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. How to tell if the battery needs replacing. ![]() What happens to the battery voltage under load. How to use a multimeter to test a battery. If you experience battery problems but you’re between scheduled maintenance checks, please don’t hesitate to have your vehicle checked.Learn how to test a battery. No manual? No problem! Jiffy Lube ® technicians can access your vehicle’s maintenance schedule and the recommended procedures. The schedule for your specific vehicle outlined in your owner's manual. Typically, it's recommended that the battery be inspected at least every 6 months/6,000 miles. Proper maintenance can help your battery keep working as designed. The higher the CCA, the greater the starting power. WHAT IS CCA? CCA stands for cold cranking amps, and refers to the number of amps a 12-volt battery can deliver at 0✯ for 30 seconds while maintaining a voltage of 7.2 volts or more. The typical battery amperage ranges from 450 to 750 CCA. Simply put: a highly-optioned vehicle is going to have a higher amperage battery. The amperage rating is going to differ based on the number of options your vehicle has. WHAT IS AMPERAGE? Amperage, or amps, is a way to describe car battery current. Now that we’ve looked at how many volts in a car battery and how the battery works, we’re ready to move on to amperage. These three steps repeat, over and over, powering your engine as the electrical energy is again converted to mechanical energy and the alternator recharges the battery to supply additional current. ![]()
