Which replacement battery for Macbook Air 2011 is equal to or better than the original?
I need to replace a battery for my Macbook Air 13" mid-2011, and I'm fairly savvy with electronics to do my own repairs.
I assume that Apple is very unlikely to allow any retailer to sell Apple's genuine battery for Air. What are alternatives which are equal to or better than the original batteries? What are their product IDs (or how can I identify it otherwise, especially if ordering online)?
By "equal or better" I mean that it lasts at least as many cycles. I.e. after equal number of charges, it keeps Macbook running roughly as long as the genuine battery on a single charge, given the equal load.
