Each cell produces 2 V, so six cells are connected in series to produce a 12-V car battery. Lead acid batteries are heavy and contain a caustic liquid electrolyte, but are often still the battery of choice because of their high current density. The lead acid battery in your automobile consists of six cells connected in series to give 12 V.
Your cell should have a voltage equal to 1/6 th of the total battery voltage, assuming you have a typical 6-cell battery. For a 12 volt battery, that means you should get a reading of at least 2 volts from each cell. You''ll also likely be able to visually identify which cells are a problem because they will have different color plates from normal cells.

Not in a car because during charging the voltage exceeds 14 volt. A fully charged 12 volt battery will show higher than 12 volt for some time.
The lead acid battery generates electrical energy through a chemical reaction between its electrolyte fluid (consisting of sulfuric acid and water) and lead plates. Each time a battery discharges, lead sulfate crystals form on the battery plates. When the lead acid battery is recharged, the lead sulfate disperses. However, not all of it goes away.
