Apple 13" Intel Core i7 Retina Macbook Pro

Do these early 2013 refurbished MacBook Pro comes with new battery? I am sure the battery is the first to fail being 4 yrs old.

Battery is tested and replaced if needed.

I am also concerned about battery cycle. If I make purchase and received one with high battery cycle usage, do I have the option to return on unsatified refurbished condition?
