Physical damage can also include damage to the battery’s body, terminal damage and bulging. Leaking fluid – if your battery is showing any sign of leaking fluid it means that the body of the battery is no longer secure as it cannot contain the fluid. Your battery will need replacing if it leaks any fluid. - Source: Internet
• The battery should read 12 volts or something else. If the reading is less than 12 volts, recharge the battery using an appropriate battery charger. If the battery does not charge above a minimum of 12 volts, it is time to buy a new one and change it. - Source: Internet
• An old car battery often needs to be replaced. However, aside from that, several signs will appear before it is entirely dead. Some of the symptoms of a failing battery include: - Source: Internet
• As you can see from the image above the voltage was in the range of the specified voltage. The battery we tested was a 1.5V battery. Anything less than 1V, in this case, would indicate a faulty battery. - Source: Internet
• When testing a battery you should test both the level of voltage and also the level of current that the battery is supplying. Depending on what multimeter you are using to perform the test will depend on the dial test locations and what tests they can perform. We have used an image of a well-known brand of multimeter when testing the battery. - Source: Internet
• Check the label on the battery or circuit breaker for its maximum amperage. Before you connect the multimeter, you’ll need to make sure it’s set for the number of amps flowing through the circuit. Most power supplies have the approximate amp rating printed on their label. - 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
• 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
• 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
• To find out which battery your car uses, you have two options: look at the factory battery label or consult the vehicle manual. The complete data to know the capacity of a battery are 3: The voltage, in volts (V). The amperage, or capacity, which is measured in amps/hour (Ah). - Source: Internet

• – if your battery is showing any sign of leaking fluid it means that the body of the battery is no longer secure as it cannot contain the fluid. Your battery will need replacing if it leaks any fluid. Corrosion – if a battery shows any sign of corrosion on its terminals it can indicate a problem and will need replacing. This can also indicate that the battery has been exposed to water or moisture. - Source: Internet
• Let me say right off that measuring current is a far-less-common application than measuring voltage or resistance. For the most part, either a circuit works or it doesn’t. If it doesn’t, it’s usually because it doesn’t have a voltage supply (which is verified by using the meter to confirm the presence of voltage), it doesn’t have a path for the current to flow (which is verified by using the meter to confirm continuity), or because a part is bad. Thus, it’s rare that you’d need to independently measure how much current is actually flowing unless you’re trying to find the source of a parasitic drain that’s running down the battery. We’ll get to that at the end of this installment. - 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
• Once you have selected the DC voltage mode you may need to set the voltage range of your meter. Some multimeters have an auto-range feature where they will change when connected to different levels of voltage. If your meter does not have this function then you should set it up to test higher than the specified level of voltage for the battery. For example, if you are testing a 6V battery you should set your meter up to test between 0V to 10V DC. - Source: Internet
• The battery has internal damage. You left a light on or a poorly closed door. There is a fault in the alternator. The vehicle consumes more energy than specified when it is turned off or has a current leak. - Source: Internet

• This belief is widespread and incorrect. By adding mineral water inside the battery, we cause the components of the battery to run out. The correct thing is to use demineralized water, for example purified water. - Source: Internet
• With those warnings in mind, let’s do a current measurement. Note that we use the words “current” and “amperage” (the unit of current) interchangeably, but the meter’s dial and sockets aren’t labeled with a “C” for current. They’re labeled with the letter “A” for Amperage. - 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
• 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
• The photo below shows the meter measuring current on a small fan in a circuit that we’ve removed from a car for clarity. The positive battery terminal is connected to the positive terminal of the fan. The fan’s negative terminal is connected to the meter’s red lead, and the meter’s black lead is connected to the negative battery terminal. You can’t read the meter’s display, but it is showing about 5 amps. - Source: Internet
• First, you will need to connect the positive lead of the multimeter to the positive terminal of the battery. Next, you will need to connect the negative lead of the multimeter to the negative terminal of the battery. Finally, you will need to turn on the multimeter and set it to the amperage setting. - Source: Internet
• If you are testing a 6V battery a good battery will show a reading of between 4V to 6V. Anything less than 3.5V can show that the battery is dead and will need replacing. A general rule of thumb is if the level of voltage reads half or less than the specified voltage the battery is considered dead and not fit for use. - Source: Internet
• The multimeter will then display the current amperage of the battery. If the battery is able to provide enough power to start your vehicle, the amperage should be around 12 volts. If the amperage is lower than 12 volts, it may not be able to provide enough power to start your vehicle. - 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
• 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
• While the engine is running, the voltmeter should measure between 13.6 and 14.7 volts. For a rested battery, this should be around 12.6 volts. - Source: Internet
• 4. Finally, read the number that appears on the multimeter display. This is the voltage of your battery. - Source: Internet
• We measure the battery voltage with the vehicle stopped, off and without the key in the ignition. The voltage must be between 12,5 and 12,9 volts with the multimeter in direct current connected to the battery terminals. We start the car and leave it in neutral. - Source: Internet
• Whenever possible, connect the meter on the ground side of the circuit. It’s the same reasoning you employ when, while replacing the battery, you should always disconnect the negative terminal first and connect it last. For a current measurement, the meter will be in series with the circuit, so the probe leads are as live as any wire in the circuit. If you connect the meter on the ground side of the circuit (as per the illustration above), completing the circuit to ground will cause power to flow if the circuit wasn’t turned off, yet it can’t cause a dead short of a live power wire to ground because the meter is already on the ground side. In contrast, if you connect the meter to the positive side of the circuit and accidentally touch a probe lead to ground, it’ll cause a dead short of power to ground, which is sure to blow up the meter’s fuse or the meter itself. - Source: Internet
• Car batteries are in charge of powering all of a car’s electrical components. When it is full, you should have no problems utilizing it. However, issues with the battery can disrupt all critical electrical functions, including the engine’s cranking. - Source: Internet
• -If the equipment is given more volts, it can burn the equipment. -If the equipment is given less volts, simply that the equipment will not work. -If the source has more amperage than the equipment, honey on flakes. -If the source has less amperage than the one consumed by the equipment, the source is in danger. - Source: Internet
• A clamp meter is an easy way to test the amperage of your car battery. This device performs the same function as a standard digital multimeter. Just clamp this device over the positive wire and check the reading on its monitor. - 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
• 4. Check Engine light is on: In some cars, the Check Engine light will come on if the battery voltage is low. So if you see this light illuminated on your dash, it’s a good idea to get your battery checked out. - Source: Internet

• A bad battery is usually to blame for the delayed start of a car engine. If it takes forever for your vehicle to get moving, a multimeter battery test is in order. If jump-starting your car doesn’t work, a trip to the mechanic is probably necessary. - Source: Internet
• Note that whether either of the two amperage sockets have an internal fuse varies meter to meter. On some meters, both are fused. On others, only the high amperage (10A) socket is fused. On many inexpensive meters, neither is fused. This means that if you, for example, connect the meter to a circuit with a 20 amp draw, you can blow up the meter. - 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
