Duracell Battery Temperature Indicator
Surely every one of you knows that most Duracell batteries have a built-in charge indicator. If you have such batteries and they are completely discharged, but don’t discard them, as a visual indicator of temperature can be made from the indicator of such a battery.Everything is very simple. When you press the button, the contacts of the metal foil are closed under the braid.An electric current begins to flow through this foil, which causes the foil strip to heat across its surface. On the top there is a strip with divisions of different colors. These are cells with a thermal paint that changes color depending on temperature. Each cell has its own paint, which reacts to different parts of the temperature. The red area is the most sensitive, and the last green is not the most sensitive and requires a maximum temperature. As a result, when the strip of foil heats up,depending on the temperature of its heating, different parts of the indicator are illuminated. As a result, an approximate battery charge level is determined. In fact, a strip with thermal paint is a ready-made temperature indicator. Using this indicator, you can visually monitor the temperature of something, such as a kettle, mugs, cans, etc.Bend down. So it looks inside.Cut off the braid.The cut indicator looks like this.The indicator showsthat the soldering iron began to warm up
How does the battery charge indicator work?
Remove the indicatorIn order to reach the indicator, take a clerical knife. And cut the line at the side near the indicator.
Temperature indicator testTo test the temperature indicator, I will put it on the cold soldering iron and plug it into the network.
Practical applicationFor control, we glue the indicator on a glass jar.div> >
