I'm trying to change the battery in a MacBook Air 11″ i7 1.8 GHz (July 2011) MD214LL/A.
I found this Runpower battery, which is 39Wh.
Yet when checking the specs mentioned above, the battery is a 35Wh.
If I change the battery to one with a higher Wh, will it have a negative impact or will it be ok?
Can I safely buy and install the new battery?
