Macbook air 11 2010 battery replacement

[xiaomei]

Does anyone know if Macbook Air 11 late 2010 and 2011 share the same battery type? I want to replace the battery and I'm not sure if it's the same part number. All I know is that 2012 is different type from 2010.
Anyone performed this himself?

iFixit is showing different part numbers for those two.

Thanks. That should be an answer to my question.
