Factors to Consider When Looking For The Best Car Battery

In this guide, we have provided you some of the finest car batteries of today. But while knowing which batteries are the top-rated ones is very helpful, you may also need to know that factors that need to be considered first.

When you get to learn these factors, you will definitely know which battery will best work for you and your car.

1. Type of the Battery

Today, car batteries come in two basic types. The first type is the regular one which is very convenient for car owners. And this is because they don’t need maintenance.
Apparently, regular car batteries or the Lead-Acid types are usually the ones that require owners to periodically top off the water in the solution. This is because the liquid is where the power comes from.
Usually, these batteries are much inexpensive than the other type. However, they do not possess the same power as the other type of batteries would have. In addition, they cannot hold a charge for as much as the others can. Furthermore, they cannot tolerate a deep discharge.
On the other hand, Absorbed Glass Mat or AGM is the much more improved car batteries. They are actually designed to provide enough power to sustain different kinds of innovative features.
Today, AGM is considered to become a fully-conventional car battery as well. The reason behind this is that cars of today have become very innovative and advanced. They have features like power outlets for gadgets and electronic safety that would require much more power. And AGM can provide that amount of power.
However, the prices of these batteries are 40 to 100% higher than the Lead-Acid types. So, it would really require you a fortune. But, its quality would normally justify its price.

2. Size of the Battery

The size of the battery is one of the most important factors to consider. This is because batteries come in different sizes and dimensions. And as it happens, there is a specific size of battery that is designed for you car.
size of the battery
In short, you have to learn the size of your car’s battery tray.
Normally, the size of a car battery is comprised of the length, width, and height. And you can learn these figures by checking the manual of your current or previous battery.
But if in case that you do not have the manual, or you don’t know the exact size that your car requires (which rarely happens for car owners), you may want to consult a mechanic too.
Normally, these are the typical sizes of a car battery:
24/24F (Top Terminal): This size of battery is ideal for Toyota, Honda, Lexus, Infiniti, Nissan, and Acura vehicles.
34/78 (Dual Terminal): This kind of battery is perfect for large Chrysler vehicles. Also, they are very apparent to several 1996 to 2000 Gm Pickups, SUVs, and large sedans.
35 (Top Terminal): This is ideal for most Japanese nameplates. Normally, these include the most recent Honda and Nissan vehicles. It can be ideal as well for some Subaru and Toyota vehicles too.
47-H5 (Top Terminal): Perfect for several Volkswagen, Fiat, Buick, and Chevrolet vehicles.
48-H6 (Top Terminal): This car battery size can fit most European and American-made vehicles. These include BMW, Buick, Cadillac, GMC, Mercedes-Benz, Audi, and Volvo.
49-H8 (Top Terminal): Ideal for several European and Asian-made vehicles like Hyundai, BMW, Audi, and Mercedes-Benz.
51R (Top Terminal): Perfect for several Japanese vehicles like Nissan, Mazda, and Honda.
65 (Top Terminal): This battery size is designed for large trucks, cars, and sport-utility vehicles from Mercury or Ford.
75 (Side Terminal): This is ideal for General Motors that are mid-sizes and compact. Also, there are cases that this battery fits a few Chrysler vehicles.

3. Power

The power of a battery specifically points the Cold Cranking Amps and Cranking Amps.
By and large, Cranking Amps is the energy that your car needs in order for it to start at a temperature rating of 32 degrees Fahrenheit.
On the other hand, Cold Cranking Amps is mainly the energy that your car needs to start at a temperature rating of 0 degrees Fahrenheit. And it is usually applicable and recommended to vehicles in areas where cold weather and cold temperatures is very rampant.

4. Positive and Type of Terminals

Keep in mind that the position of the terminal affects dramatically the polarity of your car.
Depending on the type of your car, the positive terminal is located either on the left or right side. This is very crucial for you to know since there is a huge chance of shorting when the positive terminal makes contact with a metal material.

5. Battery Life

Generally, the life of a car battery can last from three to five years. But, keep in mind that it actually varies from one battery to another and one vehicle to another. This is because there are a lot of things that affect the lifespan of a car battery. Nevertheless, it will still drain the life out if in the end due to its overall composition.

battery life
In totality, the two biggest factors that affect the battery life is your driving methods and the surrounding temperature.

Surrounding Temperature

When you are located in an area where the surrounding temperature is quite hot, the battery life tends to have a much lesser lifespan. As it happens, car batteries are situated under the hood. And the surrounding temperature in it is already hot. But even so, these batteries can stand such heat ratings.

But, if you are to drive always on locations where there is intense heat, the fluid that provides the overall charges inside the battery dries up. And keep in mind that once it dries, it can begin to discharge the battery within 48 hours.
So, be careful when driving in hot regions or during the summer.
The same is actually true for cold surrounding temperature. You would normally notice this when you experience having a hard time starting your engine. This is because cold temperature makes it quite difficult for the battery to start its initial burst of energy.

Moreover, cold weathers thicken the engine oil. And this is not essentially helpful. Although cold weathers and temperature ratings have an impact on the life of the battery, it is not as serious as what higher temperatures can provide.

Driving Habits

But while the surrounding temperature is a factor that you cannot control, you definitely have a control over your driving habits.

Apparently, your driving habits also play a huge role in the life of the battery. When you drive for short periods of time, regularly, say start and stop within 20 minutes, you use the power of the battery and not allowing it to recharge itself.

This kind of habit actually drains the battery in a much shorter period of time.

6. Features and Accessories

When you purchase car batteries, it is always practical to look out for its accompanying accessories. Usually, these accessories will help you to get the most out of your chosen car battery. Moreover, this can help you maintain and prolong the lifespan of the battery.

