Depending on the battery type, charge–discharge cycle can be repeated many times, from about 500 cycles for popular lead–acid batteries to over 10,000 cycles for typical flow batteries. As a result of their ability to be recharged, secondary batteries can function as electrical energy storage devices, also called accumulators.
