Lead-acid battery internal resistance decay

EILR

Internal resistance or impedance measurements are a common method to assume the condition of a lead-acid battery. The readings could lead to predictions about the state-of-charge (SoC) and/or state-of-health (SoH) condition of a battery without the necessity of performing a full charge/discharge cycle. In practice, the readings

Internal Resistance: Harbinger of Capacity Loss in Starved

The impedance rise, which is observed to be log-linear with time on float, is accompanied by a linear loss of cell weight due to water loss. The results suggest that battery impedance may provide a useful diagnostic for sealed lead acid batteries if simple calibration experiments are performed on cells of the type to be monitored.
