The following mainly analyzes the lead-acid battery short circuit caused by excessive charging current, charging voltage of a single battery exceeds 2.4V, internal short-circuit or partial discharge, excessive temperature rise and valve control failure, and summarizes the treatment methods of lead acid battery short circuit as follows:
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. As more material sheds, the effective surface area of the plates diminishes, reducing the battery’s capacity to store and discharge energy efficiently.
Many of the float charge and discharge voltages of lead-acid batteries in UPS power systems have been adjusted to their rated values at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as control of the number of computers and other electronic equipment.
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
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.
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.

Lead–Acid Batteries
A lead–acid battery cannot remain at the peak voltage for more than 48 h or it will sustain damage. The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V. This stage of charging is also called "absorption," "taper charging," or ...

What are common battery failures?
When a lead-acid battery is left to self-discharge (in storage or installed but seldomly used) or is exposed to excess and repeated high-rate charging (such as is the case with Start-stop vehicles), a point can be reached where the reaction at the negative plate that should convert the lead back to active material (PbSO4 back to Pb) cannot ...

Why is acid stratification the principal case of lead-acid batteries ...
Stratified acid promotes increased internal resistance, lower conductivity and accelerated sulfation on the lower part of the plates, reducing the battery''s dynamic charge acceptance. This means a sulphated battery will only accept a surface charge, resulting in a false positive state of charge readings to vehicle computers and battery testers.

Understanding Lead Acid Battery Explosions Risks
Key Causes of Lead Acid Battery Explosions. Overcharging: One of the most common causes of lead-acid battery explosions is overcharging. When a battery is charged beyond its capacity, the excess electrical energy converts into heat rather than chemical energy. This leads to the decomposition of water in the electrolyte into hydrogen and oxygen gases. If …

Several Causes of Lead-acid Battery Failure -
In summary, the failure of lead-acid batteries is due to the following conditions. 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 battery.
