The anodic corrosion, positive active mass degradation and loss of adherence to the grid, irreversible formation of lead sulfate in the active mass, short circuits and loss of water are the major aging processes. The overcharge of the battery lead to accelerated corrosion and also to accelerated loss of water.
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode and Berndt , and elsewhere , . The present paper is an up-date, summarizing the present understanding.
The discharge capacity and the model parameters are updated by an ageing model, whose inputs are the terminal voltage and the state of charge. Sauer and Wenzl ( 2008) have compared three ageing models for lead-acid batteries: the physico-chemical ageing model, the weighted Ah ageing model, and the event-oriented ageing model.
Křivík et al. ( 2021) have investigated the effect of the ageing process on the lead-acid battery impedance by means of electrochemical impedance spectroscopy. They have concluded that the ageing process has a significant influence on the impedance modulus and phase during the battery life.
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.
We have verified that the battery ageing may be modelled as function of the number of cycles performed, which is equivalent to that seen in the field and not the time it takes the battery to reach its end of life.

Lead Acid Battery
A lead-acid battery is an electrochemical battery that uses lead and lead oxide for electrodes and sulfuric acid for the electrolyte. Lead-acid batteries are the most commonly used in PV and other alternative energy systems because their initial cost is lower and because they are readily available nearly everywhere in the world. There are many different sizes and designs of lead …
