Description

CR2032 CMOS Battery

One of the important aspects of a computer is storage. People are very much concerned about having a place to store information, and that any piece of fact is stored even in cases of sudden loss of power supply or computer errors. And that is why there is a CMOS RAM in a PC motherboard. It is a small memory, now referred to as non-volatile BIOS memory that stores BIOS (basic input/output settings). The CMOS is powered by a battery. Even when a personal computer is powered by electricity, the memory is powered by battery in case real power goes off.

A common battery used for this purpose is the cr2032 CMOS battery, a 3-volt battery with a chemical composition of lithium magnesium dioxide. It is lightweight, round, and silver in color. It is commonly known by many as the watch battery. This cr2032 CMOS battery generally gives power to the memory and the personal computer’s real-time clock. It lasts about 2-5 years depending on such factors: temperature, the type of motherboard it gives power to, and the period of time that the system is put off. The longer the power-off time, the shorter the cell life will be. And even though the cr2032 battery has an operational temperature range of -20 to + 70 degrees Celsius, it may still have a shorter life service if exposed to higher temperatures and ambient heat. When a cell dies out, it is then replaced; and the system time and BIOS settings are usually put back to default values. A power supply master switch may be left on in order to keep the battery’s life longer. This will supply standby power and keep the CMOS memory energised even when the motherboard is idle or switched off.

The cr2032 CMOS battery can easily be replaced if it eventually loses its charges and the computer starts to receive CMOS read error and other problems. To avoid the BIOS settings from reverting to default, write down all system settings. After which, locate the battery on the motherboard. Battery information must be obtained so that the cr2032 CMOS battery may be replaced with the exact same one, or with an equivalent. Voltage, chemistry, wiring and packaging are to be considered, especially if the PC is not up to date. Remove the battery while the computer is off. This may be done with bare fingers. Then the new battery should be replaced. The final step is to enter the CMOS values. This is why information about the system settings is recorded beforehand, so that they may be entered back to the CMOS. Save settings before exiting and it’s done.
