In summary, the failure of lead-acid batteries is due to the following conditions. Corrosion variant of positive plates. Alloys cast into the positive plate grid are oxidised to lead sulphate and lead dioxide during the charging process of the battery, which eventually leads to the loss of the supporting active substance and the failure of the ...
The following are some common causes and results of deterioration of a lead acid battery: Overcharging If a battery is charged in excess of what is required, the following harmful effects will occur: A gas is formed which will tend to scrub the active material from the plates.
Vibration Vibration is another major reason for battery failure. Excessive vibration can cause the battery’s internal plates to shift and become damaged, leading to a breakdown in the battery’s structure and causing short circuits within the battery. Vibration also accelerates corrosion, which leads to premature failure.
All lead-acid batteries will naturally self-discharge, which can result in a loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery’s electrolyte and the chemistry of the plates.
Lead acid batteries can last around 20 years or more if all conditions of operation are ideal. However, such conditions are not typically achievable. The end of battery life may be due to loss of active material, lack of contact of active material with conducting parts, or failure of insulation i.e. separators.
This number may be compounded by parasitic draw from the electronics in your vehicle. The longer your battery sits, the more it will discharge, leaving it open to sulfation and stratification. ADAC reports the number one cause of car breakdowns is battery failure, and that lack of use is a major culprit.
You may notice that your battery has a harder time starting, especially in cold weather, or the electrical systems begin to fail or malfunction. The most common cause of undercharged car batteries is frequent short trips. This is evident in the habits of Japanese drivers, where battery failure is the largest complaint among new car owners.

The end of battery life may result from either loss of active material, lack of contact of active material with conducting parts, or failure of insulation i.e. separators. These conditions may arise in a number of ways. The following are some common causes and results of deterioration of lead acid battery:
These crystals will lower the battery capacity significantly and lead to battery failure. 7. Electrolyte Contamination. Electrolyte contamination occurs when undesired elements find their way into the battery. Electrolyte contamination is not a problem in sealed and VRLA batteries but is a major problem in flooded lead-acid batteries.
The end of battery life may result from either loss of active material, lack of contact of active material with conducting parts, or failure of insulation i.e. separators. These …
The phenomenon called "sulfation" (or "sulfatation") has plagued battery engineers for many years, and is still a major cause of failure of lead–acid batteries. The term "sulfation" described the condition of a battery plate, in which highly crystalline lead sulfate has formed in an practically irreversible manner. This type of ...
5 Common Causes of Premature Battery Failure. The click of a dead battery is never a welcome sound, especially if your battery should have plenty of life left. Check out these common causes of lead-acid battery failure and what you can do about it. 1. Undercharging. Keeping a battery at a low charge or not allowing it to charge enough is a ...
Catastrophic failure is attributed to incorrect cell design, poor manufacturing practice, abuse, or misuse. These problems are obvious and, accordingly, have been afforded little discussion....
Lead-acid battery capacity loss can be attributed to several factors, often related to the battery''s operating conditions, maintenance, and chemical processes. Sulfation: …
The delivery and storage of electrical energy in lead/acid batteries via the conversion of lead dioxide and lead to, and from, lead sulphate is deceptively simple. In fact, battery performance ...
In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short. In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification. Acid stratification occurs in flooded lead acid batteries which ...
Over discharge leads to hydration. Hydration occurs in a lead-acid battery that is over discharged and not promptly recharged. Hydration results when the lead and lead compounds of the plates dissolve in the water of a discharged cell and …
1. Lead-Acid Batteries. In flooded lead-acid batteries, electrolyte loss primarily occurs through gassing during the charging and discharging processes. When the battery charges, hydrogen and oxygen gases form, which can escape into the atmosphere. This loss of gas results in a concentration of the remaining electrolyte, diminishing its ...

Hydration occurs in a lead-acid battery that is over discharged and not promptly recharged. Hydration results when the lead and lead compounds of the plates dissolve in the water of a discharged cell and form lead hydrate, which is deposited on the separators.

In flooded lead–acid batteries, roughly 85% of all failures are related to grid corrosion, while in valve-regulated lead–acid batteries, grid corrosion is the cause of failure in about 60% of cases. This is a problem that develops over time and it typically affects batteries that are close to end of life. In other words, if the preventable causes of failure are eliminated, then …
