Top 5 Best Optima Battery In 2021 Reviews & Buying Guides

Before we go ahead and jump into the optima batteries review we want to basically give an idea of what we did to decide which batteries for cars are currently the best on the market. We are huge fans of the optima red top battery series, however there are tons of other car battery brands on the market that preform similar or better than the optima battery. In this review, we reviewed various brands then we composed this list of best car battery performers. Brands included in this are Kinetic, XS Power Batteries, Odyssey, and more. We did our best to get the best review so it is not too difficult for you to make a perfect decision, such that you don’t end up with something that may not work for you.

What makes Optima Batteries different?

One important thing that sticks the optima battery out from other brands is the way the battery is built and composed. The components in the optima battery are 99.9% pure lead, this purity allows optima to undergo and conduct electricity a lot faster. When electricity in a car battery flows faster you get faster recharge as well as retention of voltage. Optima red top as well as the other series have a patented spiral-cell Technology which allows the car battery to undergo harsh conditions and be vibration resistant. This is very important especially if you are in harsh environments or conditions and trying to get your car battery to start up or power up. It is also important for maintenance as vibration resistance also allows the car battery to be maintained over a long period of time. The case of the optima red top batteries have completely sealed cases which prevents any leaks and prevents contamination. Last and most importantly the optima battery series has twice the life of an average agm battery!

How do Car batteries work, Lead, AGM, And Wet-Cell?

When it comes to car batteries there are many different makes and builds of batteries. We will go through that later in the review however in general it is important for you as the savy auto guru to know how a car battery actually works. The basic function of a lead acid battery is when lead plates inside the battery react with the acid or the electrolyte. This converts chemical energy into electrical energy. Now when it comes to the modern car battery market the best builds that seem to be taking over this hundred year old lead acid build is the AGM battery.

The Agm battery :

The Agm battery or the absorbed glass matt battery is a newer and more innovative way of how batteries produce energy. This design allows the electrolyte to suspend and be in very close relation to the plates active material. Agm batteries tend to cost twice as much more than the wet cell batteries we described below, however they are more safer to use, last longer, and more than usual are maintenance free.

When it comes to versatility and longevity it is no secret AGM batteries are the way to go and will provide you with much more bang for your buck as opposed to a lead acid battery. However more often than not you may also have to purchase an additional charging unit for your battery if you decide to go with the agm route.

In the current and future markets we are seeing that agm batteries are starting to go on an upward trend and are becoming more popular than the gell cell or lead acid battery. This is most likely due to the fact that these batteries have a longer lifespan and usage rate than the average non agm battery. Not only that AGM batteries are known for being able to last and deal with harsh temperatures and multiple application types. What this does is it improves and upgrades the recharge and discharge efficiency. Agm batteries are implemented in several ways and some of them include:

  • High performance engine starting
  • Power sports
  • Deep cycle
  • Solar and storage battery

More than often users of agm batteries claim that it is best to make sure that agm batteries are discharged to no less than fifty percent of the discharge rate which usually allows for 300 or more cylces.

The wet cell battery are another version of the lead acid battery however is built in two different styles, primarily these two styles includes a maintenance free version and a serviceable version. They are both filled to the rim with electrolytes and are quite frankly the same.

The only problem with a wet cell battery when it comes in comparison to an AGM battery is the fact that agm batteries most likely won’t degrade or sulfate like a wet cell battery. What can happen is that in a wet cell battery there can possibly be a small hydrogen gas explosion which I am sure not many of us would every want to experience.

#4.XS Power D3400 XS Series AGM High Output Battery

XS Power D3400 XS Series Review

When it comes to high power the Xs battery preforms extremely well in this category. The design of the xs battery is a bit different from the other agm batteries as the electrolytes in the xs battery are suspended in fiberglass. This allows for additional spill and leakage prevention as well as vibration resistance like the optima red top battery series.  This is a great battery for any power hungry vehicle that has an demanding hydraulics or stereo system. The battery itself produces more than enough power, in fact more than you most likely will need.

With a CCA of 1,000 you are going to have very great performance on start up as well as in extreme weather conditions. The ultra low internal resistance is a key feature that makes the xs power d3400 stand out from others and is probably one of the reasons the battery is priced a bit on the higher range. The battery is a bit heavier than conventional car batteries weighing in at 48.8 lbs. Besides the price and the weight which are a bit higher the battery is a beast in power.

#5. Optima Batteries 8071-167 D51 YellowTop Dual Purpose Battery

Optima Batteries 8071-167 D51 YellowTop Dual Purpose Battery

When it comes to price, durability, and performance it really is quite difficult for any AGM battery to compete with the optima line. Despite the optima red top preforming extremely well we sometimes forget another major player in the game, the yellow top optima battery.

