Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
Internal shorts represent a more serious issue for lead-acid batteries, often leading to rapid self-discharge and severe performance loss. They occur when there is an unintended electrical connection within the battery, typically between the positive and negative plates.
Battery degradation refers to the natural decline in a battery’s ability to store and deliver energy efficiently. Think of it like aging. Just as people grow older and less energetic, batteries also lose capacity and efficiency over time. This process occurs due to both chemical and physical changes inside the 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.
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 , . The present paper is an up-date, summarizing the present understanding.
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.
