Incorrect. It has nothing to do with it.

 Wrong. But I don't fault you. Almost nobody understands the rating yet.
Capacity is the fundamental starting point of the Efficiency rating.

Ummmmm...no.

 The efficiency is exactly = RUNTIME HOURS PER AMP/HOUR of CAPACITY.
 Without the capacity, you can't calculate the efficiency. The EU's Energy
Efficiency Class (A–G) hinges on normalized battery capacity, specifically
how much runtime a device delivers per 1,000mAh of battery capacity.

And without runtime, you can't calculate efficiency either.
You're...
