To test your car’s battery voltage, you will connect a multimeter to the negative terminal, then the positive terminal. Alternatively, if you have it available to you, a load test is a reasonable way to test a car battery’s voltage.īefore your test, make sure that your battery terminals are free from corrosion. This simple device measures the voltage of a car battery. You don’t need to know anything, you just need a measuring device, a multimeter. How To Test Car Battery VoltageĬhecking whether your car battery is working properly is an easy task that any car owner can do. Anything below that means you need to change the battery. Readings like 13.2 V – 13.4 V means your car battery should be checked out. With the engine running, 14.0V – 14.8V measurements are acceptable. When the engine running, the multimeter readings will tell you whether the charging system and alternator is operating properly. So, your car battery can be at 0% status charge but still start. Keep in mind, 10.5 V is the minimum voltage needed to start the car. The state of charge should go back 80% – 100% with a turned-off engine. However, once you go for a drive, and the battery charges up. Or, theres freezing cold weather and you haven’t started your car in a while. Weaker readings are acceptable only if you forgot your headlights on. That means the car battery readings you are looking for are 12.42 V – 12.7 V when the engine is not running. Ideally, you want your car battery to always be at 80%-100% charge. This chart will help you read multimeter measurements better. When the car is running, the battery should be charging somewhere between 13.7 Volts – 14.7 Volts. No matter the type of car battery, a healthy car battery charges at 12.6 Volts or higher. The multimeter will show the current voltage reading from the car battery. This voltage will increase when the car is running, but should typically have 12.6 volts of resting voltage. In short, car batteries are typically 12v (12 volt) units. What Is Good Car Battery Voltage?
