Be Careful: Battery Rating Lower than Listed Here!!
15 - 30 minutos
my girlfriend accidentally let the MBA drop against a sharp edge, which lead to the disfigurement of the battery within.
It's so straightforward, there isn't really anything to say about it. I did find out that the capacity rating is LOWER than the range 4900-5200mAh given here under "Product Details"
On ifixit.com it says that the battery you order, being used, might be "up to 300mAh" less. I took this to mean up to 300mAh less than the standard rating of a brand new battery, so in the range of 5200-300=4900mAh and 5200mAh, which would be just in the range given under "Product Details" on this same page.
But iFixit staff was brave to attempt some semantic gymnastics: I was told that the phrase "up to 300mAh less" is to be completed as: than the 4900mAh-5200mAh range given under "Product Details".
So on iFixit, "Product Details" do not mean details of the product on offer. Well...is that a nerdy way to be brazen?
In any case, according to this "logic", the battery you order here might have a capacity as low as 4900-300=4600mAh, rather than 4900mAh.
That may or may not be problem for you. But be aware.
