How to know if your CMOS battery is failing

Ultimately, the specific voltage for any given CMOS battery will depend on its design and quality.īut regardless of specific details, it is clear that this small but vital component plays an integral role in ensuring that our computers continue to run smoothly no matter what. Other factors that impact CMOS battery voltage include current draw, temperature, and output capacity. In addition, the low voltage helps to ensure that the battery has a long life span, making it an important component of any computer system. This low voltage is necessary in order to power the memory and keep it protected during times when the computer is in standby or hibernate mode. The voltage of a CMOS battery, also known as a backup battery, is typically 3 volts. Therefore, it is important to be aware of this risk when working with electronic devices or handing over your old devices for recycling or repair. Moreover, if the device is not restarted within a certain period of time after the battery is removed, it may become permanently inoperable.ĭepending on the type of device and its programming, the consequences of removing this battery can range from mildly inconvenient to completely disastrous. In addition, any other custom settings that are saved to the battery, such as screen brightness, sound volume levels, and boot-up preferences, may be lost as well. If a CMOS battery is removed from a device, several consequences can be expected.įirst and foremost, the date and time settings of the device will be lost. What will happen if the CMOS battery is removed?

If you want to extend the life of your CMOS battery, it is important to keep your computer equipment clean and free from dust buildup, as this can damage the connections between the computer’s system board and the battery itself. In general, a CMOS battery will last anywhere from 2-10 years, though this will depend on a number of different factors, including how often you use your computer and the type of power settings that you have in place. If you notice any signs of wear or damage to the battery, or if it stops working properly, it is important to replace the battery immediately in order to avoid any negative impact on your computer’s performance. Your CMOS charges when your computer is plugged into its power source. Due to its essential function, CMOS batteries must be maintained and replaced periodically in order to ensure optimal performance from your device.

It is typically located near the CPU or motherboard, in an area where it can be easily accessed by the user. The CMOS chip is a small battery typically used to keep system time and clock settings and other important hardware settings and information stored in the CMOS memory of your computer, as well as what is responsible for allowing you to still use your computer even when it isn’t plugged in.

How to know if your CMOS battery is failingĪ CMOS battery, also known as a real-time clock (RTC), non-volatile RAM (NVRAM), or CMOS RAM is found in both desktop computers and laptop computers, although they are typically only found in laptops.
