Hello

The macbook air 11" / 2010 (A1370 model) , the battery is swollen and needs changing.

On removing the battery, it says - A1375 ( 020-6921-A)

I presume the A1375 is the battery part number?

I've seen variations of battery replacements on sale.

Does the battery have to be the exact same part number?

Or are there other newer batteries that can be used?

For example the A1406 battery?

Hello

I am curious to know, if anyone knows.

Viewing the batteries on offer here: http://www.newertech.com/batteries/

Would a mid 2011 macbook air 11" (battery part number A1406).

Work safely in a late 2010 macbook air 11" ? (Original battery part number A1375).

Whats the difference if any ?

The only difference I see is the part number. The connector plug to logic board, the 35wh wattages are the same as is the7.3 voltage.

Did apple just rename the part number between model years?

Can anyone confirm?

Thanks
