AI Customer ServiceNevertheless, 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.
On the other hand, at very high acid concentrations, service life also decreases, in particular due to higher rates of self-discharge, due to gas evolution, and increased danger of sulfation of the active material. 1. Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.
Results obtained indicate that in most cases, battery failure was responsible for the collapse of the system. Earlier works indicate that under-charging, over-charging and over-discharging are common causes of premature failure of batteries .
Irreversible formation of lead sulfate in the active mass (crystallization, sulfation) The phenomenon called “sulfation” (or “sulfatation”) has plagued battery engineers for many years, and is still a major cause of failure of lead–acid batteries.
In order to avoid the described problem, valve-regulated lead–acid batteries are often maintained at an excessively high float voltage, again with correspondingly adverse effects on grid corrosion, as already mentioned.
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.
