This means that a battery frequently discharged to 80% may have a shorter lifespan compared to one typically discharged to only 50%. This relationship is crucial in batteries like lithium-ion and lead-acid, both commonly used in solar applications. For example, lithium-ion batteries generally offer longer cycle lives and tolerate deeper

The need for energy storage. Energy storage—primarily in the form of rechargeable batteries—is the bottleneck that limits technologies at all scales. From biomedical implants and portable electronics to electric vehicles [3– 5] and grid-scale storage of renewables [6– 8], battery storage is the primary cost and design limitation
Think about the example above of the difference between a light bulb and an AC unit. If you have a 5 kW, 10 kWh battery, you can only run your AC unit for two hours (4.8 kW 2 hours = 9.6 kWh). However, that same battery would be able to keep 20 lightbulbs on for two full days (0.012 kW 20 lightbulbs * 42 hours = 10 kWh).

With each utilization of the battery, a proportion of this ''water''—or, more accurately, stored electrical energy—is depleted. The Depth of Discharge provides a metric, denoting the percentage of energy that has been drained from the battery. A higher DoD percentage indicates a more substantial depletion of the battery''s total capacity.
