| Button battery is known as a small battery which is | | | | for displaying the voltage on the DCV scale. |
| commonly used to power the small electronic devices. | | | | The third step that you should do is to determine the |
| This button battery gets its name because it is round | | | | positive side of your battery by finding side with a "+" |
| and resembles buttons or coins. Many people are | | | | that marked on it. After that, you need to touch the |
| actually not really familiar with this quite new type of | | | | positive probe of multimeter (red) anywhere on this |
| battery. When you are having electronic device which | | | | side. |
| stops working, it may be caused by a simple matter of | | | | The fourth step is to touch negative probe of |
| the dead or dying button battery. At this time, this | | | | multimeter (black) to the negative side of your battery. |

| method for the button battery that will help you to | | | | the positive side. |
| check its condition. | | | | The last step is to take a note of the voltage that is |
| As the first step, you should remove the battery from | | | | displayed on the multimeter. If you find that the voltage |
| your device and then you need to inspect it for | | | | is about 10 percent less than the marked voltage on |
| determining the battery voltage. The voltage is usually | | | | battery, you need to replace it. For instance, the 1.5 |
| marked on the battery. It is known that most of the | | | | battery must show the voltage of at least 1.35 volts, |
| button batteries are made between 1.35 and 3 volts. | | | | while the 3 volts battery must show the voltage of at |
| As the second step, you need to set the multimeter | | | | least 2.7 volts. |
