56 Shocking Facts About How To Use A Voltage Meter To Check Car Battery | Battery Cranking Test

• As we’ve discussed the resting voltage should ideally be no lower than 12.6V. Bear in mind that when a battery goes down to 12.2V it’s actually only 50% charged, and below 12V it’s classed as discharged! - Source: Internet
• Performing a DIY test on your car sounds intimidating, especially if you have no technical expertise. Nonetheless, performing a load test on the car battery is quite straightforward. Here are the steps to follow: - Source: Internet
• A battery that shows low voltage may still be good if it is fully charged. You need to check if the battery will hold a charge to determine if it is good or bad. To determine if the battery is defective, follow the next section’s procedure to perform a battery load test. - Source: Internet
• To use a multimeter, two “probe” wires are inserted into the base unit, then attached to something with an electrical charge (like your battery!); the dial usually tells the multimeter what sort of measurements to take. The dial may have a multitude of settings but for testing your car battery we’ll only be looking for one: DC (or “direct current”), set to 20 volts. The DC side of the multimeter dial will be designated by a “V–” symbol (there will be three dots underneath the straight line as well); “V~~” (with tildes) is AC (alternating current) and is the wrong setting for this test. - Source: Internet
• Connect the test probes to your cell, with the black wire meeting the negative. The red wire should meet the positive and then check its display. If you get a number which is higher than 7 for a 9-volt battery, it is still usable, and the cell will last for some more time. - Source: Internet
• If your measurement is more than the minimum value, which is usually 12 volts, the battery has a good charge and will last. However, this is not the only way to judge if the battery is in perfect condition. One also needs to check if the car is able to draw power successfully. - Source: Internet
• Firstly take a multimeter and place it on the table. Also, bring in the battery you want to test. We will explain the process with a 9-volt battery for this guide. To correctly measure the voltage, turn your switch dial to DC voltage measurement. - Source: Internet
• Learn how to test a battery. Learn how to test a battery. How to use a multimeter to test a battery. What happens to the battery voltage under load. How to tell if the battery needs replacing. - Source: Internet
• As the main load on a conventional starter battery is due to the starting process and after charging by the generator there is no further discharge, the cold start current is decisive in this case. Due to aging and wear the capacity of the battery to deliver high currents gradually decreases. In addition, the lower the charge (determined by measuring the open circuit voltage), the lower the possible current which can be deliverd during the starting process. - Source: Internet
• This needs to be done because a battery generates DC power, and this means you will need to measure it with the same unit. So it is essential to know the maximum voltage of the battery. Set the dial to 20 volts, which is the maximum range. - Source: Internet
• Most car batteries are located in the hood of the car, near the engine block, though some models of vehicle (and many European cars) have the battery located in the trunk, underneath the floorboard. Once the battery has been located it may have an additional plastic hood on the top that can be removed to access the battery underneath.\ - Source: Internet
• So with the engine running (and being mindful about moving parts) conduct the same battery test as above with your multimeter. A healthy charging system should give a reading of between 13.8V and 14.4V at regular idle speed. - Source: Internet
• Enter the stated cold start current for the battery into the device, including the measurement method which is used. Common standards are DIN, EN, IEC, JIS and SAE. Details of the testing standard can be found after the details of the cold start current on the battery label. - Source: Internet
• Any automotive repair shop or even some auto parts stores can load test a battery for you. It is not accurate to assume that the battery itself is bad because a battery is discharged. To determine whether the battery is good, charge up the battery and perform a load test. - Source: Internet
• One thing to bear in mind is that all modern cars experience ‘parasitic loss’ where something electrical drains the battery even with the engine turned off. Even with all the lights and engine turned off, the digital clock, computer, and several other systems use some power. If you suspect this is killing your battery during storage, you can either disconnect the battery, or remove the battery from the car entirely. - Source: Internet
• However, we strongly recommend that you practice on different cells to get the hang of it. Maybe consider practicing with the different batteries used for household items like the remote, video game, torch, and even a battery from a lamp. The more you play around with different cells, the better you understand various charge positions. - Source: Internet
• The process is the same as above. You would need to connect the probes to the battery terminals. Then proceed to check the reading on the multimeter display. - Source: Internet
• If you get less than 12.6 volts, disconnect the battery and fully charge it with a battery charger. Then test after an overnight rest. If the battery holds a charge when it’s not connected to the car – something is draining the battery far faster than the computer memory and digital clock. - Source: Internet
• Today, we are here to tell you how to use one correctly. From TV and AC remotes to battery operated lights, there are a lot of products that need proper functioning cells to run. Even our cars cannot run without cells. - Source: Internet
