How can you tell if a battery still has power?
There are a couple of ways to look at a battery and give it a "test" to see how good it is. One is to measure the voltage, which is a static test. This in not the most definitive way to check out a battery, but it can give some indication as to how much energy is left in the battery. The "proper" voltage that a battery has will creep down as it is used, and then fall off quite dramatically near the end of its usefulness. For example, if you see a battery that should have 1.5 volts across it and it reads 1.1 volts, most of the energy in the battery has been drawn off. The second way to test a battery is the load test, which is a dynamic (and more "real") test. If we use a battery tester, which is simply a resistive load with a "scale" on it, we can get a better idea of how much energy remains in the battery. The little units basically look at how much the voltage "sags" or "drops" when we apply a load. The scale gives some indication as to the remaining energy reserve based on that test. The more the voltage drops when the battery is loaded and asked to deliver current, the less energy that remains in it.
How can you test non-rechargeable D cell batteries for voltage?
Put a test meter on the end of the D-cell battery
What is a battery discharge tester?
It is a meter with a high wattage resistor connected parallel with the meter that drains power from the battery while it is measuring the voltage it is used to test the condition of the battery if the condition is good there will not be a large voltage drop while testing the battery
Why does a battery not work even though it has a volt reading?
A battery may have a small voltage potential but not the "CAPACITY" to deliver amperage. For instance if you were to measure the voltage at the battery terminals with a Volt/Ohm meter (VOM), you would get a reading of say 12+ volts. As soon as you turn something on such as a headlight or heater motor, the voltage drops down or goes to 0 volts, you would have a battery that is bad or under capacity. It also could be caused by a "BAD CONNECTION" such as a loose battery post clamp. It is critical that when you test a battery, you test it at the battery posts themselves without the cables attached to rule out a bad connection. This is done with a battery load tester. As many people do not have the equipment to test a battery, batteries can be tested at many automotive parts retail outlets across the country for a free charge.
How do you test a relay with a 9v battery?
You can test a relay with and without a 9 volt battery. If you apply 9 volts to it and it's sufficient to turn on the relay, the NO switch will close and then have continuity with common. If you don't apply voltage, the NO switch will be open and not have continuity with common. You can use these continuity and resistance checks to test a relay to see if it works.
