As you know, the life of the batteries is different and when one fails, it entails the termination of the entire electronic device, regardless of whether the working batteries are left in it, or not. Therefore, it is very important to be able to determine the charge capacity in order to understand whether it is possible to use a seeded battery in equipment with lower power consumption or it is time to dispose of it. How to check the battery - in this article.
How to check the battery performance?
- To do this, you need a device such as a multimeter. Connect the test leads of the tester to the battery , observing the polarity, that is, plus to plus, and minus - to minus. Set the work switch to "Amperes - DC". Volta's position for checking the batteries is not used.
- Those who are interested in how to check the batteries at home on voltage, it is necessary to include a pull-up resistor. Significant input resistance can be ensured by the inclusion of the tester in the voltage measurement mode. With a minimum load, the battery will display almost full, or absolutely full voltage. In the event that a faulty battery is installed in any device, the voltage will immediately go down.
- For those who are interested in how to check whether the battery is working, it is necessary to switch the toggle switch responsible for the job to DC mode to the maximum limit, that is, to install opposite the inscription on the device "DC voltage check mode". Touch the terminals of the battery terminals for literally 1-2 seconds, having recorded the meter readings. It is not necessary to hold any longer because of the danger of short circuit, which can negatively affect the functioning of the power supply. Remove the current reading from the device to determine the suitability of the battery.
- Asking how to check the battery capacity, conclusions about its performance can be drawn from the following data: the current value within 4-6 amperes is typical for a new power source, the current is within the range of 3 to 4 Amps will suffice to provide power to portable equipment, although and not for long. If the tester outputs a result of 1.3 to 2.8 amperes, the battery can be inserted into equipment with a low current consumption, for example, a remote control.
If, along with new batteries, there are also those with a current value of 0.7 to 1.1 Amp, you should not rush to throw them away. Such a seeded power source can be installed in the device together with a new one and ensure its high-quality work.