• If the terminals are heavily corroded the battery may need to be removed and cleaned before it can be properly tested – Corrosion can give off false or otherwise imprecise readings. Remove the battery according to manufacturer’s instructions and clean the corroded bits with terminal cleaner and a terminal-cleaning brush. If it comes to this point, taking it into a shop for this step might be your safest option. - Source: Internet
• Testing your car battery from the comfort of your home is quite simple, inexpensive, and allows you to learn something new. Next time you suspect that the battery is malfunctioning, there’s no need to call a technician. Instead, choose any of these tests and get down to work. - Source: Internet
• So we take a resistor of around 100. Ohms, but it doesn’t have to be exactly this value, though. We connect the resistor between our two probes. In this case, I’ve just used some crocodile clips to connect the resistor between the probes like this. This way current will flow through the resistor and we can take a voltage reading as this occurs. - Source: Internet
• So here we will talk about how to get accurate measurements of the current of a battery. The average amperage of the battery would be somewhere around 100 mAh. So before measuring, turn the dial to DC function and keep it at 200 mAh. - Source: Internet
• If it fluctuates somewhere around 100 mAh, it is working alright and will run any small device efficiently. We tested it on our TV remote control battery, and we got 98.3 on our display, which was a satisfactory result. - Source: Internet
• The ideal situation would be if the reading drops to 10V but then returns to a higher value around 12 V. If the reading stays constant after the initial value drop, then you would know your battery is in perfect condition. The engine needs to be running throughout the process. - Source: Internet
• During a load test, car batteries must supply at least 9.5 volts during engine cranking. The battery needs to be fully charged to perform a load test accurately. Checking the voltage can be misleading because the battery may test well based on voltage but can not hold a load. - Source: Internet
• When using a load tester, a load will get applied to your car battery, as the tester determines the battery voltage. In case the voltage dips below 9.6V, it means that the battery is bad and needs replacing. Alternatively, you can use an electronic tester to determine the capacity of your car battery. In this case, the tester will send frequency waves through the battery to establish the condition of its cells. - Source: Internet
• The battery ratings vary a lot from car to car, but choosing 15-20 Volt is good enough. We selected 20V before proceeding to measure the level. Allow us to give you a piece of advice here – you should keep the headlights on for a few minutes before checking the battery. This would drain away any remaining charge. - Source: Internet
• But if you are confused about buying a multimeter because you do not know how to use it, here’s a guide that will provide the details. Read on to learn how to measure voltage levels for different types of cells. Also, we will tell you how to understand when to buy new batteries because they are running out of juice. - Source: Internet
• To connect the testing device to a battery which is located in the trunk or the passenger compartment, the battery terminals there and not the starting aid contacts in the engine compartment must be used, as the resistance of the cable which is installed in the vehicle would affect the measurement.

• Get any 12-volt Trickle Charger. Connect the red positive clamp to the battery positive terminal. Connect the negative clamp to the negative battery terminal. - Source: Internet
• Before you replace that expensive battery, it is good to perform a battery check to ensure the battery is bad. Otherwise, you may be replacing a good battery for no reason. This article covers how to test a car battery using a Digital Multimeter and a Battery Analyzer. - Source: Internet
• Just because the battery is reading over 12.6 volts doesn’t always mean the battery is good. The battery may read over 12.4 volts yet not output enough Cold Cranking Amps (CCA) to start the car. In the next section, you will learn how to perform a battery load test. - Source: Internet
• You can also test your car battery capacity from home using a hydrometer. The electrolyte gravity test helps you establish whether the battery is undercharged, fully charged, or even faulty. It’s recommended to use a hydrometer that has an in-built thermometer. - Source: Internet
• The battery is your car’s lifeline since it powers all electrical components. If the battery works below its capacity, the vehicle’s performance will be significantly affected. The car won’t even start if the battery malfunctions. Rather than waiting for your car battery to start showing signs of weakness, you should test it regularly alongside other components of the car’s electrical system. Here’s how to test your car battery like a pro. - Source: Internet
• On the other hand, if it is a dead battery, it would show results below 1. If that is the case, it is time to buy a new one. Mostly, it is enough to just check the voltage to get a clear understanding of the battery. - Source: Internet
• If the car’s headlights noticeably dim as the engine starts, the battery has failed the load test. A car battery working at full capacity should be able to hold enough charge for 10-15 minutes until the engine starts. If you notice that your battery is struggling, consider changing it before it fails you in the middle of nowhere. - Source: Internet
• Your probe wires should be colored red and black, with corresponding red & black ports on the multimeter base for them to fit into. If multiple ports exist your black probe should go into the slot labeled “COM”, while your red connector should go into a port labeled “volts/homs/milliamps”. If a port labeled “10A” is present do not use it for testing your car battery; this could damage your multimeter. - Source: Internet
