Unfortunately my MBP battery has undertaken some heavy damage to it somehow and it now has 110 cycles and doesn't hold its charge very well. I took it to the Apple store and they ran a diagnostic test which it failed. They said batteries aren't covered under warranty unless it is within the first year of purchase. I have Apple Care so I thought that that would have covered it. Obviously not I have 2 options: Buy one from Apple for £80-100 which is a bit steep. OR Buy a NON-OEM replacement battery for £30-40 from Ebay. I know which I'd rather go with because of the price but are they reliable and safe since they aren't 'certified' Apple components? Anyways, I'd like to hear your thoughts. Thanks!
