When it comes to building or upgrading a computer, one of the most overlooked components is the motherboard battery. Also known as the CMOS battery, this small battery plays a crucial role in powering the motherboard’s clock and configuration settings. With so many options available in the market, choosing the right battery for your motherboard can be a daunting task. In this article, we will explore the different types of motherboard batteries, their characteristics, and factors to consider when making a purchase.
Understanding Motherboard Batteries
Before we dive into the different types of motherboard batteries, it’s essential to understand their purpose and how they work. The motherboard battery is responsible for powering the following components:
- Real-time clock (RTC): This is the clock that keeps track of the time and date.
- CMOS settings: These are the configuration settings stored in the motherboard’s CMOS (Complementary Metal-Oxide-Semiconductor) memory.
- BIOS settings: These are the settings stored in the motherboard’s BIOS (Basic Input/Output System) memory.
The motherboard battery is usually a small, round battery with a voltage rating of 3V. It’s typically located on the motherboard, near the CPU socket.
Types Of Motherboard Batteries
There are several types of motherboard batteries available in the market, each with its own characteristics and advantages. Here are some of the most common types:
- CR2032 Battery: This is the most common type of motherboard battery. It’s a 3V lithium battery with a capacity of 220mAh. CR2032 batteries are widely available and relatively inexpensive.
- CR2016 Battery: This is another popular type of motherboard battery. It’s also a 3V lithium battery, but with a lower capacity of 90mAh. CR2016 batteries are smaller than CR2032 batteries and are often used in laptops and other portable devices.
- BR2032 Battery: This is a 3V lithium battery with a capacity of 180mAh. BR2032 batteries are similar to CR2032 batteries but have a slightly lower capacity.

By following the tips and precautions outlined in this article, you can replace your motherboard battery with confidence and ensure your computer continues to run smoothly.
What Are The Key Factors To Consider When Choosing A Battery For My Motherboard?
When choosing a battery for your motherboard, there are several key factors to consider. The first factor is the type of battery required by your motherboard. Most modern motherboards use a CR2032 lithium coin cell battery, but some older models may use a different type. It’s essential to check your motherboard manual or manufacturer’s website to determine the correct battery type.
Another crucial factor is the battery’s voltage and capacity. The voltage should match the motherboard’s requirements, usually 3V for CR2032 batteries. The capacity, measured in milliampere-hours (mAh), should also be considered. A higher capacity battery will generally last longer, but it’s essential to check the motherboard’s specifications to ensure compatibility.
How Do I Determine The Correct Battery Size For My Motherboard?
To determine the correct battery size for your motherboard, you should check the motherboard manual or manufacturer’s website. The manual should provide information on the recommended battery type and size. If you no longer have the manual, you can check the motherboard’s packaging or the manufacturer’s website for specifications.
Alternatively, you can visually inspect the battery holder on the motherboard to determine the correct size. The battery holder should have markings or labels indicating the recommended battery type and size. You can also measure the battery holder to determine the correct size, but it’s essential to double-check the measurements to ensure accuracy.
What Is The Difference Between A CR2032 And A CR2016 Battery?
A CR2032 and a CR2016 battery are both lithium coin cell batteries, but they differ in size and capacity. A CR2032 battery is 20mm in diameter and 3.2mm in height, while a CR2016 battery is 20mm in diameter and 1.6mm in height. The CR2032 battery has a higher capacity, typically 220-240mAh, compared to the CR2016 battery, which has a capacity of around 90-100mAh.
The choice between a CR2032 and a CR2016 battery depends on the motherboard’s requirements. If your motherboard requires a CR2032 battery, using a CR2016 battery may not provide sufficient power, leading to issues with the motherboard’s clock and settings. It’s essential to check the motherboard manual or manufacturer’s website to determine the correct battery type.
Can I Use A Rechargeable Battery In My Motherboard?
While it’s technically possible to use a rechargeable battery in your motherboard, it’s not recommended. Most motherboards are designed to work with disposable lithium coin cell batteries, and using a rechargeable battery may cause issues. Rechargeable batteries have a different chemistry and voltage curve than disposable batteries, which can affect the motherboard’s performance.
Additionally, rechargeable batteries may not provide the same level of reliability and consistency as disposable batteries. Motherboards often have specific requirements for battery voltage and capacity, and rechargeable batteries may not meet these requirements. It’s best to stick with disposable lithium coin cell batteries to ensure reliable performance and avoid potential issues.
How Long Does A Motherboard Battery Typically Last?
The lifespan of a motherboard battery depends on various factors, including the battery type, capacity, and usage. On average, a CR2032 battery can last for around 2-5 years, depending on the motherboard’s power consumption and usage patterns. If the motherboard is used frequently, the battery may drain faster, while infrequent use can prolong the battery life.
It’s essential to monitor the motherboard’s battery life and replace the battery when necessary. A dead battery can cause issues with the motherboard’s clock and settings, leading to problems with the system’s overall performance. Regularly checking the battery voltage and replacing the battery when necessary can help prevent these issues.
Can I Replace The Motherboard Battery Myself, Or Do I Need A Professional?
Replacing the motherboard battery is a relatively simple process that can be done yourself. However, if you’re not comfortable with DIY repairs or don’t have experience working with electronics, it’s recommended to seek the help of a professional. The process typically involves locating the battery holder, removing the old battery, and installing the new one.
Before attempting to replace the battery, make sure to ground yourself to prevent static electricity damage to the motherboard. It’s also essential to handle the battery and motherboard components with care to avoid damage. If you’re unsure or uncomfortable with the process, it’s best to consult a professional to avoid any potential risks or damage to the motherboard.
What Are The Consequences Of Using A Low-quality Or Counterfeit Battery In My Motherboard?
Using a low-quality or counterfeit battery in your motherboard can have serious consequences. Low-quality batteries may not meet the motherboard’s specifications, leading to issues with the system’s performance and reliability. Counterfeit batteries can be even more problematic, as they may contain toxic materials or have a higher risk of leakage or explosion.
Using a low-quality or counterfeit battery can also void the motherboard’s warranty and cause damage to the system’s components. In extreme cases, a faulty battery can cause a fire or electrical shock, posing a risk to the user’s safety. It’s essential to use high-quality batteries from reputable manufacturers to ensure reliable performance and prevent potential risks.
