A lead acid battery is made up of a number of cells. Each cell has a positive and negative plate, separated by an electrolyte. The number of cells in a lead acid battery depends on the voltage rating of the battery. For example, a 12-volt battery will have six cells, while a 24-volt battery will have twelve cells.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
The active circuit parts of a lead-acid battery cell include several components. The negative electrode is made of lead (Pb), while the positive electrode is made of lead dioxide (PbO2). The electrolyte used is typically a 5M H 2 SO 4 aqueous solution. A porous glass mat filled with electrolytes acts as a separator between the two electrodes.
Different versions of the lead-acid battery are wet cell (flooded), gel cell, and absorbed glass mat (AGM). There are two styles of wet cell; serviceable and maintenance-free. Both are electrolyte-filled and are basically the same.
These batteries are commonly referred to as SLI (starting, lighting, and ignition) batteries, reflecting their primary functions in a vehicle. The active circuit parts of a lead-acid battery cell include several components. The negative electrode is made of lead (Pb), while the positive electrode is made of lead dioxide (PbO2).
Typical parameters for a Lead Acid Car Battery include a specific energy range of 33–42 Wh/kg and an energy density of 60–110 Wh/L. The specific power of these batteries is around 180 W/kg, and their charge/discharge efficiency varies from 50% to 95%.

6.10.1: Lead/acid batteries
The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O. Overall: Pb + PbO 2 +2H 2 SO 4 → 2PbSO 4 + 2H 2 O. During the …
Lead–acid battery fundamentals
For many years, it was thought that lead–acid batteries of any type could not be fast charged because there would be irreparable damage to the positive active-material. In the early 1990s, however, researchers at Cominco in Canada showed that a variant of the current-limited CV method, in which a so-called ''resistance-free voltage'' was used, could rapidly …
