[* black] The battery's form factor seems 100% identical to the multi-lobed cell we found in the 2015 Macbook.
[* black] And yet somehow... a battery spec bump!
[* black]somehow, Apple managed to squeeze in a 4% capacity increase from the 7.55 V, 39.71 Wh battery in [guide|39841|last year's model|stepid=89847|new_window=true]. Apple claims this new 7.56 V, 41.41 Wh Li-ion power source should provide up to 11 hours of iTunes movie playback.

[* icon_note] We're guessing this capacity increase is owed to improved battery chemistry (though it's also possible that Apple's engineers have shaved away ''just'' enough material from the lower case to allow for a thicker battery).
[*[* black] Either wayUnfortunately, they did ''not'' squeeze in any of those nifty adhesive pull tabs we've seen in some [guide|52599|other|stepid=115488|new_window=true] [guide|48170|iDevices|stepid=107876|new_window=true].
[* icon_reminder] Regardless, our tests indicate this beefier battery is compatible with last year's MacBook. Nice!
