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.

This paper provides an analysis of the reliability of Active Power's flywheel-based UPS system vs. a battery-based double-conversion UPS system.

In a mixed media experience, we share a story about how Interstate Batteries moved away from manual processes and transformed HR with Workday.

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.

This paper provides a quantitative analysis of the in-service reliability of Active Power’s CleanSource 750HD UPS (uninterruptible power supply) system versus a double-conversion UPS with batteries.
