But when we connect the resistor, we can see that the voltage has dropped to 0.863 volts. When we take a measurement with no load, it oddly has a reading of exactly 1.5 volts. ![]() However, this battery is also rated at 1.5 volts. ![]() With the resistor connected, we take a reading of 1.547 volts, so this battery is still good. For example, this battery has a rated voltage of 1.5 volts. If the battery is still good, then the voltage level will only drop slightly. This way current will flow through the resistor and we can take a voltage reading as this occurs. In this case, I’ve just used some crocodile clips to connect the resistor between the probes like this. We connect the resistor between our two probes. Ohms, but it doesn’t have to be exactly this value, though. To fully test the battery, we need to test it under a load condition to check whether it’s still useful. However, sometimes we could still get a voltage of around1.5 volts. This one, for example, reads 1.07 volts, so it’s completely dead. When the battery is dead or dying, we get a lower voltage. The two values are close, but usually not the same. You can see that this battery is rated at 1.5 volts, but when we test it, we get 1.593 volts. To measure the voltage, we simply need to select the DC function on our multimeter, and then we connect the red lead to the positive terminal and the black lead to the negative. ![]() Scroll to the bottom to watch the YouTube tutorial.
