Car Battery Buying Guide

Car Battery Reviews

If you have come to this point –the beginning of our car battery guide, then there must be lots of questions buzzing around your head. We know exactly how it feels when you are not confident enough when it comes to purchasing a car battery. There are so many things to think about, so many brands and lots of manipulative traders trying to convince you into buying their product.
That is why our team has collected and summed up the essential information. Such info will help you understand your car’s needs when it comes to car batteries.

What To Consider Before Buying a Car Battery

See the questions below to make yourself familiar with the facts and details we have prepared for you. They will definitely give you food for thought before heading to the store to make an informed choice.

  • What types of batteries are there on the market?
  • Are there any distinctive features to consider?
  • Is the car battery going to perform well in your climate area, for example, very hot or cold weather?
  • How to take good care of a car’s power unit in the winter?
  • What maintenance is needed for a car battery to work well during its service life?
  • How to charge a car battery the proper way?
  • Which is the best brand for your car?

You will find answers to these questions as well as a lot more in the following sections of our guide. So, let’s get started!

Car Batteries’ Essential Features And Specifications

Since we have already explained that there are several main types of car batteries, it is time to talk about the most essential characteristics of such power units. This will help you choose the right power unit for your car. And moreover, you will save yourself that feeling of confusion at the sight of so many car batteries that look the same in the car parts store.
But first, make sure to check your owner’s manual about the specifications for your car. This will ensure a reasonable purchase of a car battery that fits your vehicle and also complies with its individual characteristics and power demands.
So, what do you need to look for?

  1. Cranking Amps Rate (c/a) & Cold Cranking Amp (CCA)

    All car batteries come with a specified number of their ability to do work or in other words, how well your engine will start. Therefore, the higher the number, the better. However, cranking amps rate is just the status of a car battery’s performance at 32°F. So, c/a may look impressive, but it is not that reliable.
    What you should really pay attention to is the cold cranking amps rate (CCA). This shows how well your engine will start in freezing weather. CCA begins from 0°F and hence, the bigger the number on your chosen car battery, the better it will be for your car.
    Also, bear in mind that cars running on diesel need a lot of power to be ignited. If you decide to buy a car battery with lower Amps, despite the recommended rate in your owner’s manual, you will still be able to start your vehicle. But the problem will come later because your battery will not last long. That is why you should always get the CCA correct for your car.

  2. Reserve Capacity ( RC)

    This is another critical number to check on your chosen car battery. This number shows how long a brand new power unit can supply energy without being replenished by the alternator. In other words, how much time you have before the car battery goes dead.
    This is important since all car systems are computerized, and hence, they draw power from the battery. That is why you may want to get the longest RC that you can get. However, you should find a happy medium between the biggest CCA and RC ratings if you’re going to enjoy long hours of a steady working car battery.

  3. Battery Specifications

    There are a few things to check about the power unit – the battery life and whether it is fresh. Here is some more info on these features.

    • Battery Life
      The total capacity of your power unit is measured in Amps per hour. In other words, this is how long your battery is going to last. For example, if you were sitting in your car and listening to the radio, then that number would show you how long you would be able to do that.
      The biggest thing that takes the most power out of your battery is starting your vehicle. Therefore, these amps are essential to tell you how many times you can turn the ignition on. For instance, if you have stopped and let your engine running, then there would be no load on the battery. This is because the alternator is actually taking care of such things.
      But in case you make a lot of trips and need to constantly start the engine and then stop it, let’s say for 20 times per day, you will need a higher amp battery since it will be more robust. Also, the power of the battery to run on its own steam will be longer, which will guarantee a prolonged battery life.

      However, if you have a lazy start and got the right amps, then the problem is your car, not the battery. You should check this option in the first place before heading to your car mechanic. Just raise your vehicle off the ground on your car ramp to have a better look at your car’s undercarriage and ensure that everything is well-maintained and in order.
      If you don’t have such device, then don’t miss out our car ramps reviews and buying guide for more detailed information and practical tips.
    • Getting A Fresh Battery
      You may have already guessed that the more a battery stays in the store, the more it loses its power. That is why you should always check the shipping code on the power box. It will not be ok for you and your car to buy a battery that has spent more than 6 months in storage.
      So, the months are represented by letters, like A, B and so on, and the year as a number. In other words, if you see C7, for example, then your battery was manufactured in March 2017.
  4. Warranty

    It is always better to buy a product that is supported by a long-term guarantee. This will give you confidence and ensure that your chosen unit will be worth the money and its performance. Many manufacturers usually provide 1 or 2 years guarantee that their product will work at its best and offer a replacement if their car battery does not live up to your expectations.

