Battery in series is a popular configuration in the world of electronics. When you connect batteries in series, you connect the positive terminal of one battery to the negative terminal of another battery, creating a row or sequence of batteries. This configuration allows you to increase the voltage of the batteries, while the capacity remains the same.
Imagine you have one battery with a voltage of 1.5 volts. Now, if you connect another battery in series with the first one, you will have a total voltage of 3 volts. Each battery adds its voltage to the one in front of it, resulting in a cumulative increase in voltage. This is particularly useful when you need a higher voltage for your electronic devices.
In a scenario where you have four batteries connected in series, the positive terminal of the first battery is connected to the negative terminal of the second battery. The positive terminal of the second battery is connected to the negative terminal of the third battery, and so on. This creates a continuous chain where the voltages of all the batteries add up after one another, creating a higher total voltage.
It’s important to note that when you connect batteries in series, the overall capacity of the batteries remains the same. The capacity is determined by the individual battery and is not affected by the connection. So, if you have four batteries with a capacity of 1000mAh each, the total capacity when connected in series will still be 1000mAh.
Battery in Series: Basics
When batteries are connected in series, they are placed in a row, one after another, in a sequence.
In a series connection, the positive terminal of one battery is connected to the negative terminal of another battery, thereby creating a continuous pathway for the flow of electric current.
When batteries are connected in series, the total voltage is the sum of the individual voltages of each battery. The total capacity, however, remains the same as that of a single battery.
It is important to note that when batteries are connected in series, the current passing through all the batteries is the same. Therefore, if one battery in the series connection fails or is weaker than the others, it can affect the overall performance of the entire series.
| Battery 1 | Battery 2 | Battery 3 |
|---|---|---|
| Positive Terminal | Negative Terminal | Positive Terminal |
| 1.5V | 1.5V | 1.5V |

Effect of Series Connection
When batteries are connected in series, they are attached one after another in a sequence, creating a row of connected batteries. This arrangement increases the voltage of the overall battery pack.
Increased Voltage
In a series connection, the voltage of each battery adds up to give a higher total voltage. For example, if two 12-volt batteries are connected in series, the total voltage will be 24 volts.
Same Current
When batteries are connected in series, the current passing through each battery remains the same. The total current flowing through the series connection is the same as the current flowing through each individual battery.
It is important to note that while connecting batteries in series increases the voltage, it does not affect the capacity or energy storage of the batteries. The overall capacity of the battery pack remains the same as that of a single battery in the series.
Increased voltage
When batteries are connected in series, the voltage of each battery is added together to create a higher overall voltage. This is because the positive terminal of one battery is connected to the negative terminal of the next battery in the series. In this configuration, the positive terminal of the first battery is connected to the negative terminal of the second battery, and so on, until the last battery in the row.
For example, if two 1.5V batteries are connected in series, the total voltage will be 3V. Similarly, if three 1.5V batteries are connected in series, the total voltage will be 4.5V, and so on. This increased voltage can be useful in applications where a higher voltage is required, such as in some electronic devices or power tools.
| Battery | Voltage |
|---|---|
| Battery 1 | 1.5V |
| Battery 2 | 1.5V |
| Total voltage | 3V |
It is important to note that when batteries are connected in series, the capacity and energy of the batteries remains the same. However, the increased voltage allows for the delivery of more power to the device or circuit being powered.
Unchanged capacity
When batteries are connected in series, their capacity remains unchanged. This means that when one row of batteries is connected to another in a series, the total capacity of the batteries is still the same.
For example, if you have one battery with a capacity of 1000mAh and another battery with a capacity of 2000mAh, when they are connected in series, the total capacity will still be 3000mAh.

It’s important to note that while the capacity remains unchanged, the voltage and power output of the batteries do change when they are connected in series. The voltage increases, as it is the sum of the voltages of the individual batteries, and the power output also increases accordingly.
So, when you connect batteries in series, you can still benefit from their combined capacity, while also obtaining a higher voltage and power output.
Effects on overall battery life
When batteries are connected in series, they are arranged in a sequence where the positive terminal of one battery is connected to the negative terminal of another battery, and so on in a row. This arrangement increases the overall voltage of the batteries but does not affect their individual capacity.
Increased Voltage
Connecting batteries in series increases the overall voltage because the voltage of each battery adds up. For example, if two 1.5V batteries are connected in series, the overall voltage would be 3V (1.5V + 1.5V = 3V). This increased voltage can be beneficial when using devices that require higher voltages to operate.
Unchanged Capacity
While connecting batteries in series increases the overall voltage, it does not affect their individual capacities. Each battery still retains its original capacity, meaning that the total amount of charge that can be stored in the batteries remains the same. However, it is important to note that the batteries may drain at different rates due to internal resistance or uneven charge distribution.
In summary, connecting batteries in series can increase the overall voltage while maintaining the individual capacity. This can be advantageous in certain applications but it is important to consider factors such as battery drain and compatibility when using batteries in series.

