Introduces the technical principles of VRLA-AGM valve-regulated sealed lead-acid batteries, including the gas recombination mechanism of the absorbed glass mat, pure lead grid structure, charge voltage and temperature range specifications, and their applications in data center UPS, telecommunications, and energy storage.
Explains the relationship between battery capacity, discharge rate and end voltage, covering rated capacity calibration conditions, capacity variation at different discharge rates, and the basis for setting end voltage with common application conventions.
Explains the 25°C nominal basis for VRLA battery float and equalizing voltages, the effect of temperature on charging voltage and life, and temperature management points for data center UPS, telecom and renewable energy scenarios.
