Hi, Need to change the battery on a mid 2013 MacBook Air 6.2, model A1466. Will change this out myself as iFixit procedure is straight forward. In the past I have purchased Ansanor branded batteries for PowerBook and MacBook Pro, and been highly satisfied. Cannot see they are available for the MBAir in question. I don't want a cheap (and potentially very uncheerful brand) that will be unreliable, so don't mind paying a premium price for a good one. Can anyone recommend an after-market brand they have purchased for a MacBook Air and been pleased with. I plan to purchase from Amazon.ca I note that several different brands/sellers offer 12 warranty, but Egoway and Lenoge batteries both offer an 18month warranty. Any positive comments on these?
