I have a MBA 11 Early 2014.
Bought in July 2014.
The battery had around 380 cycles and was at around 83%.
But it used to last 3-5 hours of super light usage and was also overheating.
Went to Apple and asked for a fresh battery at my expense.
They obliged.
The battery life has more than doubled. It is 8-10 hours or super light usage.
Mojave in both instances.
