the replacement's poweron time on a single charge will be the same (or ideally better) than how could original battery installed by Apple service perform, at (most) every point in the battery life.the replacement will last comparable number of recharge cycles as the battery installed by an official Apple service.The sales rep couldn't provide any tests proving the 'with better life' statement, nor even confirm that such tests were ever performed: 'Unfortunately I do not have any tests to show as we have found those to not be needed'Ĭould not confirm that any part of these statements are true: I failed to get any comment on how it can be possible that Apple allows its manufacturer to sell parts that Apple itself doesn't normally sell (which is the case for MBA-2011 batteries).there's 6-month warranty for a case if it performs poorly at customer's computer.its initial power-on time on a single charge is better compared to the original battery: 'buying a brand new battery will get you back to where your computer was when you first bought it'.manufactured by the same company that manufactures Apple's battery.I didn't find any 'most robust and lasting' choice yet, but I contacted iFixit re their replacement battery, and this is what I found out.
