I had just visited the apple store for service, I was told my battery could not be replaced as I was out of warranty (2011 macbook pro). However I was looking over battery replacement policies and it states that defective batteries are covered one year after your warranty expires. The diagnostics showed that I had ~190 cycles but somehow the battery was COMPLETELY depleted, this sounds to me like a defective battery yes?
Apple will provide a warranty against hardware defects on the replacement battery for one year from the date of the Out of Warranty service. Please note that the battery is a consumable item and after a period of normal use the battery's ability to hold an electrical charge will be diminished. A replacement battery that has failed because it has been consumed via normal use is not covered under warranty.