The D51 optima battery includes all the bells and jingles of the patented spiral cell design which allows for clean long lasting power, vibration resistance, and safety for your family. This yellow top battery is perfect for seasonal vehicles which you may not be using at all times due to the low self discharge rate. If you are a forgetful person and seem to always keep your car head lights on or leave the radio running, the optima yellow top d51 will not fail on you and start up your car like it had been turned off completely.

Our recommendation to anyone with an OEM battery is to replace it immediately with a d51 battery. Why is that? From the get go your going to be saving time and money maintenance. Despite using a power hungry car or leaving lights on, or doing other activities that may drain battery power the optima yellow top is able to jump into action within Milli-seconds. Despite the CCA being on the lower end which is 450 CCA the battery still preforms exceptionally well in harsh weathers. If you live in an extremely hot or cold climate you will be blasting the AC system, this is power intensive and will take away performance from the rest of the car. However with the optima yellow top D51 this will no longer be an issue.


  • Has fifteen times more vibration resistance.
  • Fast recharging and has about three hundred recharge and discharge cycles.
  • Spiral cell technology like all the other optima batteries which allows it to be ahead of the game in its class.


  • Not suitable for some cars

What to look for when buying a Car Battery?

Now that we broke down the unique attributes of optima car batteries lets look at what traits we specifically look at when purchasing a car battery. Keep in mind these are the general guidelines we follow when it comes to picking any good agm car battery, as optima is not the only batteries that we test and use. We know that with all the different kinds of batteries out there on the market finding the right kind of agm car battery is very difficult. It can get a bit confusing and sometimes not doing enough research may cause you to waste hard earned cash on a battery that may not even be compatible with your car battery.

The make of the battery: 

Among-st the market and stock cars you will come to find out the most popular kind of battery make is the wet or flooded battery model. Then there are valve regulated lead acid batteries which are made up of gel batteries. Lastly there are Absorbed glass mat batteries also known as AGM batteries. There are also other kinds of batteries like the deep-cycle battery which sometimes is combined with an AGM type battery such as some optima batteries are.

How batteries preform: 

There are some terms you need to familiarize yourself with when it comes to buying a battery. You need to specifically know the group size, reserve capacity, and cold cranking amps. Reserve capacity refers to the amount of time a car can run on a battery say if the alternator gives up o you. Cold Cranking Amps also known as CCA tells you how well a battery can preform in cold weather. And lastly group size is the size of the battery and its power terminals. You can always check with your make of car to see what kind of group size it requires.

Reserve Capacity: 

Reserve capacity is very important as it tells us the amount of time in minutes that a fully charged battery at the regulated temperature of 80 degrees Fahrenheit will discharge twenty-five amps until the battery dips below 10.5 volts.

Amp hour:

This rating is usually and most often found on deep cycle batteries with the standard ah rating being taken from twenty hours. This basically means that if a battery is rated at 100 AH, from 20 hours the battery will give you a total of one hundred amp-hours. As a result and if you do the basic elementary math you are getting about five amps an hour.

Maintenance of battery:

This is a very important aspect of any car battery when you decide to purchase a good long lasting piece of equipment. Many people browse through agm battery reviews and tend to over look this aspect without having any concern as to what it is that they are getting themselves into. The thing is no matter what you do you will have to try to maintain your battery to some extent.

Testing your battery:

Testing your battery is a great thing to do upon ordering an AGM battery. It is also recommended by experts at AutoZone  to periodically test your battery from time to time. The best way to test your car battery and to make sure it is up to performance would probably be by testing the battery voltage and specific gravity.


If you are looking for a car battery that preforms well don’t expect anything under $100 for a quality battery.

What to Consider to Buy the Best Car Battery ?

Here is what we recommend :

  • Purchase a battery with a high reserve capacity and or with an amp hour rating that is high.
  • If you are looking to operate your devices in harsh conditions and extreme loads we recommend to definitely go with an agm battery rather than a wet cell battery.
  • Try not to purchase your car batteries used or refurbished, as the fresher a battery the better it will be and the longer it will last. You can do this by checking the date of manufacturing for the battery before purchasing it and this can be made available quite often on amazon.
  • Look for battery warranties as this can not be stressed enough, simple fact is your car battery may break down and when it does there is usually no going back. Get a good battery that has full replaceable warranty. When we reviewed the best agm batteries on the market right now, we made sure to include the fact if a warranty was included or not.
  • Performance and lifespan of a battery is very important, for most of the batteries we reviewed we stated this important factor, and the higher the better.
  • When it comes to cold cranking amps and reserve capacity it depends completely on you as the user as to what you want to do with your application. For more extreme and harsh applications you are obviously going to want to have higher numbers in this area.
