What optima battery fits my car?

You may get confused about what optima battery fits your car properly? Well, if you don’t have the necessary aftermarket accessories for your car, we highly recommend the Redtop 35.

Meanwhile, if you got these types of electrical accessories like an audio system along with amps, we suggest yellow series d35. Eventually, both of these batteries are top-grade quality.

Do optima batteries go bad?

Had a bad experience with the AGM cell and its charger? Well, in most of the cases optima batteries are assumed to be bad as it needs a proper charge.

Eventually, all AGM batteries including optima batteries may stop working. Meanwhile, failures are caused when these starting batteries are used in various applications. However, the thing we like most about optima red top and the yellow top is its low internal resistance.

An AGM cell with low internal resistance might stump car guys as it doesn’t normally work like a regular flooded lead-acid battery.

The benefit of Buying the Product

Optima has a great reputation for manufacturing cells from 1990. They have already provided more than 100 million cells in the market. This reputation continues in today’s market. If you want an automotive battery of your needs, you can get easily choose one of the above which fits your vehicle best.

If you have a light vehicle like cars, you can choose one of the Red Top batteries. But for your bigger vehicles, the Blue Top model would be perfect. The Blue Top model is specially designed for high cranking and Deep sea marine use. Most importantly, it is heavier and more powerful than other batteries.

Optima use Spiral Cell Technology to build their product. This technology comes with a series of individual spiral-wound. This is comprised of two pure lead plates. These precision-controlled expensive batteries are far more effective than normal batteries. So if you are thinking of a battery for automotive needs, I will surely recommend Optima products.

Technology and Advantages of Optima Batteries

Starting, Lighting, and Ignition (SLI)

As the name suggests, the technology is all about the quick and high voltage of current.

So, to start your cars, the SLI batteries excel. But these batteries are light cycle batteries, so they are suitable for the higher current supply for the short periods.

But when it comes to providing a constant current for more extended hours, they fail miserably. That’s where the Optima deep cycle batteries excel.

The higher CCA Optima batteries can not only provide the quick start quality of the SLI, but their deep cycle feature lets you do much more.

From running the trolling motors, electric wheelchairs to powering up an entire RV, they can do it all.

So, you might be happy with the short burst of power from the SLI batteries for a quick start. But when you’re looking to enjoy all the electrical equipment in the car, you would glad to have the Optima than the SLI.

Lead Acid:

Now, the lead-acid batteries have their advantage. For starters, they are quite cost-effective in so many ways.

They do last longer than your traditional batteries. And they don’t require maintenance. So, already you have a good reason to pick it over the other.

But the best thing about it is power drainage. I’ve got to say, unlike the regular batteries, the discharge rate of the lead-acid is uniquely on the lower side.

So, it gives you extra hours. Also, they recharge fast. Slow-discharge and fast charging, now that’s like the best combo you can get with a battery ever.

Deep Cycle

So, deep cycle batteries are superb when it comes to churning out power for more extended periods, that you know already.

But deep cycle batteries have many other benefits like extended durability. That’s always a significant issue with most batteries as they don’t last long. Especially in the hot temperature, the SLI batteries give up due to the heat and start to fail. However, deep cycle batteries don’t get affected by the heat. That’s because it can handle deep discharge. Something the standard batteries fail miserably to do.

Plus, for long-term storage, they are better options because they have a slow self-discharge rate. The numbers can be around as low as 3% per month. Now, that’s in itself is impressive.

Wet cell:

The wet cell battery, or widely known as the flooded, is the original rechargeable batteries. They are the earlier version of the lead-acid battery. Now, Optima is an AGM battery, which is the latest kind of lead-acid battery out there.

They don’t store as good as the Optima, nor do they have a low discharge rate.

However, some people still favor the wet cell due to its one essential quality, which is its charging ease.

As you know, you’ve got to be particular with the charging of an AGM. Flooded batteries don’t have the overcharging issue, nor do they get wrecked if you don’t regularly charge them appropriately. So, that regard, they’ve got the upper hand on the AGM. But they do still lack the quality of the AGM in all other departments.


The Optima batteries are highly reliable. They have low discharge; they don’t get affected by the heat, nor do they require any maintenance.

That tells a lot about its reliability.

But when it comes to resistance to vibrations, they blow their competition out of the water. The AGM batteries are a beast in this regard. No matter how much it vibrates, how hard the road gets, your cells don’t feel the slightest bit of it due to its sturdy build.

So, take on the rocky roads without hesitation with Optima under the hood.

Sizing up the Battery

Sizing the battery depends on a couple of factors. For starters, the size itself. How big or small the battery needs to be depending on the car.

The next thing is power. If you’re opting for higher amps, then you’re most probably would buy a bulky battery.

So, depending on these factors, your battery size will be chosen.

Cranking Amps

Now, this is measuring system manufacturers use to rate output. So, cranking amps means how long the battery outputs the power.

For a lead-acid battery, the number is 32°F.

The cold-cranking amps determine how much amps the battery can deliver for how long without dropping the volts. So, the higher the CCA, the better chance you’ve got of starting your car in cold weather.

Battery essentials (cranking amps, cold-cranking amps & Reserve capacity)

Now, this is measuring system manufacturers use to rate output. So, cranking amps means how long the battery outputs the power.

For a lead-acid battery, the number is 32°F.

The cold-cranking amps determine how much amps the battery can deliver for how long without dropping the volts. So, the higher the CCA, the better chance you’ve got of starting your car in cold weather.

Reserve capacity, on the other hand, tells you the discharge rate. It shows how long a fully-charged battery can deliver 25 amps of current at a temperature of 80°F-environment. And that’s even before the battery gets discharged down to 10.5 volts.

And like CCA, the higher RC rating is always better.

How do you choose the Right Battery for Your Car?

Now, this one varies from person to person. Not everyone has the same needs, and not everyone has the same amount of money to spend. However, keeping the basics in mind, let’s get into the fact about the things you need to consider while finding the right car battery.

Size: Don’t go overboard with the car battery. It won’t do good if you can’t fit in under the hood.

So, the first rule of thumb is to get a car battery that fits the car.

Now, Optima AGM’s are compatible with most vehicles. But depending on the power your car needs to have, the sizes of the batteries might vary a bit.

So, make sure you have got the size right before heading with the purchase.


Knowing the essential numbers of the battery is the key. And you might already know what I’m talking about here.

Yes, the CA, CCA, and RV of the battery.

These are the things that make the battery worth to buy or not. So, get your numbers right while buying the car battery.

If you need to store a bit of power, then a higher reserve capacity battery would come handy. The same way, an Optima battery with a higher CCA rating would be your savior on the chilliest of nights.

But if you live in a hot climate or don’t require to store the amperage, you can use lower-rated batteries. Simply get the numbers figured, and you will get the right battery.


One of the issues with regular batteries is that they require maintenance. Otherwise, they get wrecked.

Now, AGM batteries like Optima require almost no maintenance whatsoever. So, if you’re down with it, you are one step closer to the car’s right battery.


The performance of the battery matters the most. But you don’t want to buy a battery that needs to be replaced every two months. No matter how great it performs, the short lifespan is a drag.

The right battery is the one that would last years. AGM batteries have a better lifespan than their counterparts. So, if you’re looking for a long time companion for the car, then go with a battery that would last long like AGM.

Optima Battery Charging & Maintenance

One of the benefits of having lead-acid batteries such as the Optima Blue Tops is that they retain the charge better than your regular ones.

Yes, like traditional batteries, they also do self-discharge.
