What exactly does a car battery mean?
A battery is a small component of your vehicle; however, despite the sleek size, it’s a powerful product that every car must-have. A battery is mounted inside the car by a professional installer. However, every driver needs to have these skills in case of an emergency.
As an essential component of an automobile, it offers electric power to electrical parts of your car. In simple words, a battery is the heart of every vehicle and without it, then your car won’t start.
Inside the battery, there are cells that convert chemical energy into electricity. Normally, when this happens, there will be a chemical reaction, which then produces power that propels the car to move.
What does the battery in a car do?
Majority of car batteries use lead acid which is the main component. This is a solution which causes the cells to have a chemical reaction and get your car to move and operate normally.
When electricity is supplied to your car through the cells, you can enjoy using important devices such as the radio, which will keep you entertained in your journey. Additionally, it ignites the car’s light and wipers while setting your car into motion.
The battery puts your engine into action, making it bubble with life with the help of an alternator. It keeps your car energy for a startup for the next time you want to take a ride.
It acts as the storage of chemical material to be converted to electrical energy needed by the car to start. There is no need to worry when your car produces a sound when you ignite the engine. Failure to produce the sound could mean that there’s less energy to make it run.

Types/varieties of car batteries
The following are types of batteries.
a) Lead-acid battery
Lead-acid is also known as flooded-battery. Many people go for it because it is cheaper compared to the recent models of batteries. The only challenge it has is that it has low energy. It is rechargeable and has lead-acid, which is stored up as liquid.
b) SLI batteries
SLI is an acronym for Starting/ Lighting/Ignition. As the name suggests, these batteries start your engine, light your car, and turn on the car radio. Most of the batteries in the market are SLI.
This type has the nominal capacity, also known as rated capacity, which is the storage section that determines the amount of energy it stores. It can be removed from it when it is fully charged and is a predictable current that does not fluctuate.
c) Deep-cycle battery
These types of batteries can be recharged and discharged while maintaining quality. They provide a decent amount of current for long term use. Before using this type of battery, it is essential to know if it has the strength to start your car engine.
To determine if the power is sufficient, you can use CCA or the Cold Crank Amps rating, which helps define the ability of a battery to start the car engine, especially in cold temperatures.
d) Lithium-ion battery
It’s also known as a Li-on battery and is a rechargeable battery mostly used by electric vehicles. It has a high voltage and requires a protective circuit. They are charged in cooler temperatures; hence it’s advisable to avoid charging it in high temperatures as it would quickly destroy it.
How does a car battery work?
As seen earlier, in a car battery, the cells cause a chemical reaction to produce electrical power. Subsequently, your car’s engine receives this energy and can start the car. Therefore, a battery is a key part of your vehicle and without it, the car won’t move one bit.
Normally, your car battery has a total of two volts, and this works together to provide enough energy for the engine to start. The cells have plates that are immersed in a lead substance. After immersion, the plates move, and the next action is to activate the liquid in a powerful process that converts the chemical to electric energy.
Should the battery fail to charge, you can use the terminals and connector cables to jump start your vehicle. When you take a close look at your battery, you’ll notice cone-shaped devices mounted onto your car battery.
Those are terminals and are either positive or negative. Some caution is needed, and you should always connect the positive, which is red first because if you start with the negative, which is black, you will be part of the circuit, especially if you are touching any metal part of the car. It’s dangerous and can harm you.
Ways in which you can take care of your car batteries
Below here are the benefits of installing a remote starter for your vehicle.
- It’s important to avoid parking your car for long without starting it as it can make the battery fail to charge fully. Drive your vehicle regularly and for long-distance so that it is fully charged. Make sure it is correctly charged for better performance.
- Ensure your car lights are turned off when not in use because they take a toll on your battery.
- If you are not riding the car, try and avoid using your radio or charging your phone because it will waste your battery functionality.
- Clean the battery terminals because they are likely to rust with time, causing them not to function correctly. You can polish it with a soft brush. Also, make sure they are well placed the positive and the negative.
- Just like your body needs a check-up now and then even if you are not sick, so does your battery. Keep a good look at it and other vehicle parts so that it gives you longer service.
Battery life and how to improve it?
- A good battery can serve you between 2 to 7 years; depending on how well you take care of it and how often you use your car. Exposure to extreme heat conditions spoils the battery. If you can, do not expose it to direct sunlight.
- On the other hand, too much cold is not good for your battery. You might consider wrapping it with a warm cloth to prevent damage.
- Your battery should be firmly fitted to avoid vibrations, especially if you are riding on a rough road. The hold-down bar should be tightly fixed so that the battery does not shake too much. Look for leakages because if there is, your battery will not work as expected, and it will likely wear out fast. Read more: ways to prolong the life of your car battery
Are car batteries bad for the environment?
As discussed earlier in our review, batteries contain toxins that produce chemical reactions for a car to start. A battery is not a recyclable product, and when decomposing, it releases the chemicals.
Therefore, if you dispose of a battery wrongfully, it will produce greenhouse gases that affect the climate. The harmful chemicals are transported to water bodies like rivers and lakes by rainwater.
Although batteries are essential and make your car to move, they are a necessary evil. It means that people need them yet; they are bad for the environment. Hence there’s a need for a proper and sustainable disposal system that protects the environment.
Although they pollute the environment, the electric batteries are less harmful than the combustion-engine ones. They are specially designed so that they provide a safe pathway that minimizes the emission of greenhouse gases. Hence, if you care about environment conversation, consider the electric options as they are safer.
