These have poor power density, working well only at a steady state.
They also have a very high power density in the core, which requires special design features.
The lower frequencies at high power densities present a significant risk.
In practice, this means either not breeding or operating at a lower power density.
The batteries could have high power density and potential of 4.7 V per cell.
Some facilities have power densities more than 100 times that of a typical office building.
The power density necessary for this effect is however sufficient to also cause permanent damage.
In addition, the confinement time required depends on the power density.
A parts washer can be characterized by its power density.
A doubling of power density may not be out of the question.
