​How to Buy a Car Battery

#1. Right Fit

Car batteries are generally made in different sizes to fit a specific type of vehicle. Here is a quick overview of the different car battery sizes so that you can find the right fit for your car.

• Size 24/24F: This type of size will generally fit vehicles like Nissan, Lexus, Acura, Honda, and Toyota
• Size 47 (H5): Will fit most cars like Volkswagen, Buick and Chevy
• size 48 (H6): One of the most popular types of sizes for premium cars. It will fit both European and American cars like Mercedes, BMW, Volkswagen, Audi, Buick, amongst others.
• Size 49 (H8): Mostly intended for Asian and European cars
• Size 51R: This size will fit most Japanese cars like Mazda, Honda, and Nissan
• Size 34/78: This is a large battery mostly for American cars like Chrysler, GM, and other American SUVs
• Size 35: Intended for the Japanese market and will fit cars like Toyota, Nissan, Subaru, and Honda
• Size 65: This is a big size car battery for North America. It will generally fit very large cars, RVs, and trucks from various American constructors
• Size 75: A car battery size that was originally made by GM. It will fit a few Chrysler vehicles as well as a few compact vehicles by General Motors.

#2. Lead-acid or AGM Battery

Often times, choosing between lead-acid and AGM battery is a question of price.

Indeed, the lead-acid battery is significantly less expensive than the AGM battery. For casual and general-purpose use, as in simply starting a vehicle, the lead-acid battery is more than enough.

On the other hand, if you need a heavy-duty battery to power demanding electric components in vehicles, then AGM was originally designed for that. Indeed, this is a heavy-duty battery that is able to send a lot of current for an extended period of time without suffering from drainage.

Additionally, AGM is more resistant to vibrations and shocks because the electrodes are made from a sheet of fiberglass that is very close together which eliminates movement inside the battery. Moreover, AGM batteries have a longer lifespan as it is made from components that do not get damaged easily.

Therefore, if you have a short budget, then you can go with a lead-acid battery for basic car needs like car ignition. However, if you need more juice in your battery, the AGM is the way to go. 

#3. Power Requirement

The power requirement is related to the capacity of the car battery. Logically, the more electric devices like headlights, music system and other you have installed in your car, the more powerful and high-capacity your car battery needs to be.

This is because, at startup, a high-capacity battery will be able to send a high current with a high amperage to your power all your various components without running the risk of them at a low startup voltage.

Therefore, if you have many components installed in your car then it is best to go with a high-capacity car battery of at least 40 AH or more. On the other hand, if you have basic electric devices installed, then you can safely go with a lower capacity 28 AH car battery and save some money as they are generally cheaper than a high-capacity one.

#4. Cold Cranking Amps

Basically, the cold cranking amps is an industry standard for measuring the current flow in a car battery at very low temperatures. The higher the CCA value of the car battery, the more you will be able to use it under optimal conditions in low temperatures.

So, if you usually use your car in very low temperatures then it is best to go with a car battery that has a high CCA value of at least 300 CCA or more.

#5. Reserve Capacity

The reserve capacity is how long the car battery is able to send a high amperage current defined by the manufacturer before it drains below 80% capacity. Of course, the higher the reserve capacity, the more heavy-duty and long-lasting the car battery usually is. In most cases, you should be fine with a car battery that has a reserve capacity of 40 minutes or more.

However, for heavy-duty purposes where you need a very high current flow in your car then it is best to go with a model that has a reserve capacity of 100 minutes or more. This is to ensure that your car battery is reliable enough in providing such a high current flow.

#6. Brand

When purchasing a car battery, you do not want to go with a no-name brand. This is because you want to ensure that the car battery you buy is made from high-quality components that you will only get when going with a trusted brand.

Brands like Optima, Odyssey, ACDelco, Yuasa, amongst others, are trusted car battery makers which make some of the best car batteries on the market. You cannot go wrong with any of them.

#7. Freshness

Sometimes, you may be tempted to buy a second-hand battery and save some money in the process.

However, this is a bad idea because the electrodes and electrolyte in a used car battery are usually in bad condition and will cause the car battery to underperform.

Therefore, it is always best to go with a new car battery even if it costs more as new batteries are almost always more reliable than old ones.

#8. Warranty

It is almost impossible for the average person to repair a car battery. So, it is important that you choose a model that comes with a warranty. Keep an eye out for a car battery warranty period of at least 2 years to be on the safe side.

#9. Price

The price of the car battery can quickly get out of hand, especially if you choose a high-capacity and heavy-duty car battery like AGM.

We recommend that you set a budget before purchasing your car battery and stick to that budget. In most cases, a high-quality car battery should cost you anywhere from $100 to $300 depending on its capacity, brand and technology used.

When to Change Car Battery 

As every component in your car, your car battery will not last forever and will require frequent changes. Each battery has its own specification and will depend on both the amount of time the battery has been used as well as the rated manufacturer spec of the battery.

As a rule of thumb, you will need to change your car battery every 3 to 5 years. Of course, some car batteries have a longer lifespan and a few reputable manufacturers claim that the car battery can last up to 10 years.

#1. Using a multimeter

However, there is another neat way to know if you need a battery replacement or not. It’s by using a multimeter. A car battery in good condition should test around 12.6V when the engine is off. If you note a voltage below 12.6V, then your car battery either needs to be recharged or replaced altogether.

Additionally, the voltage should be 13.7 V to 14.7 when the engine is on. The voltage is higher when the engine is powered on because the alternator is now charging the car battery.

#2. Maintenance-free Batteries 

Some batteries are labeled as maintenance-free. What this means is that you do not have to perform maintenance on the battery and they usually have a sealed casing which means that you will not be able to open the battery without breaking it.

However, if you are using wet cell batteries, then it uses distilled water as the electrolyte. Wet cell batteries normally have open caps so you can open the battery, remove the electrolyte and then replace it with distilled water. It is recommended to replace the electrolyte every 3 months or so when it comes to the wet cell battery.

Additionally, wet cell batteries also have an indicator at the top that will show you when it needs maintenance.

Conclusion

As we have seen, the car battery is responsible for starting your car ignition system and helps to power your various aftermarket lights, electronics and electrical devices that you install in your car. Therefore, the more equipment you install, the more powerful and reliable your car battery must be to cope with your vehicle’s electric needs.

Additionally, we have seen that there is a wide range of car batteries intended for different usages and budgets. Nevertheless, you can still get a high-quality car battery that will last you for years without spending a fortune.
