Notes: What We Measure & Why Individual block voltage – ensure correct charge and performance under load Individual block impedance – impedance change gives a solid life trend and end of life assessment. Ambient temperature at the cabinet/rack – high temperatures kill batteries. A 10°C increase gives a 50% decrease in life expectancy String current – allows detection of unbalanced strings, and provides rapid understanding of battery activity String voltage – confirmation of UPS operation & compliance with battery specification Individual block temperature [optional] – better knowledge of temperature gradients in cabinets; pre-empt thermal runaway P r o t e c t i n g y o u r p o w e r s u p p l y
