Lithium-ion battery prices have decreased over the years and are now becoming a viable option for UPS applications. This paper provides a brief overview of li-ion batteries in comparison to VRLA batteries for singlephase UPS applications. A 10-year total cost of ownership (TCO) analysis is also provided showing li-ion is 53% less than VRLA despite their capital cost premium. A sensitivity analysis reveals the TCO drivers.
Battery Technology for Single Phase UPS Systems: VRLA vs. Li-ion
This paper provides brief overview of li-ion battery characteristics compared to VRLA. We then analyze the capital cost, operational cost, and total cost of ownership between these two battery types.
