So go look on Apple's web site like the rest of us.

It's 77.5 Wh at 10.95 V. That's probably all you're going to get from
Apple.

Why does it matter to you, as long as it works correctly?

What is the ACTUAL PROBLEM here?

Jacobert-

I think that is your answer. Divide 77.5 Watt Hours by 10.95 Volts to
get 7.07762557 Ampere Hours, or 7077.62557 maH.

Jacobert-

As JR stated, that is probably the best you will be able to get from
Apple. I suspect they calculated 77.5 Wh by multiplying mAH by 10.95,
dividing by 1000 and rounding off.

Different laptops often use batteries with different voltages and have
different operating currents. Therefore Watt Hours are probably more
useful for comparing battery charge life. If you can find how much
power a given laptop uses, you can approximate its battery charge life
by dividing the battery's Watt Hours by the laptop's power requirement.

None of this means much.
