  • Due to the way the battery discharges, it is important to let the car sit for at least one hour, or overnight, before you use the multimeter to test your car battery. If the car is running when the battery is tested with a multimeter, the charge from the powered alternator, which is the component that produces electricity and charges the battery, will affect the ‘true’ reading of the multimeter. If the car has recently been running, the battery is likely to produce a higher misleading number on the multimeter, thus is inaccurate. - Source: Internet
  • There will be a need for a second person in order to start the ignition in order to get this reading, so a second person will be required. In the immediate aftermath of turning the ignition on, the voltage reading should fall for a brief moment, but it should not drop below 10 volts for a long period of time. It is obvious if this value falls below 10 volts that the battery has insufficient turnover strength and is therefore prone to failure if the voltage drops below 10 volts. It is possible that recharging or replacing the battery is required in this particular case. - Source: Internet
  • If your battery is consistently charged at less than 80%, acid stratification can occur. This means that the electrolyte collects at the bottom of the battery, causing the upper half to be acid-poor. Acid stratification reduces the battery’s performance and may cause it to fail. - Source: Internet
  • Cranking the engine tells a bit about your battery. Turning the ignition on till the starter engages is the way to crank an engine. Hold it for another two seconds. Have a helper crank engine, while you check battery’s voltage. - Source: Internet
  • Make note of the voltage reading on your multimeter screen. Different volts would mean different levels of charge. Checkout this reference table before inferring results. - Source: Internet
  • Batteries are most likely found under the hood, near the fender. But there are exceptions. Some car makers tend to place battery in unclear places. Its location could be in the trunk, the backseat or even the wheel well. - Source: Internet
  • If your previous readings meant the battery is sufficiently charged, there is nothing wrong with the battery. If the reading meant otherwise, we have to recharge the battery to check if it holds charge. Battery can be charged either with a portable battery charger or an alternator. - Source: Internet
  • In order to determine the problem with your battery, it is important to perform a proper battery testing procedure. With a dedicated battery tester, you can easily test the health of your car’s battery in a detailed manner. A multimeter could be used, but you would not get the same amount of information about what is going on inside the battery as you would with a multimeter. - Source: Internet
