Agree. My current battery in my Macbook Pro reports 85-88% health. That&#x27;s a significant loss but my laptop is long overdue for an update (when Apple will finally get of their ass and make a new MBP). Stopping the battery deterioration is neat but if it isn&#x27;t cheap, it wouldn&#x27;t be worth it.<p>I&#x27;d rather see extended capacity.
