AI Customer ServiceThe complete circuit diagram for the 18650 battery capacity tester is shown below. The explanation of the circuit is as follows-Computational and Display Unit: This circuit is further divided into two parts, first is a low 5V
AI Customer ServiceThe tester has a built-in lithium ion polymer rechargeable battery. Prior to the use of the unit, the battery cable connection behind the battery door needs to be connected and the unit fully charged for no more than 8 hours prior to use. Pressing the key for two seconds will power on or off the tester.
With a voltmeter, checking a battery would be a very simple process. But if you do not have one, there are other ways to go about checking the level of a battery to see whether it is still good or not. Now we will build a circuit which can show whether the voltage that a battery is outputting is above or below a certain level.
And we can adjust this reference voltage level to any voltage we want. So if we want to test a AA battery, which is a battery which contains 1.5V (or a little above) when brand new, we can set the reference voltage to about 1.4V. If the battery's voltage is above this level, then we know that the battery is good.
So now that the voltage comparator is fully explained, the only other components we need are an LED, a current-limiting resistor to keep the LED from burning out, a power source, and the battery which you want to test. We will also need a battery holder so that we can connect to the circuit.
Even though this seems really complicated for just a simple battery tester, it's a really good circuit for a foundation in which we can create any voltage level and see whether a device is outputting a voltage above or below this level, so it can be used as for many other circuits, so it's a good foundation for measuring voltage levels.
So if we want to test a AA battery, which is a battery which contains 1.5V (or a little above) when brand new, we can set the reference voltage to about 1.4V. If the battery's voltage is above this level, then we know that the battery is good. It's at full strength.
