Has your car stopped? Now you are all alone in the middle of nowhere and wondering about what to do with your battery.
Is your battery dead, but the electrical systems and lights are working well? It’s the perfect sign showing that your battery will need a kick start? Identifying which side of the battery is negative and positive is a simple task yet important to jump-start.
Before we start with the pos neg battery terminals, let’s dive into finding out what exactly battery terminals are present on the battery. They are the type of electrical connections that are used for connecting a charger or a load with a single or multi-cell battery. The terminals on the battery come in various sizes, features, and designs.
Which terminal of the battery is negative and negative?
The battery’s negative terminal is black colour-coded and connected with the minus sign of the battery. The negative or minus sign is printed over the battery’s plastic coating, so you should look closely and identify the signs. The battery’s negative terminal might have a plastic cover or lack the plastic layer over the terminal connector.
The wiring insulator on the negative side is black coloured with the negative terminal directly attached to the car’s metal chassis.
On the other hand, the battery’s positive terminal is red in colour and is connected with the positive side of the battery. The plus or positive sign is printed over the battery plastic coating, and it might be challenging to spot the signs.
The positive terminal also has a red plastic cover coating over the terminal and is likely marked with a positive sign. The plus or the positive wiring insulator is coloured red.
What side is negative on a car battery?
The negative side of the pos neg battery is always
s black. But you might find the negative cable to appear black as well. That’s why it’s always essential to look for plus and minus signs which are stamped over the battery case.
Some individuals usually wonder that black always negative on car batteries, so the answer is YES in most cases. The black cover on the negative terminal prevents any accidental shorting.
Sometimes the cover is not there, so you need clues like plus and minus signs stamped over the case.
The minus sign definitely indicates the negative side of the car battery.
What is the negative terminal of a battery called?
There is a metallic or plastic case with an anode and cathode on the inner side of a working battery. And cathode is then connected with a positive terminal, whereas an anode is connected with a negative terminal. These parts are known as electrodes, and they are the parts that conduct chemical reactions.
If there is a non-rechargeable battery, the negative terminal is where all oxidation is conducted in the battery when it results in a discharge connected with the load. The oxidation then leads to the release of negatively charged ions, which are known as electrons exiting the battery at the negative pole.
In electrochemical language, the pole where the electrons leave the battery is termed an anode. The exit of the electrons from the battery towards the load gives the negative terminal of a battery, a name known as the anode.
On the other hand, the positive side or the positive terminal is known as a cathode. It’s the part where there is reentrance of the electron after spending enough energy over external load. Once the electrons are inside the battery, they result in a reduction reaction due to which is known as the cathode.
In the rechargeable battery, the electron flow direction is reversed. In this, the electrons are pushed from the negative pole in the battery and exit the battery’s positive pole leading to the change of terms anode and cathode.
The negative terminal/ black coloured terminal is also called the ground terminal. This is the terminal of the battery, which is connected with the vehicle chassis.
Our car battery terminals always on the same side?
To determine which side of the car battery terminal is negative and which is positive is usually straightforward in terms of colours and signs. But if you are unable to distinguish and have mixed up the set of jump leads or cables, you can damage the vehicle. However, most of the automakers usually make it simpler and comfortable for the users to identify the negative and positive car battery terminals.
There are different types of car battery terminals, depending on their configuration. The right configuration of the terminals in car batteries is essential to identify to prevent any accidents.
- SAE battery terminal- it is one of the standard configurations in most vehicles. The SAE terminal consists of multiple lead posts in a truncated cone shape present over the battery top.
- This SAE terminal features lead posts with a slight difference in diameter, ensuring correct electrical polarity.
- JIS battery terminal- this terminal has similarities with the SAE terminal, but it’s smaller. It also features a larger positive terminal than the negative terminal, but both of these terminals are tinier in size as compared to the SAE counterparts. Most of the older versions of Japanese vehicles were installed with a JIS terminal.
- L- battery terminals comprise an L-shaped battery post with a bolt hole running through the vertical side. These terminals are usually used in certain European cars, lawn and garden devices, motorcycles, snowmobiles, and some other light-duty vehicles.
- Marine Battery terminals- these terminals come with typical two posts. The negative post is 5/16”-18 post while the positive post is 3/8′-16 post, which helps in distinguishing the two terminals.
How to jumpstart your car if the battery is dead?
Have a look at the following simple steps to get started and achieve a running battery:
Look for a perfect set of jumper cables:
Find a set of jump leads or jumper cables along with another vehicle that has a running battery. You can get these cables from auto parts stores, gas stations, and others.
Park your car nearby close to the vehicle with a charged battery:
Park the car near to the vehicle with a charged battery. The vehicle should be close enough so that the cables can reach easily. Shut down the engines of both vehicles and open the trunks or hoods where the battery is located.
Identify both positive and negative car battery terminals:
Identify the positive (red) or negative (black) terminals on the battery. One terminal on the battery is marked + while the other is marked -. you also have two terminals in jumper cables, including positive and negative.
Look for the metal ground to have supported:
Now identify metal ground in a vehicle that has a dead battery. Use that metal frame.
Attach positive cable to the positive terminal and negative jumper cable to negative terminal:
Attach positive cable to the positive terminal on the car battery while negative jumper cable to the battery’s negative terminal. And do the same with other sides and connect it to the charged battery.
Now start the car having charged battery:
Start the car which has a charged battery, and then after 2-3 minutes, start the vehicle which has a dead battery.
Remove the negative metal clamp from the vehicle with a dead battery:
Now remove the black, negative metal clamp from the vehicle that needed the jump and then remove the assisting vehicle’s negative clam.
Remove the positive clamp from the assisted car having charged battery and then move to the dead one:
Now remove the red, positive clamp from the vehicle, which helped remove the formerly dead car’s positive clamp.
(Always remember to remove positive first and then negative. When you disconnect cables from an old battery, it’s recommended to remove negative first and then positive. While the connection to the new battery should be in reverse order, which is positive first and then negative)
Other than these steps, you can also try using a wire brush for cleaning the dirt, debris, and corrosion from the battery terminals along with the cable clamps. The wire brush seems perfect for external cleaning of clamps and cleaning of the terminal posts.

Are you still confused about the jumper cables, negative and positive terminal of your car battery? Then no worries, as you can also check out the owner’s manual and find out the detailed instructions listed on it in terms of battery car and jump-starting.
If you don’t have the user manual, make sure to check the digital version available online on the manufacturer’s website.
