Is there a known issue with these batteries? It has a 2/5 star rating on the Apple website, so I can't be the only one with problems. It seems like they just stop working after a couple years. I am only 51 cycles in to this battery with 85% health, and it says "Replace Now". What? When I press the button on the battery, the lights do not come on. It does not charge at all. It just says "Not Charging - Replace Now". This is my third battery with this same problem. How does this happen? How is it so broken that it can't hold ANY charge?