• To test each cell, you need a hydrometer-style battery tester that measures the specific gravity of the battery acid. Based on the number of balls floating, you can tell whether the cell is dead or not. However knowing a cell is dead is of no more use to you than knowing that the battery won’t hold a 12.6 volt charge, because you can’t fix it. So, a test of the resting voltage is just as effective a diagnosis. - Source: Internet
• A digital variant is easier to use and will always be the preferred choice, but again, it is not the only way to get the job done. There are a number of multimeters available in the market today that simulate a load to test the battery. These devices can be great additions to your tool collection. - Source: Internet
• In short, you will need to set the multimeter to the 20-volt DC setting. Next, turn off the ignition and lights. Connect the red cable to the battery’s positive (+) terminal and the black cable to the battery’s negative (-) terminal. - Source: Internet
• #2 - We already know that the voltage of the battery is 9V maximum, so we will point the dial to 20V (as shown) i.e. the higher range - Source: Internet
• First the battery needs to be in a resting state, so leave the car overnight. This allows the alternators given charge to the battery from driving around to drop to it’s ‘resting’ voltage, which is the measurement you want to take. The resting charge is what starts the engine on freezing mornings don’t forget! - Source: Internet
• #1 - In Part 1, we will measure the voltage of the battery. To do this, use the switch dial to select DC voltage measurement. Since battery generates DC power, we will measure DC voltage. - Source: Internet
• Connect the battery tester to the battery terminals to determine the state of charge and the internal resistance. In principle: Connect the red cable to the positive terminal and the black cable to the negative terminal. The sequence for connection and disconnection does not matter. - Source: Internet
• When the alternator charges, the battery is not a healthy battery; a fast charge would be the case. Use the slow charging method if you want to charge your battery to 100% properly. A trickle charger takes longer but brings the battery to a fully charged state. - Source: Internet
• In other words, an electronic tester measures the conductance of the battery cell. Some but not all battery analyzers measure the battery’s Cold Cranking Amps (CCA), such as the Foxwell BT-705 Battery Analyzer. By measuring the CCA capacity of the battery, you can determine the battery’s remaining life. - Source: Internet
• If your car hasn’t been starting you can also perform a crank test: Have a friend or family member crank the car for you while the terminals are attached. If your reading dips below 10.0 volts (or more than 2 volts less than your initial reading) this is a sign that your battery may not be producing enough current to handle the starter motor. - Source: Internet
• #4 - The display should read a value that is just short of 9V. Since this battery has been in use for some time, it shows 8.74V, which is still enough for it to supply current to the load. - Source: Internet
• Going through best car battery testers: reviews and buying guides is the first thing that most car owners do when they realize that their batteries are underperforming. Well, this is a step in the right direction since the car battery guides and reviews help you figure out whether your car battery is good or bad. Besides, most dealerships use load testers to assess the capacity of car batteries. - Source: Internet
• According to the latest studies by the German Automobile Club ADAC, in 2017 about 40% of breakdowns were due to the battery. The reasons for this include the increased electrification of vehicles. These days, greater demands are made on the battery – up to 150 electrical consumers and the automatic start-stop system in modern cars require sufficient power. A regular battery check by a specialist workshop is therefore advisable in order to detect an imminent battery failure before a final breakdown occurs. - Source: Internet
• Most hydrometers that you’ll come across are self-adjusting. In contrast, others feature a conversion table that allows you to adjust readings while performing the electrolyte gravity test at various ambient temperatures. For safety purposes, you should wear acid-resistant goggles and gloves when performing this test. For the best results, you should follow these steps: - Source: Internet
• Set the battery tester to the correct battery type: Starter battery, gel battery, EFB or AGM battery. The device uses a different test algorithm for each battery type, so that an incorrect setting would produce an incorrect measurement value. In addition, for some test devices it is important to know whether the test is being made on a battery installed in the vehicle, or whether it is outside of the vehicle. - Source: Internet
• Once the terminals have been exposed take caution, as the battery is very much “live” and can cause shock and injury if touched. Of particular note: Never let an object bridge the two terminals, as this can lead to a dead battery at best and a literal explosion at worst. Work with care and attentiveness, and make sure to keep metal tools and jewelry away from the battery terminals. - Source: Internet
• Batteries are commonly located in the engine bay to one side of the engine. If the battery is not immediately obvious when you open the hood, consult the owner’s manual. In modern cars, the battery will often have a plastic cover which will unclip, hinge up, or occasionally require removing with a few bolts or screws. There may also be a red cover over the positive (+) terminal that will lift off or snap open too. Once the battery is exposed be extremely careful that nothing metal touches the terminals and causes a short, so don’t set wrenches or other tools on top of the battery. - Source: Internet
