How much energy does a lithium ion battery store?
A lithium-ion battery usually stores 30 to 55 kilowatt-hours (kWh) of energy. For instance, a 1 kWh battery can supply about 200 amp-hours (Ah) at 12 volts (V). Modern lithium-ion batteries have energy densities ranging from 200 to 300 watt-hours per kilogram (Wh/kg), which greatly affects their production capacity.

How long does a battery storage system last?
For instance, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity can provide power for four hours. The cycle life/lifetime of a battery storage system determines how long it can provide regular charging and discharging before failure or significant degradation.
What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability of a battery energy storage system (BESS), or the maximum rate of discharge it can achieve starting from a fully charged state. Storage duration, on the other hand, is the amount of time the BESS can discharge at its power capacity before depleting its energy capacity.
