This article will discuss how to check a battery's capacity with a multimeter. This is necessary to determine its functionality. The method presented in this article is the simplest and easiest to date!
A step-by-step guide to checking battery capacity with a multimeter
Take a regular tester like this one:
Arrange the probes as shown in the figure below. Also, set the switch to the 10 A position. This is located in the right column of the multimeter.
Now that everything is ready, begin checking the battery capacity. To do this, touch the red probe to the positive terminal of the battery. Touch the black probe to the negative terminal. The contact should last for 3 to 10 seconds. Otherwise, the battery may become damaged or discharge excessively. This procedure essentially shorts out the battery.
As a result of such actions you will be able to find out battery capacityUsing a multimeter. The capacitance is checked on a phone in exactly the same way!
If the battery shows a reading of less than 0.2 amps, it's no longer usable and should be replaced. The screenshot shows the readings of a new power supply. They are 1.74 amps. This is enough to light a small incandescent lamp, turn a toy motor, or operate some other device. For example, a TV remote control would require two similar batteries. A clock and a small radio will also work.
Only small batteries can be measured in this way!
