A 10-year total cost of ownership (TCO) analysis is provided showing li-ion is 39% less than VRLA despite their capital cost premium. A sensitivity analysis reveals the TCO drivers. Finally we discuss li-ion batteries for retrofit and new UPS applications and the effect of temperature on battery life, runtime, and cooling.

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.

When working with data center and commercial facility electrical systems, shocks of 100mA to more than 2,000mA are possible—definitely in the realm of serious harm to humans and property. Energized electrical equipment also presents the risk of arc flash caused by electrical faults that produce powerful explosions. When dealing with commercial and industrial electrical systems, such as uninterruptible power systems (UPSs) and their batteries, data center and facilities managers need to be aware of these risks, especially since some repair and maintenance procedures require working with a unit that is still energized. There are ways to minimize the risks to employees, equipment and the field technician performing the service. This paper answers some common questions about UPS maintenance, how to reduce the risks associated with servicing UPSs and batteries, and how to qualify a UPS service provider.
