16 Causes of Lead-acid Battery Failure
For ordinary lead-acid batteries, the electrolyte level decreases, exposing the upper part of the plate to the air; for valve-regulated sealed lead-acid batteries, it is the loss of water that reduces the saturation of the electrolyte in the diaphragm, making the plate ineffective. In contact with the electrolyte, the active material is vulcanized because it cannot participate in the reaction.

What causes a battery to short?
Shedded Material Accumulation: As mentioned earlier, active material that sheds from the plates can accumulate at the bottom of the battery case. If enough material builds up, it can form a conductive bridge between the plates, leading to an internal short. Detecting internal shorts early is crucial for preventing extensive damage to the battery.
How does a lead-acid battery shed?
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.
How does lead dioxide affect a battery?
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.
Why does a lead-acid storage battery lose its capacity?
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.
How does corrosion affect a lead-acid battery?
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.
