Søstrene Grene Alkaline AAA
Cheap alkaline batteries from Anna and Clare. This chain of stores are mostly Danish, but there are a few shops all over the world. The shops have a selection/style like a pound or doller store, but not at fixed prices.
The discharge curves looks fairly good for an alkaline cell.
These batteries are fairly cheap, but performance is not bad.
