Lead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. Among the most critical problems are corrosion, shedding of active materials, and internal shorts.
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.
At present,it has become one of the maturest technical batteries.

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.
