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
