Battery failure rates, as defined by a loss of capacity and the corrosion of the positive plates, increase with the number of discharge cycles and the depth of discharge. Lead-acid batteries having lead calcium grid structures are particularly susceptible to aging due to repeated cycling.
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.
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
The key to this revolution has been the development of affordable batteries with much greater energy density. This new generation of batteriesthreatens to end the lengthy reign of the lead-acid battery. But consumers could be forgiven for being confused about the many different battery types vying for market share in this exciting new future.
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 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.

BU-802: What Causes Capacity Loss?
Besides age-related losses, sulfation and grid corrosion are the main killers of lead acid batteries. Sulfation is a thin layer that forms on the negative cell plate if the battery is allowed to dwell in a low state-of-charge. If caught in time, an equalizing charge can reverse the condition.

Why Do Lead-Acid Batteries Fail? 5 Common Causes of Premature Battery …
Keeping a battery at a low charge or not allowing it to charge enough is a major cause of premature battery failure. According to Battery University, keeping a battery operating at a low charge (below 80%) can lead to stratification, where the electrolyte "concentrates on the bottom, causing the upper half of the cell to be acid-poor."
