How to Test Your Car's 12V Battery: My Personal Experience & Thought

    ANCEL battery tester BST600

    I recently had the chance to test my car's 12V battery using the ANCEL BST600 battery tester. Today, I'll share my experience and thoughts on the process of testing a car battery and how to use the ANCEL BST600. Additionally, I'll dive into some detailed information about car batteries, sharing my feelings and thoughts based on my rich understanding of them. So, if you're a car enthusiast like me or just looking to maintain your vehicle better, stick around!

    My Experience with ANCEL BST600

    The Setup

    I drive a BMW, and like many car owners, I occasionally worry about the health of my car's battery. So, I decided to try out the ANCEL BST600. This handy device offers advanced testing technology and is designed to measure both 12V and 24V battery systems.

    Connecting the Tester

    First things first, I made sure my car was turned off, and I waited about 15 minutes to ensure that no systems were drawing power from the battery. This is crucial because modern cars can still drain power even after being turned off. Once I was confident, I opened the hood and located the battery.

    Before connecting the tester, I ensured the battery terminals were clean. A small dollop of white Vaseline on the terminals can help prevent corrosion, but be careful as it might affect your measurements.

    Testing the Battery

    I connected the ANCEL BST600's clamps to the battery terminals (red to positive and black to negative). The device powered on, and I selected the type of battery (in my case, a regular lead-acid battery). The BST600's interface is user-friendly and supports multiple languages, which is great if English isn't your first language.

    Analyzing the Results

    The BST600 ran a quick test and displayed the results on its screen. It provided two crucial parameters:

    • State of Charge (SOC): This shows the current charge level of the battery compared to a fully charged state.
    • State of Health (SOH): This indicates the overall health of the battery and how it compares to a new one.

    A healthy battery should show a voltage around 12.6 volts. Anything below 12.0 volts might indicate a problem.

    Printing the Results

    One of the coolest features of the ANCEL BST600 is its built-in printer. After the test, I printed out the results, which is incredibly useful for record-keeping. It's quick, accurate, and convenient.

    Types of Car Batteries

    Car batteries come in various types.

    • Lead-Acid Batteries: These are the most common types found in most vehicles. They are reliable and relatively inexpensive. Lead-acid batteries can be further categorized into flooded and sealed (maintenance-free) types.

    • AGM (Absorbed Glass Mat) Batteries: These are an advanced version of lead-acid batteries. They are more expensive but offer better performance and a longer lifespan. They are commonly found in high-end vehicles.

    • Lithium-Ion Batteries: These are less common in standard vehicles but are gaining popularity due to their lightweight and long-lasting properties. They are mostly used in electric and hybrid cars.

    How Car Batteries Work

    Car batteries provide the necessary electrical power to start the engine and run various electrical components in the vehicle when the engine is off. The battery gets charged by the alternator while the engine is running. 

    • Voltage: A fully charged car battery should read around 12.6 volts. If it drops below 12.0 volts, it might indicate a problem.

    • Cold Cranking Amps (CCA): This measures the battery's ability to start an engine in cold temperatures. The higher the CCA, the better the battery performs in cold conditions.

    • Reserve Capacity (RC): This indicates how long the battery can run the vehicle's essential systems if the alternator fails.

    My Thoughts on Car Batteries

    Understanding your car battery is crucial for maintaining your vehicle's reliability. Regularly testing your battery, especially before long trips or during extreme weather conditions, can save you from unexpected breakdowns. The ANCEL BST600 has made this task much easier for me.

    I find it fascinating how a small device like the ANCEL BST600 can provide such comprehensive insights into a battery's health. It’s a game-changer for DIY enthusiasts and anyone who wants to keep their car in top shape without frequent visits to the mechanic.


    Testing your car's battery is crucial for maintaining its health and ensuring reliable performance. The ANCEL BST600 makes this task easy and efficient. Whether you're a seasoned car enthusiast or just someone who wants to take better care of your vehicle, this battery tester is a great tool to have. I also use  ANCEL auto scan tools, which complements the battery tester by providing a comprehensive overview of the vehicle's diagnostics, ensuring every aspect of my car is in top condition.

    Remember, keeping an eye on your battery's SOC and SOH can save you from unexpected breakdowns and extend the life of your battery. So, give the ANCEL BST600 a try and see for yourself how easy it can be to stay on top of your car's battery health!
