A battery is degraded by the superposition of the various degradation modes (sulfating, stratification, corrosion and non cohesion of active mass). Fig. 14, Fig. 15, Fig. 16 represent the experimental Nyquist diagram of 3 batteries (a new battery and 2 used batteries). Fig. 14. Diagram of Nyquist of the battery tested No. 1. Fully charged.

The lead acid battery technology has undergone several modifications in the recent past, in particular, the electrode grid composition, oxide paste recipe with incorporation of foreign additives into the electrodes and similarly additives added in the electrolytes to improve electrical performance of the lead acid battery.
The major aging processes, leading to gradual loss of performance and eventually to the end of service life, are stratification of electrolyte, sulfating of the electrodes, corrosion of the electrodes and the loss of active mass adherence to the grid , , . Fig. 1. Causal tree of lead acid battery.
Availability, safety and reliability issues—low specific energy, self-discharge and aging—continue to plague the lead-acid battery industry, 1 – 6 which lacks a consistent and effective approach to monitor and predict performance and aging across all battery types and configurations.
The reliability analysis of the lead acid battery is based on three stages. The first stage consists of constructing a causal tree that presents the various possible combinations of events that involves the batteries degradation during lead acid battery operation .
On the other hand, at very high acid concentrations, service life also decreases, in particular due to higher rates of self-discharge, due to gas evolution, and increased danger of sulfation of the active material. 1. Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.

Based on the materials characterization results, we found that the degradation of a lead-acid battery is influenced by the amount of hard sulfate and the sulfate particles'' size. Previously, premature capacity loss (PCL) has been generally interpreted as a discharge inhibition of the positive electrode.
