Solved Battery Capatible Does It Fit Each Other Macbook Air 11 Late 2010

Chosen Solution

My previous mac battery has 7.3v 50wh But 7.6v 54.4whr replacement battery can be fit on it? Both batteries has written as Model:A1377

If both batteries have the same model number, yes it will work. Usually, suppliers sell batteries which are compatible for 2010-2015 MacBook Airs, even though they originally are not compatible. They have a difference in the voltage, but it will work fine as long as it has the same model number as the original battery.
