The Basics of Battery Cells
A battery cell is the fundamental building block of a battery, consisting of a positive electrode (cathode), a negative electrode (anode), and an electrolyte solution that facilitates the flow of electrical charge. In a 12-volt car battery, the cells are typically arranged in a series-parallel configuration, with multiple cells connected in a specific pattern to achieve the desired voltage and capacity.
Types of Battery Cells
There are several types of battery cells used in modern automotive batteries, each with its own unique characteristics and advantages. The most common types of cells used in 12-volt car batteries are:
- Lead-Acid Cells: These cells use a lead-based alloy as the positive plate and a lead dioxide-based alloy as the negative plate. Lead-acid cells are the most widely used type of cell in automotive batteries due to their relatively low cost, high reliability, and well-established manufacturing process.
- Absorbed Glass Mat (AGM) Cells: These cells use a special type of glass mat to absorb the electrolyte solution, which helps to prevent spills and reduces the risk of corrosion. AGM cells are known for their high performance, long lifespan, and low maintenance requirements.
- Enhanced Flooded Battery (EFB) Cells: These cells use a modified flooded electrolyte solution that helps to improve the overall performance and lifespan of the battery. EFB cells are designed to provide a higher capacity and longer cycle life than traditional lead-acid cells.
- Lithium-Ion Cells: These cells use a lithium-based alloy as the positive electrode and a graphite-based alloy as the negative electrode. Lithium-ion cells are known for their high energy density, long lifespan, and low self-discharge rate, making them an attractive option for electric and hybrid vehicles.
Cell Configuration in a 12-Volt Car Battery
The cells in a 12-volt car battery are typically arranged in a series-parallel configuration, with multiple cells connected in a specific pattern to achieve the desired voltage and capacity. The most common configuration used in 12-volt car batteries is the 6-cell configuration, where six cells are connected in series to produce a total voltage of 12 volts.
Series Connection
In a series connection, the positive terminal of one cell is connected to the negative terminal of the next cell, creating a continuous flow of electrical charge. This configuration allows the cells to add up to produce a higher voltage, making it possible to achieve the desired 12-volt output. (See Also: How to Tell.if Your Car Battery Is Dead?

Advantages of Series Connection
- Higher voltage output: Series connection allows the cells to add up to produce a higher voltage, making it possible to achieve the desired 12-volt output.
- Improved reliability: Series connection helps to reduce the risk of cell failure, as the failure of one cell does not affect the overall performance of the battery.
Parallel Connection
In a parallel connection, the positive terminals of multiple cells are connected together, and the negative terminals are connected together. This configuration allows the cells to add up to produce a higher capacity, making it possible to achieve the desired ampere-hour rating.
Advantages of Parallel Connection
- Higher capacity: Parallel connection allows the cells to add up to produce a higher capacity, making it possible to achieve the desired ampere-hour rating.
- Improved durability: Parallel connection helps to reduce the risk of cell failure, as the failure of one cell does not affect the overall performance of the battery.
