How do you tell if a battery is or is not working?
You check the voltage under load. Even a bad battery may have good voltage if no current is flowing, so you need an appropriate "test" load.
How do you tell if car battery is dead or can still take a charge?
below its desired voltage
How do you detect the charge level of rechargeable battery .. is there any special circuit to do that?
If you want to know the voltage of any battery you need a volt meter. These can be as cheap as 15- hundreds of dollars. Knowing the voltage still doesn't tell you if a rechargable battery is fully charged or not. a charger with an indicater can tell you that.
How do i tell the voltage of my lawn tractor battery?
You will need a voltmeter. Hook the red cable to the + post and the black cable to the - post and it will show the voltage.
A battery produces voltage using?
battery produces voltage by
What is the lowest voltage for car battery and still be good?
The lowest voltage a battery can drop to during cranking while still starting the car is 9.6v. You can tell a battery's state of charge by the voltage (12.6v is fully charged, 12.0v is low), but the way to tell if a battery is bad is to look at how the voltage changes under load. Most battery testers put a load of half the cold cranking amperage indicated on the battery and look for the voltage to drop below 9.6v, in which case the battery is determined to be bad. Another way to do it at home is to charge the battery at high amperage (can be done by revving the engine slightly and turning off electronics) and, using a voltmeter, look for the voltage to be above 15.5v. This indicates a lower amperage charge than desired and also that the battery should be replaced.
Does higher voltage mean longer battery life?
Yes The larger the battery, the more voltage the battery has.
What microphone uses external voltage supply such as a battery?
Look at the microphone datas, they will tell you, what external voltage you need. Only dynamic microphones like the Shure SM57 need no extra voltage.
How can you tell if there is a bad connection between the battery and the alternator?
Use a vom meter, or battery tester and with the engine running voltage should be approximately 14.5 volts.
Why does your Panasonic phone tell you not to use 1.5v rechargeable batteries instead of their original 1.2v rechargeable battery?
Using standard cells with 1.5v nominal voltage, will take the total battery voltage too high and damage the circuits.
Does a 9 volt battery has more voltage than a d battery?
yes more voltage
What is the voltage source and what is the conductor in a battery?
The battery is the voltage or power source, the wires form the conductor.
