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 [1] and Berndt [2], and elsewhere [3], [4].The present paper is an up-date, summarizing the present understanding.
The path taken when current passes through the lead-acid cell will have resistance . This internal resistance depends on the cell''s design, construction, age and condition. On discharge this internal resistance (RC) causes the voltage measured across the cell''s terminals to be less than the EMF (E) of the cell (the voltage drop = I x RC, figure 3a). Thus when a current (I) …
How a lead acid battery is charged can greatly improve battery per-formance and lifespan.

To determine the recommended charging current for a lead acid battery, you need to know the battery''s capacity, voltage, and temperature. The charging current should be a fraction of the battery''s capacity, typically around 10-20% of the battery''s amp-hour rating. The charging voltage should also be adjusted according to the battery''s temperature, as higher …
The fundamental elements of the lead–acid battery were set in place over 150 years ago 1859, Gaston Planté was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid and subjected to a charging current, see Figure 13.1.Later, Camille Fauré proposed the concept of the pasted plate.

Although a lead acid battery may have a stated capacity of 100Ah, it''s practical usable capacity is only 50Ah or even just 30Ah. If you buy a lead acid battery for a particular application, you probably expect a certain lifetime from it, probably in years. If the battery won''t last this long, it may not be an economically viable solution.
