I have bought 3 of these laptops refurbished and 2/3 had batteries that were on their way out. My battery only lasts a few hours when a good condition oem one should last over 5. One battery was above 80% life according to a random shady "3rd party app" support told me to download so they wouldn't do anything for me. Not only that they gave me the runaround before outright denying me wasting everyones time... Basically plan on spending another 150+ on a battery if you buy a refurb macbook on amazon.
