No, they don't. If a cell is to continue living it has to continue to produce the energy needed to sustain its activities.
Cells store energy in bonds.
Cells store energy in the form of carbohydrates.
Plant Cells store energy in the complex carbohydrates such as starch, disaccharides, and lipids.Animal Cells store energy in the Polysaccharide known as Glycogen.Cells store energy when a third phosphate group becomes bonded to an ADP molecule. ATP molecules are a cell's basic energy source.
Cells store and release energy through the use of the mitochondria, an organelle contained within it.
Lipids are used for energy storage, cushions vital organs, and insulates the organism
Carbohydrates get and store energy in your cells.

they store energy in ATP and use it when the triphosphate bonds are broken
Chlorenchymatous cells in plants
One way is that they store it in bonds (E.G., ATP in its phosphate bonds).
Cells store starch (which can be used for energy) in plastids.
