The battery on my MacBook Air, model - A1466, is in dire need of replacement. I've been trying to do my research to find an efficient and affordable battery but frankly I'm a bit overwhelmed. Especially since I continue to read that many Amazon reviews are inaccurate. Can someone please recommend a replacement battery brand for the A1466 model? Ive looked at these brands: Egoway, GHM, IceTek, dynapak, ans NuPower. Please help me decide!
