# Car Battery Voltage Chart

Car battery voltage is a crucial factor in ensuring the optimal performance of your vehicle. It is important to understand the voltage levels of your car battery and how they relate to its ability to start your vehicle and power its electrical components. In this article, we will discuss car battery voltage and provide a car battery voltage chart to help you better understand the voltage levels of your car battery. We will also answer common questions about car battery voltage, including what is considered normal voltage, when voltage is too low, and whether 12.2 volts is okay for a car battery.

## Car Battery Voltage Chart

State of Charge (%) Voltage (12V) Voltage (6V)
100 12.7 6.35
90 12.6 6.30
80 12.5 6.25
70 12.4 6.20
60 12.3 6.15
50 12.2 6.10
40 12.1 6.05
30 12.0 6.00
20 11.9 5.95
10 11.8 5.90
0 11.0 5.50

It is important to note that these voltage levels may vary depending on the type and age of your car battery.

## What Is Car Battery Voltage?

Car battery voltage is the measure of the electrical potential of a car battery. It is important to understand the voltage of your car battery as it determines its ability to start your vehicle and power its electrical components.

## What is the normal voltage of a car battery?

The normal voltage of a car battery should be between 12.6 to 12.8 volts when the engine is turned off and no electrical components are in use. This is known as the battery’s resting voltage.

## Is 12.2 volts OK for car battery?

A car battery with a voltage of 12.2 volts indicates that it is partially discharged. While it may still be able to start your vehicle, it is recommended to recharge the battery as soon as possible to prevent further damage.

## What voltage is too low for car battery?

A car battery with a voltage of 11.8 volts or lower is considered to be critically low and may not have enough power to start your vehicle. It is important to recharge or replace the battery as soon as possible to avoid getting stranded.

## Conclusion

Understanding your car battery voltage is crucial for maintaining the health and performance of your vehicle. By regularly checking your battery’s voltage levels and referring to the car battery voltage chart, you can ensure that your battery is functioning properly and avoid unexpected breakdowns on the road.