Although some packages would include several additional accessories, there are only two to three essential things to look out for:

Handle or Loop

One of the most essential accessories that you must look for when purchasing a car battery is the handle or loop. Some car batteries do not possess handles or loops which makes it inconvenient for the users to bring down the battery in the engine.
Normally, these handles or loops can accommodate from 40 to 60 pounds of weight. So, having this accessory can largely help you when you are bringing down the battery in the engine.

Trickle Charger

When you are leaving your car or vehicle in store for a very long time or you won’t use the vehicle for some time, it is very practical to keep a trickle charger with you. This will automatically recharge the battery so it would not be discharged when the car is not in use.

Some trickle chargers possess features like a built-in circuitry. And this is a very useful feature if you think that you cannot check the vehicle upon storing it. Apparently, this feature will automatically recharge and stop the charging period when the battery is already full.

It is important for you to note that when car batteries are overcharged, they tend to be very susceptible to breakage. And this will be much more costly since it could result in replacements.

But, if in case that you will be able to check the car or the vehicle, along with its batteries when the car is not in use, there is no need for you to require your trickle charge with a built-in circuitry.

Jump Starter

A jump starter is a very essential tool to have in your car emergency kit. When the battery discharges accidentally, you will surely need a jump starter to restart the initial burst of energy to start your engine.

Although most people would choose to connect the cars with other vehicles, a jump starter will omit this kind of inconvenience. Hence, it is very practical for every car owner to have this car battery accessory in their kits.

7. Maintenance Methods

The best car battery is usually divided into two categories when it comes to maintenance. Firstly, there are car batteries that require no maintenance. On the other hand, there are car batteries that require low maintenance methods.

The ones that require low maintenance methods would involve adding distilled water in it, every now and then. And due to this kind of feature, these types of car batteries are normally unsealed with a cap.

As for the batteries that do not require maintenance at all, they are actually sealed with caps. And the liquid electrolyte included in the battery is already sufficient all throughout its lifespan. Plus, you no longer need a replacement.

8. Warranty Terms

Another important factor that you need to consider is the warranty term for the overall package. It is always practical for you to choose the batteries that come with much longer warranty terms, including its replacement periods.

Normally, the ones that have a great warranty term are the ones that you can trust. So, be very mindful of these things before purchasing your chosen car battery.

Replacements: When To Replace?

Sooner or later, you will need to replace your car battery. And as much as you want to save up, there will come a time that this is essentially required. And no matter how you keep it well maintained, all car batteries will need a replacement.

But, more often than not, car owners do not entirely know when to replace their batteries. So, in order for you to avoid these kinds of inconveniences, you might want to learn the symptoms and signs that your battery already needs replacing:

Check Engine Lights Indicator

Some vehicles feature a Check Engine Light in its dashboard. Apparently, when this light turns on, it only indicates that your battery is already in its weak state.

In some cases, some or a few of your indicator lights like the coolant indicator would turn on due to the poor quality of the battery. And there are cases as well that this could mean that there is already a problem with your battery.

So, when some of your indicators turn on or warn you as you use the car, try to check your engine, especially your battery.

Sluggish Engine Crank

Another indicator that would mean your car battery needs replacing is when the cranking of the engine starts to become slow. Also, it might take you a while to start your engine when the battery is already weak and dry.

As for the sound, you will also notice that the sound your engine makes is quite different from the normal starting sound.

Unpleasant Smell

When you notice an unpleasant smell as you check your engine, it only means that the battery has already started to leak. The unpleasant smell that is present is actually caused by the sulfur. And when this happens, it means that you already need to replace the battery as it might negatively affect the other parts of the engine.

Low Battery Fluid Level

Normally, car batteries have an indicator in its casing which you can utilize to keep an eye on the fluid level. When the fluid level has reached below the lead plates, you might already need to replace the battery.

But, you must also perform several tests first before deciding to replace your battery. It may save you costs and time too.

Third-Year Functionality

When your car battery has reached its third year of functionality, it is normally considered as an old type already.

Although there are batteries that can last for 4 to 5 years or even more, it is a must that you keep an eye on all the indicators, symptoms, and signs to avoid further inconvenience on your end.

In short, once your battery is already in its third year, prepare yourself already for a much sooner replacement.

The Verdict: The Best Car Battery Among All

All of the car batteries included in this list are great and fully-functional. But, there is only one that stands out among all. And this is the Odyssey PC 1500DT Automotive and LTV Battery.
Primarily, this car battery features a superior quality that cannot be compared with the other car batteries. Secondly, it comes with a very effective warranty term and service life. In fact, the warranty of this model is valid for up to 4 years. As for the service life, it can range between 3 and 10 years.

Although this model is quite expensive, you will surely get what you pay for. And personally, we think that this battery is really worth the price.

Final Thoughts

Choosing the best car batteries is very challenging and difficult. Aside from the fact that there are quite a lot to choose from, there are also a lot of factors to regard. And more often than not, these factors are entirely technical.

Most car owners of today are not largely tech-savvy which, at times, can be really tricky in buying car batteries. But even so, it is still important that you learn the important details in choosing a car battery for your vehicle.

Learning these aspects will help you choose the most appropriate type for you. But if in case you are still having difficulties, it is still practical to ask for consultation and assistance from your local service provider.

Talk to mechanics or even car specialists. Certainly, they will help you when it comes to choosing the best battery car for you and your vehicle.

Also, it is best that you check first your battery before heading out and make a purchase. Sometimes, all you need to do is to clean and have it checked by specialists.
