How many volts does a computer motherboard battery have?

The button battery on the computer motherboard is a CR2032 model with a voltage of 3V. It is used by the computer system to record time, that is, to maintain the accuracy of the system clock. When the power is insufficient, the time will return to the factory date and Recording the hardware information used to boot is to maintain CMOS BIOS information.

The button battery on the computer motherboard is a CR2032 model with a voltage of 3V.

The computer motherboard button battery is used by the computer system to record time, that is, to maintain the accuracy of the system clock. When the power is insufficient, the time will be returned to the factory. Date, and record the hardware information used to boot, which is to maintain CMOS BIOS information.

Button batteries are also divided into two categories: chemical batteries and physical batteries. The most commonly used battery is chemical battery. They consist of an anode (positive electrode), a cathode (negative electrode) and their electrolyte.

The button battery is made of stainless steel and serves as the positive electrode. The negative electrode is a stainless steel round cover. The positive electrode and the negative electrode are insulated by a sealing ring. The sealing ring is made of nylon. In addition to insulation, the sealing ring also Can prevent electrolyte leakage.

Extended information:

Because the high-voltage cascade battery of button battery is produced by a combination of ordinary carbon batteries. Generally, it is not easy to store for a long time. When purchasing, you should pay attention to the production date and try to use products produced within one year.

Single button battery products sold in domestic and foreign markets should be labeled with mercury content (the labeling method of mercury content in battery products is different from that of domestic environmentally friendly battery manufacturers, with "low mercury", "no mercury" or "mercury" 0", "Mercury is 0" and other methods). When consumers buy batteries, they can judge whether the battery is environmentally friendly by observing the mercury content in the battery.
