Top 5 Best Deep Cycle Batteries 2020

Whether you are looking to install a solar panel in your home to go off-grid or stepping up your fishing game by getting yourself a boat, sooner rather than later, you are going to require a deep cycle battery.

And unlike car batteries, many people have no understanding of deep cell batteries because they are not needed that often so if you are also one of those many people who have zero confidence while choosing a deep cycle battery for themselves.

There is no need to fret. I have cherry-picked 5 best deep cycle batteries with help from my prior experiences and reviewed them in detail.

You can read through each of the battery's reviews and figure out the one that will be the most ideal for you.

How To Pick The Best Deep Cycle Batteries For Your Needs

Before you dive deeper into the batteries' descriptive reviews, it is essential to know what features and attributes you should keep in mind when searching for a deep cycle battery in the first place.

I have also inserted some questions here that people often ask while purchasing a deep cycle battery. You can check them out too.

What to look for when choosing the best deep cycle batteries?

When buying a deep cycle battery, check the battery's capacity and always inspect whether its battery capacity will be enough to run whatever you want it to run smoothly or not. Also, see that if you are going to harness small output from the battery, there is no need to buy a large capacity battery. The high capacity batteries cost more, plus the extra energy would be of no use to you.

What brand should you go for when buying a deep cycle battery?

Some people skip this part because, to them, a low price is an utmost priority. But, I would never advise you to go for a shi*ty two-star brand to save a few extra bucks because the deep cell batteries manufactured with low build quality are not at all rugged and will hit you in the long run.

All the deep cycle batteries I have recommended in this article are from reputable manufacturers. Even if you don't find any of these batteries suitable for whatever reason, you can buy some other battery but never cut corners and go for one without researching the brand's past reputation.

What are the benefits of using a deep cycle battery?

These are the advantages of using deep cycle batteries.

  1. They are lighter and less bulky than traditional lead batteries.
  2. There are no liquids required in deep cycle batteries.
  3. Low maintenance cost.
  4. Deep cycle batteries have less energy loss.
  5. These batteries charge at a fast rate.
  6. The batteries are durable and also have a long life span.

How long does a deep cycle battery last?

Deep cycle batteries are usually pretty long-lasting. You can use a deep cycle battery for up to six years provided that you take proper care of the battery and make sure that it is not getting damaged during the charging process.

You can learn more about the maintenance structure of deep cycle batteries here.

Can you use a deep cycle battery in your car?

The clear answer to this bizarre but frequently asked question is a big NO. A deep cycle battery can not produce enough power to start up your car in the first place, and even if you manage to run your car somehow because of a small engine. You will not be able to make it far, and the battery will lose its life in a very short time, so it is not practical at all to use a deep cycle battery in your car.

At what amperage rate should I charge my deep cycle battery?

Usually, these batteries are charged at more than 6 amps. However, there is a different rating recommended for every battery, depending on its size. I would recommend you check the label on your battery to get hold of the precise ampere rating you should charge your battery and if you can not find the rating on the label, then look for it on the battery's manual.

Can you overcharge a deep cycle battery?

No matter what type of battery you are using, overcharging is never a good idea. In fact, overcharging a battery can reduce the battery's life, so a good idea would be to disconnect the battery from the source once fully charged.

What is the difference between a car battery and a deep cycle battery?

The significant difference between a traditional car battery and a deep cycle battery is that the deep cycle battery discharges very quickly. On the other hand, a car battery takes some time to discharge.

What is an AGM deep cycle battery?

Put merely, AGM batteries can handle high temperatures, and also do not discharge faster like other deep cycle batteries.

You can read more about AGM batteries here.

How to identify a bad deep cycle battery?

The best and easiest way to identify if a battery is bad or damaged is by charging it thoroughly and then using it. If the battery gives the output that is guaranteed by the manufacturer, then it means that the battery is probably fine. Otherwise, it would be best if you reconsidered buying it.

To learn more about how you can identify a bad deep cycle battery, you can check out this article in which this subject is discussed in-depth.

5 Best Deep Cycle Battery Reviews

1- WindyNation AGM Deep Cycle Battery

Windynation Agm Deep Cycle Battery

What purpose does it serve best?

This affordable battery is best for the people living on an off-grid system. If you also have one for the eco-friendly movement, you should definitely consider this battery.

People with RVs or other kinds of remote living houses can also go for this battery because of its ruggedness and reliability.

Design

I would surely not call WindyNation's design sleek. It is, in fact, a little similar to the design of a standard car battery. You can fit this battery even in a not too small but small place because of its reasonably minimal size. A carrying handle on the battery is, however, missing.

What is the best attribute?

The best attribute about this battery is the ruggedness and its consistency to charge despite the weather conditions. The batteries that I test are mostly fragile when it comes to harsh cold weather conditions and face problems in recharging. But, WindyNation has undoubtedly stood out from the charging and recharging standpoint. If you are all for fast charging, you should most definitely look into this battery. It has excellent capabilities in the charging department.