  5. Size

    Since cars come in different sizes, the same goes for their battery trays. Due to this fact, you should check the measurements to get the right fit. The terminals have to be in their exact place to ensure that the cables are fixed correctly.

Types Of Car Batteries

Best Car BatteryIn this section of our guide, we will give you some basic knowledge of the different types of lead-acid batteries available on the market. Our team is aware that you do not need extensive technological characteristics, so we have kept it short but quite comprehensive.

  1. Flooded-lead Acid Batteries

    This class of car batteries is actually the most common type. They are reasonably-priced, ideal for turning your car’s ignition and great for the power load of your car’s accessories. However, we are not talking about car brands with lots of electronic features such as seat heating systems, DVD players, GPS systems, etc. Open-style car batteries just cannot keep up to such colossal power consumption.
    There a few things that you need to remember, though. Since this type of car batteries are not sealed, they need a lot of maintenance. The reason for this is the design of the battery box as well as the placement of the lead plates and acid inside.
    The valves, which are situated at the top of the battery box, are an excellent example of why such batteries require regular upkeep. Such a design will make it easier for you to look inside and check the water level. And if you notice that it is too low, you should add distilled water immediately.
    This step is crucial as it will help your car battery last longer. In case you forget to ensure there is enough water in the battery box, you may end up with a dead battery. This flooded-lead acid car battery has some positive and negative characteristics which we have summarized here.
    ADVANTAGES

    • Low-priced
    • Great for starting your vehicle
    • Enough power for standard electrical loads of your car accessories
    • Good for all weather conditions
    • Suitable for most OEM applications

    DISADVANTAGES

    • Requires maintenance
    • Can be damaged if there is a strong vibration
    • The separator can be pierced
    • No flexibility in mounting as the liquid may be spilled
  2. Sealed Car Batteries

    This type of car batteries is also known as MF or maintenance-free. There is no need for adding water or checking levels of liquid inside. This is good news for those of you who are not that diligent and forget to make sure there is still enough water in their car battery.
    Sealed car batteries are equipped with vents. However, in this case, the openings are made to let the gasses out of the car battery. These vents are tiny, so they will lose water a lot slower than the flooded-lead acid type. But eventually sealed car batteries will run out of acid inside, and you will have to replace it. Still, the fluid will last for the entire service life of the car battery.
    ADVANTAGES

    • No maintenance needed
    • Keeps gassing to a minimum
    • The acid will stay till the end of the battery service life
    • Great for lightly used cars
    • Mounting flexibility

    DISADVANTAGES

    • Shorter life
    • Cannot power too many electrical features in your car
  3. Calcium-Calcium Car Battery

    It is easy to see how this type of vehicle battery got its name. The plates inside the box are made of calcium alloy, which will guarantee 80% decrease in fluid loss. Also, this type of car power unit has lower self-discharge. This means that, if you haven’t used your car for months and then try to start the engine, you can rev up your vehicle without a problem.
    Another great thing about this type of battery is that you can get a higher cold cranking amps rate. Calcium-calcium car batteries may not lose their charge that quickly, but they are more challenging when it comes to charging.
    Moreover, since the plates in the car battery are made of calcium, you can expect some adverse chemical reactions. There might be a growing grid corrosion process inside the box, or the plates may get covered with chemically inactive lead sulfate. And all this can lead to malfunctioning car battery despite being fully charged.
    Needless to say, properly charging your car battery is essential to keep it in good condition during its service life. So, make sure that you have the right battery charger for your car’s power unit. If you are still not sure how to choose this device, or why it is so important, check out our thorough car battery charger buying guide. You will find lots of practical advice, tips, and extensive explanations on this topic.
    ADVANTAGES

    • 80% lower fluid loss
    • Lower self-discharge
    • No maintenance needed
    • Higher CCA
    • Standard flooded

    DISADVANTAGES

    • Charging is a challenge
    • Chemical reactions may affect the power unit’s performance
    • Shorter service life
    • Basic cycling capacity
  4. Gel Car Battery

    This type of car batteries comes with silicone alloy, which is added to the acid. This is done to ensure that the gel solidifies in a gel-like substance. As a result, the mixture will not let the acid leak out of the box. And thanks to this chemical reaction, gel car batteries have a high capacity and are a safer option to use. What is more, gel car batteries are very durable and can withstand over-charging. However, they are mostly found in golf carts.
    Gel car batteries’ power is kept within the bounds of a regular start battery. This means that these units are not protected from overheating. Therefore, you simply can’t expect gel power units to be fully charged with a conventional car charger.
    ADVANTAGES

