battery, however if I can get a couple more hours out of a battery upgrade I feel its something worth trying. To be honest I am very happy with my current air and besides the rather lacking battery life there is no reason for me to upgrade to a newer model. Thanks to anyone who can weigh in on this.
