Fig. 2 shows a comparison of power rating and the discharge duration of EES technologies. The characterized timescales from one second to one year are highlighted. Fig. 2 indicates that except flywheels, all other mechanical EES technologies are suitable to operate at high power ratings and discharge for durations of over one hour.
Electrical Equipment
Electrical equipment tends to be much more susceptible to damage than process equipment and structures. Scheffey et al. (1990) indicate that operating electronic equipment can be expected to fail at temperatures as low as 50 °C. They predict permanent damage to nonoperating equipment at 150 °C and failure of PVC cable at 250 °C.

Keep the freezer full but give the fridge some breathing space. Keeping the fridge about 70% full allows air to circulate and reduces air leaks when the door opens. Fix the seal if you are noticing condensation outside of the fridge. Doors not properly sealed are the most common energy drain for fridges.
