One of the most important parts of any car is the battery and by knowing the correct car battery voltage, you can easily check that it is charged and in good condition. These voltages are readings that are for standard lead-acid batteries and low maintenance batteries that are inexpensive and common in older vehicles. These voltages apply to the more expensive and modern maintenance free, glass mat and gel batteries.
It is important to know the normal car battery voltage so that you can do, a simple car battery voltage test and be able to see if your battery has a charging problem. There are a range of devices that you can use if you want to test your car battery voltage or state of charge. Everybody loves their cars, and most people just want their cars to be well looked after and loved. So, if you’re vacationing in New York and looking for car rental deals, you need look no further than Brooklyn. Mahalo mechanic expert Desmond Bryant teaches you how to check your car battery's fluid level.
A dry cell battery has a rod called a cathode at its center, generally made of metal or graphite.
Please remember that using others' images on the web without their permission is not very nice. Car Air Conditioning SpecialistsAs the UK gets hotter the benefits of air-conditioning are gradually being accepted. MOT TestingWe are accredited by VOSA and can MOT class 4(cars, motor home) Class V and Class VII.

We keep a large range of car batteries in stock at all times, covering over 95% of vehicles on the road today.
It can confuse many people, as they believe that a normal car battery would be charged when it is at 12 volts and empty when it is at 0 volts. These are found on most modern vehicles and are available as replacements for older models. One point to consider is that temperature can have a dramatic effect on voltage with cooler temperature dropping voltage and the figures shown above are applicable to 70 degrees Fahrenheit. If you have a multi-meter then it is quick and simple to attach the leads to the positive and negative terminals of the battery. These allow you to test the battery under load and give more information about the health of the battery. It was the most common way to test batteries before electronic test equipment became common outside of garages. Now the additional benefits that are not immediately obvious are now being appreciated by those fortunate to have a good aircon system operating in their car.

This is not true and in fact, there is a very small range around 12 volts where the car battery voltage moves from fully charged to fully discharged.
There are many factors that will affect the life of your battery, so the only real way to see if the battery is good still is to test it. Your battery should be at or very close to the fully charged voltages that we have listed for common battery types.
This is done by putting the battery under stress and then measuring how much the voltage drops during the process. The device is only useable in batteries that are not sealed and allow you to access the acid solution inside the battery. The cathode and paste are wrapped in paper or cardboard (known as a cell) before being sealed into a metal cylinder called an anode. If there is a reading below the normal car battery voltage level then the battery or charging system may need to be checked. This test should be done yearly before the cooler winter months that will put the most strain on the battery.
The tester looks like a giant eyedropper and you simply suck in enough liquid to raise the measuring float. When a device is connected to the terminals, a chemical reaction occurs between the cathode and the paste to produce about 1.5 volts of electricity.