    • Robust
    • Big capacity
    • Cannot spill acid
    • Withstand over-discharging
    • Great for a starter battery
    • Eliminate fluid loss dramatically

    DISADVANTAGES

    • Should be charged at a slower rate
    • Limited to only starter car batteries
    • Cannot be used with traditional chargers
  5. Absorbed Glass Mat Car Batteries

    Well, this is perhaps the most attractive option to choose for a car battery. The battery box has safety valves where the oxygen and hydrogen react with each other. As a result, they are turned into water, which decreases the fluid loss a lot.
    However, the most distinguishable feature of AGM batteries is the fiberglass mat. It functions as a sponge that keeps the electrolyte and holds it in the fiberglass mat. This means that there will be less internal resistance, which will result in a better flow of electrons. Moreover, this technology will protect the environment as it does not release any gasses into the atmosphere.
    Another great feature of the AGM car power units is that they are resistant to vibration. This is because the fiberglass mat is placed in a cylindrical case, which will ensure it stays steady.
    AGM car batteries are also the preferred choice for the start-stop vehicle technology as it has sufficient power to support higher electrical demands. That said, you can use such a car battery for powering all your electrical features like heated seats, audio systems, GPS navigation, and many more.
    ADVANTAGES

    • Perfect for all weather conditions, especially severe ones
    • Support high electricity loads
    • Great for start-stop vehicles
    • No gassing into the atmosphere
    • Maintenance-free
    • Flexibility in mounting
    • Allows higher CCA
    • Vibration-resistant

    DISADVANTAGES

    • Very expensive
    • Limited amount of acids

Cold Weather And Car Batteries

Cold weather is the enemy of any car batteries because it takes the life of your power unit at 30°F. This way, you lose about 35% of your battery life. Moreover, at 0°F, you will lose even more than half of your battery power. Another adverse effect of extreme cold conditions is the fact that the acid in the battery solidifies and that makes it impossible to start your engine.

However, there are a few things to consider before buying a car battery which will help you avoid being stranded on the driveway.

  • CCA or cold-cranking amps
    As we have discussed the importance of CCA above, let us remind you again why this number is so crucial. The higher that number is, the more prepared and sturdy your battery will be for when temperatures dip below 0°F. That is because when you try to start your engine in cold weather, you will need more power.
  • Reserve capacity
    Since reserve capacity measures how long a battery can supply power, you should also take that number into consideration when it gets frigid in your area. Low temperatures mean that there will be a bigger draw from the starter. Moreover, all the electronic systems like the ones for heating the seats or the air conditioning will need more power to start working.
    In this case, make sure that your car battery has the needed reserve capacity to withstand harsh weather conditions to start the engine successfully. However, if your car battery has all the necessary power to turn on the ignition of your vehicle, but you still cannot move, check your tires. Low-pressure centers might be turned on, and you may need to change the wheels.
    The easiest way to this is by using an impact wrench. Make sure to check out our cordless impact wrench reviews where we have handpicked the newest and most effective products on the market. Choose the right one for you.

Winter Battery Care Tips

Cold weather conditions make it harder for you to start your car, and therefore, it takes a lot of the power of the battery. But before suggesting what you can do to take care of your vehicle during the winter, look at the warning signals that you need a new battery.

  • Sluggish start
  • Dim lights
  • Not starting at all
  • A car battery that hasn’t been replaced for more than 6 years

So, here is what you can do to ensure a quick start of your vehicle without any further complications in winter conditions.

  • Regular battery service to avoid capacity that is on the edge
  • Pick a battery that is for your vehicle’s specifications
  • Drive your car every day
  • Keep your vehicle in a garage to avoid freezing cold winds. If you do not have one, then make sure to park somewhere away from the main wind direction.

How Car Batteries Work

The car battery does not only generate power to start the engine, but it also makes its own when the motor runs. That is because it manages two absolutely opposed functions using the same components. The battery generates electricity and stores up power.
Here we are going to explain this process, and of course, tell you why this is important regarding your knowledge when buying and using a car battery.

Key Features Of A Car Battery’s Design

Each car battery has a positive and a negative terminal. They are connected to the car, and when you turn the ignition on, these terminals send a flow of electrons to power your car’s wipers, headlights, radio, and air conditioner. But most importantly, the electrons power your engine starter. But how does this happen?

  • The Cells

    Inside the battery, there are 6 small energy-producing units called cells. Each cell has 2 sets of electrodes, and they are made of 8 overlapping metallic plates. This makes a total of 16 per cell.