However, I would not call this an attribute, but, as I mentioned, the significance of the brand earlier in the article. It is excellent that WindyNation's brand has some good past reputation.

Final verdict

I think that this battery is a marvelous addition to solar homes, RVs, motorhomes, and other remote uses, even though the battery is in no way practical for being carried around due to its hefty weight and lack of a carrying handle. But, it is still small in size and can be placed in tight spots inside remote places.

The battery's charging capabilities are incredible, and It also comes at a bargain price, so I think it should be a go-to buy for anyone willing to use it in a remote home or for an off-grid system.

Pros

  • It can withstand harsh weather conditions.
  • Capable of recharging fast.
  • Excellent for being used in remote homes and RVs.
  • It has an affordable price tag.
  • Good brand reputation.
  • It does not take much space.

Cons

  • Not suitable for being carried around due to its heavyweight and missing carrying handle.

2- Universal 100Ah & 12V Deep Cycle Battery

Universal 100ah & 12v Deep Cycle Battery 2

What purpose does it serve best?

Like our previous contender, Universal 100Ah 12V is also great for hooking up with solar panels.

Apart from using it with solar panels, this battery is even better for part-time roadies. Its extra ruggedness gives it a bonus for being used in RVs and motor homes. Just Install this bad boy, and it will power your crib through all the rough and tough terrains and conditions.

Design

The battery is rectangular. Its body is made up of rugged material with the intention of preserving the inner matt glass. The closings of the battery seem to be very strong and will not be cracked easily.

The entire battery's entire structure weighs a hefty 60 pounds, but the small size indeed complements the use of the deep cycle battery for traveling purposes. There is also a carrying handle present at the top for anyone who wants to carry it.

What is the best attribute?

The best thing about this battery is that it is robust. You can use it without any obstructions - its maintenance cost is almost next to none because it is an AGM, and in case you do not know, AGMs do not require any special liquid or gas to run.

You can take advantage of the 100Ah of this battery. It will consistently provide you with power without causing any discomfort, no matter how bad the weather situation is.

The product is not even that expensive if you consider the quality of the materials used in making it.

Final verdict

For what this battery is worth, it is a bargain. I know many people will contradict my above statement and rant about the fact that you can buy 100Ah batteries at cheaper price points. But, the point is that the material used in Universal AGM is top-notch. Its sturdy body can hold against unfavorable conditions. The thing is a rock and will prove to be beneficial in the long run.

Apart from it being sturdy and robust, the battery's recharging potential is impressive too. You can charge it very fast.

Suppose you are looking for a rock-solid battery that can consistently supply DC power to your RV, motorhome, any other remote area without any interruption. In that case, Universal 100Ah is undoubtedly the one for you.

However, if your requirements are slightly different, you can take a step back because it might not be the perfect fit for you.

  • The battery capacity is fantastic.
  • It recharges at a fast rate.
  • The build is rugged.

3- Optima BlueTop 8016-103 D34M RV & Marine Deep Cycle battery

Optima Bluetop 8016 103 D34m Rv Marine Deep Cycle Battery

What purpose does it serve best?

The BlueTop is made for not just one, but in fact, dual purposes. Not only does it store energy like a traditional deep cycle battery, but it can also be used to start up the engine.

This latest technology provides optimal performance technology in both areas. For this reason, it can be an ideal pick for marine vessel owners.

Design

BlueTop's design is a bit unique because of the use of Spiralcell technology in it. The battery from the front looks like it has three cylindrical shaped pieces meshed into one to give structure to the battery. The top is sealed with a fixed cap. BlueTop's closings are tightly packed, and you can easily carry it around without the stress of spilling.

Its sleek design is also ideal for mounting the battery on marine vessels (boats, etc.) and RVs.

What is the best attribute?

The best attribute of BlueTop is that it can perform dual functionalities. You will not need to carry the weight of two separate batteries, one for start-up and the other for running. One less battery would take a lot of work off your hands - no need to stress about the maintenance of two batteries. I think the ability to perform two tasks from a single battery is excellent and very practical.

Aside from the fact that it can multitask, the spiral design of BlueTop gives it the advantage of bearing harsh weather - cold conditions.

The life span of these batteries is also excellent compared to traditional deep cycle batteries.

Final verdict

In my opinion, if you are a person who has some marine vessel or RV, and you do not want to go through the hassle of maintaining and carrying two different batteries, then BlueTop is the jackpot for you. It will both start up your engine and provide uninterrupted power to your crib.

However, BlueTop is not cheap. There is a price you will have to pay for the comfort you will get from it. But, if you are that person who wants to get the weight of two batteries off their chest, then I am sure you would be willing to pay the price for it.

Plus, BlueTop will also last longer than traditional deep cycle batteries, so it definitely will be an excellent investment.

Pros

  • It can be used for dual purposes.
  • The maintenance cost is almost none.
  • It works fine in harsh weather conditions.
  • Solid build quality.
