When you want to make your car run, what's the first thing that comes to mind? You guessed it! A healthy battery.The best way for your car to have a long life is by taking care of its battery, that’s why it’s a crucial step to routinely check your battery’s voltage. Checking the state of charge of a car battery is vital to avoid problems in your vehicle. Because of this, regular battery maintenance should always be on your priority list especially if you use it on a daily basis. However, some people ignore it for a long time — not until they notice an issue with their cars. But even if you're not experiencing any issues, it's smart to take readings and make sure that everything is in order. A high or low voltage can mean serious problems with your engine and electrical system. In this article, you will learn how to properly check your car battery voltage with or without using a multimeter. By following the instructions below, it will help you determine your battery’s problems ahead of time.
But First, How Many Volts Should a Well-Conditioned Car Battery Have?The voltage of a well-conditioned car battery will vary depending on the temperature, the number of days it has been in storage, and even its design. A healthy and perfectly working car battery should have at least 12.6 to 12.9 volts. But to get a really accurate reading, the car battery must be in a “resting voltage”. To achieve this, it’s best to leave the car overnight and check the battery health before using the car in the morning. However, if you can’t wait overnight and need to test the battery after a drive, let it sit for at least an hour before doing so. It may not be as perfectly accurate but it will still reach the resting voltage phase. In addition, the voltage of a well-conditioned car battery will vary depending on the temperature, the number of days it has been in storage, and even its design. Utilizing a Multimeter to Check the Battery VoltageA multimeter or a battery tester is needed to check the precise voltage of your car battery. This item is relatively cheap and is a very useful tool for car owners and enthusiasts. Listed below are the steps to check your car battery's voltage using a multimeter:
Testing the Car Battery Voltage Without Using MultimeterIt is actually not possible to get an accurate result without using a multimeter to check your car battery’s voltage. However, there’s still a way to check it without using the tool. This tip will come in handy when you’re about to head out for a trip or if you need to do a quick check to see if it’s still performing well. First, turn the car off and turn on your headlights. Start the car while making sure that the brake is on. Second, watch the headlights’ brightness attentively and if they don’t reach a stable brightness while you start the engine, your car battery might not have enough charge to function well. If this happens, it’s best to find the nearest service centre to get the car battery checked thoroughly.

It only needs to drop down to around 10.5 volts to be considered fully discharged. If it drops down below that, the battery will become damaged due to excessive sulfation.
At what voltage is a 12v battery dead?Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means it's about 50% charged.
Is 12.2 volts enough to start a car?At 12.4 volts the battery is considered 75% charged and can still ignite your engine. When the battery voltage lowers to 12.2 volts without the engine running, it is considered a bad battery that may start your engine but is no longer capable of holding a charge.
Is 11.6 low for a car battery?If your battery drops to a voltage of 11.9V or less, you're going to notice a serious drop-off in performance. Once it goes down to 11.6V, the battery is almost completely discharged.
