Lead sulfate is formed due to chemical reaction between the lead plates and the sulfuric acid during the normal discharge of a lead acid battery. While recharging, lead sulfate is dissolved back into the electrolyte but a small fraction adheres to the battery plates and subsequently hardens the lead sulfate on the battery plates.

Common Causes of Lead-Acid Battery Failure Sulfation. Sulfation occurs when a lead-acid battery is left in a discharged state for too long. During this period, lead sulfate crystals form on the battery''s plates. Irregular use, such as leaving a battery idle for long periods, can lead to problems like self-discharge and sulfation. Even
However, one drawback of this battery type is that the inherent thermodynamics of the battery chemistry causes the battery to self-discharge over time.

If a battery is subjected to deep discharging (greater than 35%) and rapid charging the process is accelerated. Additionally if the recharge does not recover the discharge cycle in full, the battery will exhibit loss of performance and concentration of the acid can occur between plates which can lead to corrosion and loss of performance.

Cold temperatures can severely limit the battery''s ability to discharge energy. As temperatures dip below freezing, the internal resistance of the battery increases.
Lead-acid storage battery will lose part of its capacity due to self-discharge. Therefore, before lead-acid battery is installed and put into use, the remaining capacity of the battery should be judged according to the battery's open circuit voltage, and then different methods should be used for supplementary charge for the battery.

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.
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
Over discharge 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 form lead hydrate, which is deposited on the separators.
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.
