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.
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.
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode and Berndt , and elsewhere , .
