10.626 Lecture Notes, Fuel cells and lead-acid batteries
2 Lead-Acid Batteries The open circuit voltage of a battery is more complicated than that of a fuel cell. This is because it must depend on the state of charge of the battery, which determines how much of each reactant and product is present, and hence their activities. One example of a battery is the lead-acid battery, used in cars.
Lead–acid battery fundamentals
The processes that take place during the discharging of a lead–acid cell are shown in schematic/equation form in Fig. 3.1A can be seen that the HSO 4 − ions migrate to the negative electrode and react with the lead to produce PbSO 4 and H + ions. This reaction releases two electrons and thereby gives rise to an excess of negative charge …

Fast Lead Acid Battery Charger Circuit
Thus a 6 V battery requires 6.9 V charging voltage while a 12 V battery requires 13.8 V. For fast charging of a lead acid battery using this circuit, the charging current does not need to be within the 0.1-1 C range (=capacity in Ah, actual figure differs with manufacturer). Instead when the charging current falls to 1% of its capacity, the ...

Now imagine that same battery, except with a 1 ohm internal resistance. With the same short, you get 1.1 ohms of resistance, or approximately 10.9 A. Big difference! This should line up with everyday experience. When you directly short a battery, you don''t get infinite current. You get it''s voltage divided by it''s internal resistance.
