"Shorter-term storage like the used-battery banks his group studied may handle day-to-night needs, while longer-term storage can better mete out electrons over the course of cloudy or rainy days. Some ultra-long-term storage, he added, could even reserve extra amps during summer to dole out during winter’s shorter days." This might be a good strategy to recover costs and turn a profit, if demand and supply for battery storage remain constant. The MIT researchers are assuming that used battery banks sell for 60 percent of their original price. The researchers outline two challenges to including used batteries in the grid. The first one involves the scaling and scanning of such batteries. The second one is building an "all-purpose second-life battery system" that can be used for the effort.
