From what I've seen all carbon-zinc cells say "heavy duty" or "extra heavy duty" regardless of brand. It was discussed why here before I think.

I thought those "D" batteries looked a bit small, but it's hard to tell from a 2D photo. Still they'll probably be effective, I doubt the average person is gonna notice the marking.

Extra Heavy Duty == zinc chloride. And the "Miracle Seal" really does work: I have a remote control from the 1980s with those Radio Shack cells: they were probably never changed, and they still hold a charge and never leaked.
It should be noted that the current capability of even "extra heavy duty" is meager compared to alkalines, but their longevity is a benefit in low-drain applications like remote controls.
Daixiwen:
The Duracell is not leaking. It's obviously a fake
TheNewLab:
The CVS AA which is really a triple size battery
Good one