|---|---|
| The voltage adds up | The voltage stays the same |
| The current stays the same | The current adds up |
When it comes to batteries, the series connection increases the total voltage, which can be useful for applications that require a higher voltage. On the other hand, the parallel connection increases the total current, which can be beneficial for applications that require a higher current.
Understanding the difference between series and parallel connection is important when working with batteries, as it can affect the overall performance and suitability for specific applications.
Comparison of voltage and capacity
When it comes to batteries, there are two important factors to consider: voltage and capacity. These two factors determine the performance and suitability of a battery for different applications.
Voltage:
Voltage is a measure of electric potential difference between two points. In a battery, each cell produces a certain amount of voltage. When multiple cells are connected in series, the voltages of each cell add up to give the total voltage of the battery.
For example, if you connect two cells in series, each with a voltage of 1.5 volts, the total voltage of the battery will be 3 volts. Similarly, if you connect three cells in series, each with a voltage of 1.2 volts, the total voltage of the battery will be 3.6 volts.
Capacity:
Capacity refers to the amount of energy a battery can store. It is typically measured in ampere-hours (Ah) or milliampere-hours (mAh). When batteries are connected in series, the capacity of each battery remains the same, but the total capacity of the battery bank increases.
For example, if you connect two batteries, each with a capacity of 1000mAh, in series, the total capacity of the battery bank will still be 1000mAh. However, the voltage of the battery bank will increase according to the number of batteries connected in series.
When choosing a battery for a specific application, it is important to consider both voltage and capacity. Higher voltage batteries are suitable for applications that require more power, while higher capacity batteries are better for applications that require longer runtimes.
In summary, when batteries are connected in series, the voltage adds up, while the capacity remains the same. This allows for increased voltage and power output, making series-connected batteries ideal for a wide range of applications.
Choosing the right connection
When it comes to connecting batteries in series, there are a few factors to consider in order to choose the right configuration for your specific needs.
Capacity and Voltage
One of the most important factors to consider is the capacity and voltage requirements of your application. If you need a higher capacity, you can connect batteries in series to increase the overall capacity. This is achieved by connecting the positive terminal of one battery to the negative terminal of another battery.
For example, if you have two 12V batteries with a capacity of 100Ah each, connecting them in series will give you a total voltage of 24V and a capacity of 100Ah.
Sequencing
Another factor to consider is the sequencing of the batteries. The order in which the batteries are connected can have an impact on the overall performance and reliability of the system.
It is generally recommended to connect batteries of the same type and capacity in series. This ensures that the batteries have similar characteristics and will discharge and charge at the same rate.
When connecting batteries in series, it is important to connect the positive terminal of one battery to the negative terminal of another battery in a consistent sequence. This means that all positive terminals should be connected to negative terminals in the same row.
For example, if you have three batteries, labeled A, B, and C, you should connect them in the following sequence: A positive to B negative, B positive to C negative.
By following this sequence, you ensure that the batteries are connected in the correct polarity and that the overall voltage is increased in a consistent manner.
In summary, when choosing the right connection for batteries in series, consider the capacity and voltage requirements of your application, and make sure to connect the batteries in the correct sequence to ensure optimal performance and reliability.
Combining series and parallel connections
When it comes to combining battery connections, there are two common configurations: series and parallel.
Series connections
In a series connection, batteries are connected one after another in a row. This means that the positive terminal of one battery is connected to the negative terminal of another battery.
When batteries are connected in series, the voltages add up. For example, if you connect two 2-volt batteries in series, the total voltage will be 4 volts.
Parallel connections
In a parallel connection, batteries are connected side by side, with the positive terminals connected together and the negative terminals connected together. This means that the positive terminals of all the batteries are connected in parallel, and the negative terminals are also connected in parallel.
When batteries are connected in parallel, the capacities add up. For example, if you connect two 1000mAh batteries in parallel, the total capacity will be 2000mAh.
By combining series and parallel connections, you can create more complex battery configurations to meet specific power requirements. For example, you can connect batteries in series to increase voltage and then connect these series groups in parallel to increase capacity.
