I understand that the table above has given you some ideas of what every battery involves. But that’s not enough and that’s why I have reviewed these car batteries in details below.
Why Do You Need a 12V Battery?
While there are a variety of potential uses for a 12-volt battery, the vast majority of those purchased are for use in vehicle engines. Most road vehicles use a 12-volt battery. This includes common vehicles like cars, trucks, and SUVs, along with smaller vehicles like motorcycles and even vehicles as large as RVs.
Most 12-volt battery purchases are replacements for dead batteries in cars and trucks. Even in ideal conditions, the maximum lifespan of a battery is much less than that of a modern car.
There are other reasons you might want to buy a new 12V battery, too. The most common include:
- More power. If your current battery is struggling to run all of your vehicle’s electronic components, you’ll be better off using one with a larger capacity.
- Better cold weather performance. It’s harder to start a car in cold weather. Upgrading to a battery with more cold cranking amps gives you more reliable starts when temperatures drop below freezing.
- Longer shelf life. While it’s a good idea to keep any car battery at full charge, some hold their charge better in storage than others. A battery with a low self-discharge rate will be more reliable for occasional drivers, holding the charge better when the car isn’t in use.
- Safety. Battery acid is highly corrosive. Fully-sealed batteries are leak-proof and can be installed in any position without the risk of chemical burns.
What to Look For in a 12V Battery
The first thing you need to pay attention to is the size and fit. Don’t assume that any battery you see will fit inside your engine. While most 12-volt batteries are roughly the same size, some manufacturers use a smaller battery than others.
Your vehicle’s repair manual is the best place to find out what size of battery you need. If that’s not an option, check the dimensions of the current battery and find a replacement that matches it.
Next, think about how the vehicle will be used. Do you mostly drive on city or suburban roads, or do you do a lot of off-roading? The vibration from rough roads can damage some batteries, which makes durability more of a concern for rural drivers.
Also consider how often you drive the vehicle. If the car will regularly be sitting unused for multiple days a time, a battery with a low self-discharge rate will hold its charge better when the car isn’t in use.
Capacity and Power: Do You Need the Best Performance?
Most compact cars require about 400-600 amps to start. Larger SUVs or trucks might need up to 1,000 amps, but for the most part you don’t need a super-sized battery just to start your car. Having extra power won’t cause any damage to your engine, but it doesn’t necessarily help, either. If you’re only concerned with starting your car, you don’t need a large battery capacity.
It used to be that the battery in a car was only there to start it. Now, though, more and more vehicles use electronic components that also require power. This isn’t a huge concern when your car is running but things like the radio, GPS, or other electronics can put a serious strain on the battery if you use them when the engine is off. Because of this, you may want to get a higher-capacity battery for vehicles with a lot of electronic extras.
Where you live is a factor in this decision, too. The colder your car’s engine is, the harder it will be to start. People who live in cold climates will need a battery with more starting power than those who live in places where it’s warm year-round.
Durability and Lifespan: What Should You Expect?
On average, a 12 volt car battery lasts 5-7 years. In ideal conditions that can be stretched up to 10 years or more. Conversely, especially harsh conditions can cause a battery to die in as little as 2-3 years.
Construction quality is one factor in the lifespan of the battery. A more secure, durable housing will resist damage and wear, avoiding catastrophic failures, while better internal construction quality allows the battery to survive more recharges and limits the impact of deep discharges.
A lot of a battery’s lifespan is determined by what happens to it after it leaves the factory, though. Vibration, extreme temperatures, and deep discharges all reduce a battery’s useful life. While there’s not much you can do about the weather, you can protect your battery by keeping it fully charged as much as possible.

The Bottom Line
There isn’t one 12-volt battery that’s the best choice for every driver and vehicle. Start your search by figuring out what your engine needs in terms of fit and power. From there, it’s a matter of analyzing your driving habits and environment. Cold weather, rough roads, and in-car electronics are all factors to consider when shopping for a battery.
Whichever model you buy, these 10 12V batteries are among the best on the market in 2020. We hope this buying guide has helped you pick out the right one for you!
How much does a car battery cost?
You’ll find a wide price range represented when you’re shopping for 12-volt batteries. They can run anywhere from around $75 on the low end, to upwards of $1,500 for specialty models. The biggest factor in the price is the cranking power and capacity of the battery. If your engine is larger and more powerful, it’s likely you’ll spend more for a battery to start it.
Can my car battery charge another battery by itself?
Not effectively, no. Car batteries don’t put out enough volts to effectively re-charge another car battery. The most efficient way to recharge a car battery is allowing your engine to run, which will restore the charge in the battery through the alternator. For charging outside an engine, an external battery charger or battery maintainer is your best bet.
How long does it take to recharge a car battery?
That depends on the battery and the rate of charge. Using the alternator in your car’s engine can charge a battery in as little as 30-60 minutes. With an external charger, you should expect to charge it between 4 and 6 hours, depending on the size of the battery and how deeply it was discharged.
How can you tell when it’s time to replace a car battery?
The most obvious sign is if your car won’t start or hesitates to start. While this can also be caused by issues with the starter, in the majority of cases the battery is to blame.
Electrical issues are another common indicator that your battery is dying. If the interior lights or headlights are dimmer than usual, especially right after you start the car, this could be a sign your battery is dying. You may also notice sluggishness from other electronics, like window controls, or experience a loss of power to peripherals you have plugged into your car’s charging ports.
Finally, you should replace your battery if you notice any damage to the exterior. This includes leaks, punctures, cracks, or swelling in the battery case. Batteries with this kind of damage are a safety hazard and can even catch fire or explode if the problem isn’t addressed. You should replace the battery immediately if you see any of these signs.
Can a damaged battery be repaired?
When it comes to external damage, no. Once the integrity of the housing is compromised, replacing the battery is your only option.
Damage to the plates from deep discharges can sometimes be reversed. Some battery chargers come with recovery programs that can return even completely dead batteries nearly to their full original capacity.
Keep in mind that, even with these programs, no battery is going to last forever. If your battery is 6 years old or older, buying a new battery is likely more cost-effective than getting a battery charger to restore the old one.
What is the difference between an AGM and a lead-acid battery?
An AGM battery is a type of lead-acid battery, and both styles store and release energy in a similar way. In a traditional lead-acid battery, metal plates interact with battery acid when a charge goes through them, releasing energy in the process.
The same basic thing happens in an AGM battery but the process is more refined. AGM stands for “absorbed glass mat”, referring to the glass separators between the plates found in this style of battery. These mats are saturated with an electrolyte gel that interacts with the plates in the same way as the acid in traditional lead-acid batteries.
AGM batteries are maintenance-free and spill-proof, which are the primary advantages. While they have a longer lifespan on average, they’re also more sensitive to deep discharges, and are most reliable when kept at 50% capacity or higher.
Do you have to charge the battery before installing it?
Most 12V batteries ship with at least enough charge to start your car, so you shouldn’t need to charge them before installing them. Having said that, it’s a good idea to let your engine run for at least 30 minutes the first time you start it using the new battery. This will give the alternator time to fill the battery completely in case it lost some of its charge during storage or shipping.
What charge should a 12V battery register?
The name “12-volt battery” is a bit confusing when it comes to reading the capacity. When fully charged, a 12V battery should measure at least 12.6 volts when at rest, and between 13.7 and 14.7 volts when the engine is running. A half-charged battery will read around 12.4 volts at rest. By the time the battery reads at 12 volts exactly it’s already functionally dead and will not start a vehicle.
