What is the end of life of a lead-acid battery?r. Thus, IEEE and other documents define the end of life of a lead-acid battery as the point at which the available capacity has fallen to 80% of rated capaci y.Figure 1 also shows the aging characteristics of nickel-cadmium batteri.
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.
What is a lead-acid battery?The lead-acid (PbA) battery was invented by Gaston Planté more than 160 years ago and it was the first ever rechargeable battery. In the charged state, the positive electrode is lead dioxide (PbO2) and the negative electrode is metallic lead (Pb); upon discharge in the sulfuric acid electrolyte, both electrodes convert to lead sulfate (PbSO4).
What are the major aging processes in lead-acid batteries?The major aging processes in lead–acid batteries are: Anodic corrosion (of grids, plate-lugs, straps, posts). Positive active mass degradation (shedding, sludging) and loss of adherence to the grid. Irreversible formation of lead sulfate in the active mass (crystallization, sulfation). Short-circuits. Loss of water.
What is the aging margin for lead-acid battery sizing?Upload your project docs. # Lead-Acid Battery Capacity Variation Throughout Service Life ## IEEE-485-2010 Standard: Aging Margin Justification The IEEE-485-2010 standard recommends including a 1.25 aging margin in lead-acid battery sizing calculations due to predictable capacity degradation patterns.
