As usual with alkaline capacity varies with current drain and even this large cell cannot do much above 3A and have some capacity left.

Conclusion
The energy contents is 5-6 times a AA cell, but the current capability is not much higher.
Performance of this cell is similar to the other D cell I have tested when using low current and worse at higher current.
