How do I check the batteries?

Everyone probably has a couple of batteries at home. About how to test the battery with a tester, our article will tell.

1. First, you need to attach thetester to the selected battery. Connections should be parallel: plus to plus, minus to minus. Now you need to install a tester switch that is responsible for the type of work in the "Ampere" or "DC" position. It is not necessary to use the "Volts" or "DC voltage" positions for such a measurement.
2. To test the battery by voltage,you must turn on the load resistor. If the tester is turned on in the voltage measurement position, you will see a strong input resistance. In this case, the battery (which is virtually unloaded) will display almost full voltage, for example, 1.5 Volts. In the case when the battery is idle, then, when it is installed in any device, the voltage will go to a decline.
3. Now you need to set the switch toTester, responsible for the type of work in the position of "Ampere" or "DC" to the maximum possible limit. In the multimeter, this mode is called "DC voltage test". Next, you need to close the battery for a split second to have time to record the readings of your device. Keep it for a long time is not necessary, because it will lead to a short circuit and can spoil the battery. Now you need to remove the current reading from your device to determine the suitability of the battery. Here's how to check the batteries.
4. Here are the conclusions about the performance of the selectedbatteries that you can do after measuring its voltage: the current of the batteries at 12 volts should be at least 2.5 Amperes (cheap finger batteries will show the result from 2 to 2.5 Amperes, and batteries that are more expensive will be shown from 4 to 4.5 amperes).
5. If you see that during the measurement the readingsdo not exceed 1 Amp, do not immediately throw out the batteries, because they can be used, for example, in the remote control of the TV or the player. Also it is necessary to remember that the voltage of a normal battery is 1.5 Volts, and the battery is 1.2 Volts.

Now you know how to check the battery charge!