  • The Grid

    All the metallic plates form a compact grid. The bigger the grid’s overall surface, the more power it generates. The positive grid, covered in lead oxide, carries electrons in the negative grid, which is covered in the lead. This reaction releases the electrons needed to empower your car’s electrical systems, including your engine.

  • The Chemical Bath

    The lead-coated grids are soaked in a chemical bath. This solution always consists of sulfuric acid and water. However, the proportions may vary depending on the quality of the car battery. If you want a more powerful unit with a voltage of 12.6 V or more, then the acid should be more than 35%.

  • Chemical Reactions Inside Your Battery

    The key for a well-functioning car battery is all these three ingredients mentioned above to react with each other as the battery drains. The bath of water and the sulfur acid act as an electrolyte. This is a substance that conducts electricity.
    As the battery discharges, the acid bath reacts to the chemicals on the plates – the lead covering one cell grid and the lead oxide covering the other. When dipping them into the electrolyte bath, they release particles called electrons. When these electrons start racing the grid, they create electricity.
    While the electrons raise from the positive grid in the first cell and the negative grid, they produce 2V. The lead and the lead oxide covering the electrodes have been chemically transformed, and when the electrons from the first cell zoom into the second cell, they pick up another 2V for a total voltage of 4.
    By the time the electrons charge out of the sixth cell, they have a combined voltage of 12. That is a fully loaded battery with enough juice to power the starter and crank the engine. Once you start the motor, the fuel system takes over and keeps the motor running. The car’s alternator takes over the rest of the electrical chores. Then it is time for the battery to juice itself back up.

  • Recharging And Draining A Car Battery

    A car battery recharges by reversing the chemical reactions. Electrons coming from the car alternator now enter the battery through the negative grid of the cell and come out at the positive side. The chemicals on the grids go back to normal, and the battery is recharged and ready to put out another 12 V.
    That is unless you happen to have the car lights on overnight. In that case, the chemical reactions move in one direction, draining the battery. And this will lead to your car battery’s inability to recharge itself. The inevitable result will be a dead battery.

How to Maintain Your Vehicle’s Battery

Car Battery Buying GuideWe all take it for granted that when we turn the key in our car, it will start right away. And if your battery is weak, it is not going to start. That is why battery maintenance is too essential to your car. Since all systems in your vehicle are electronically controlled, a low battery can cause you a lot more problems than starting your car.
So it is a good idea to check your battery regularly. This is how to do it.

  • Check the battery’s terminals
    Corroded battery terminals may not provide a good connection between your battery and your car. So if you see that they are corroded, clean the terminals with a brush. You may even use a battery terminal spray to protect them from future corrosion. Make sure to apply it on both terminals.
  • Put a multimeter into use
    Electricity is invisible, so you will need a battery tester to check the voltage. Hook up your power unit and turn on the multimeter. If your car hasn’t been used for a while, your battery may only need recharging. In case you do not know how to do this, have a car mechanic test it for you.
    And if you want to find out more information about diagnostic devices, car cleaning products or any specific accessories for your car, you should definitely check what we have prepared for you in our other extensive buying guides.
  • Charging
    Car batteries are made to be charged and discharged. So if they stay unused, they go bad. And therefore, if your battery goes bad, it may ruin your alternator, so make sure you change it before that.

Charging Your Car Battery

There are a lot of reasons why you should charge your battery. Maybe your car was kept in storage for a while, you left the headlights on all night or because it just wouldn’t start. To fix this, you need to know how to use a battery charger. So, here are the main steps.

  • Hook up the terminals to your battery charger.
  • The red terminal is usually the positive, and black is negative.
  • Your charger is off at this point.
  • Ensure that you identify on your battery, which is the negative and positive terminals. Always look at the pier to check if the terminals are correct. Do not rely on colors or assumptions because car batteries differ from each other. This means that you can’t be sure unless you look at the battery box.
  • Hook up the positive to a positive and the negative to the negative terminal. Make a little twist to make sure it is a good connection.
  • Turn on your battery charger, and you are ready.

FAQ

In case you still have unanswered questions, this section is for you.

  • How do you know if you need a new car battery?
    There are a few things that you need to check. If your car cannot start or there is a slow cranking, dim lights or more than 5 years of use, then you should look for a new power unit for your car.
  • What can drain a car battery when the car is off?
    A lousy diode in your car’s alternator can cause this problem. Even when you are not using your vehicle, such diode can make the electricity flow in the circuit and hence drain the car battery.
  • How often should a car battery be replaced?
    Usually, 3 years is a reasonable period of a car battery to give you its best performance. After that, you should start looking for a new one.
