Also 1500 installations and 6 years of field testing? Could be legit?

What is the energy/power density of these? I mean, generally, they should be better than Lithium Ion but it could be different for these particular types of cells.
Also it seems like Zinc Air batteries usually are not very efficient (only 50% efficiency vs 80+ for other types). Wonder if this applies to them as well.

General ranges via wikipedia:

Lithium ion:
Energy density: 250–693 W·h/L (0.90–2.43 MJ/L)
Specific energy: 100–265 W·h/kg (0.36–0.875 MJ/kg)

Zinc air:
Energy density: 1480-9780 Wh/L (5.328–35.21 MJ/L)
Specific energy: 470 (practical),1370 (theoretical) Wh/kg (1.692, 4.932 MJ/kg)

However, the fact that they have supposedly been testing these batteries in applications that don't require high energy density certainly makes me question that their batteries are. Add to that the fact that they are touting manufacturing price, but say nothing of density. Perhaps the breakthrough that prevents degradation requires that the batteries are significantly less dense than zinc-air batteries otherwise would be?

This was fluidic energy and they are (was) a very reputable company
