Batteries for automobiles should measure at least 12.60 volts when fully charged. It should measure between 13.7 and 14.7 volts when the engine is running.
A multimeter is preferred when we like to test our auto battery. What if there isn’t a multimeter available, and how could we perform the test without a multimeter?
There is a way out! Start your car and turn on the headlights if you do not have a multimeter to find out the voltage of your battery. The dim lights indicate that the batteries are low or not charging and the alternator is not generating enough charge. When you rev the engine, you’ll notice the lights get brighter, which means that the alternator produces electricity, but maybe not enough to keep the battery charged at idle. Your charging system is probably working properly if the lights are of average brightness and do not change intensity as the engine is revved. You should check the battery for a leak, or if something on the vehicle is discharging it. If your battery has been malfunctioning and the headlight test checks out okay, you need to determine whether the battery is holding a charge.
A multimeter would be helpful or check the headlights, but neither would be the most convenient option. What about there is one suitable option to do the test?
