Understanding the thermodynamic and kinetic aspects of lead-acid battery structural and electrochemical changes during cycling through in-situ techniques is of the utmost importance for increasing the performance and life of these batteries in real-world applications.
Lead-acid batteries naturally degrade as they age. One effect of this deterioration is the increase in resistance of the various paths of conductance of the internal cell element. The internal ohmic test units are generally designed to detect this internal change.
There were variations in the internal ohmic readings that were unrelated to the test variables. Based on the preliminary results of this study, it is recommended that internal ohmic readings not be used as the sole acceptance criteria for lead-acid batteries.
Capacity degradation is the main failure mode of lead–acid batteries. Therefore, it is equivalent to predict the battery life and the change in battery residual capacity in the cycle. The definition of SOH is shown in Equation (1): where Ct is the actual capacity, C0 is nominal capacity.
Impedance or admittance measurements are a common indicator for the condition of lead-acid batteries in field applications such as uninterruptible power supply (UPS) systems. However, several commercially available measurement units use different techniques to measure and interpret the battery impedance.

Based on the preliminary results of this study, it is recommended that internal ohmic readings not be used as the sole acceptance criteria for lead-acid batteries. Using these devices as the exclusive acceptance criteria could give false positives and could also miss minor defects that have not yet affected the cell to the point of cell failure.
