What is acid stratification in a lead acid battery?
Accumulation of sulfuric acid at the bottom of the cell is called acid stratification. It can lead to faster sulfation, reduced capacity, and hence eventually battery failure. As a lead acid battery owner, you must know the details of acid stratification. As you know, lead acid battery electrolyte is a mixture of water and sulfuric acid.
What is lead acid battery electrolyte?
As you know, lead acid battery electrolyte is a mixture of water and sulfuric acid. Sulfuric acid is heavier than water. So, when the battery is not in use, the acid tends to settle down at the bottom of the cell. Stratification also occurs if the battery charge is regularly around 80-85%, not fully charged.
What causes lead-acid battery failure?
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.
Why does a lead-acid battery have a low service life?
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.
