Best Battery for Diesel Trucks in 2020 Reviews

A diesel engine is likely to consume more power than a smaller car engine. Hence the best battery for diesel truck may not be the same battery as your sedan.  Understanding the proper requirements for your vehicle is of primary importance if you want a smooth and hassle free experience.

Since diesel engines and petrol engines are quite different, the batteries required to operate with them are also very different. This guide will help you find the best battery for your diesel truck in 2020.

What is the difference between a car battery and a truck battery?

You may think that a truck battery is just a bigger car battery, right? Well, you wouldn’t be entirely wrong. In reality, a diesel engine is much harder to start than a gasoline engine you may have in your car. The reason is that the compression capacity is way higher in diesel engines. 

As a result, a lot of electrical power is required for cranking. Some diesel trucks even use two batteries for that reason. Diesel engines usually have a stage even before starting when the combustion chamber is preheated electrically for faster cranking. Cold weathers make it even harder to start diesel engines. ‘

That is why, batteries performing in cold conditions need even more cranking power to bridge the gap. 

Other than power, trucks such as Ford F150 require batteries that are also generally tougher when it comes to durability and vibration resistance as they are more likely to be used in rough terrains.

Truck batteries also need a fair amount of deep cycling capacity to power the stronger lights or other electronics they may have.

On a general note, it can be said that a truck battery can be sufficient for a car but the vice versa is not true.

This is why it is even harder to make a proper choice. But whatever may be your requirement, this guide will help you find the optimal battery for your truck.

How to choose the best battery for diesel truck?

Just like any other product, before buying a battery, you must know about a lot of details regarding the battery so that you can get a battery perfect for your needs. Batteries come with various features and certain models have their own advantages and disadvantages. Keep in mind the following features before you buy your next battery.

Reserve capacity

In simple terms, the reserve capacity of your battery is the number of minutes your battery can supply a standard current without needing recharging.

Diesel engines are a lot harder to crank than regular gasoline engines and hence it is a good idea to look at the reserve capacity of a battery before buying. A Higher RC will make sure your battery does not fail you under harsh circumstances. Chances are, a battery with low cranking power and high RC will perform better than if the conditions are reversed. 

Warranty

Batteries work on volatile chemical principles. Even if the battery you are buying has excellent user reviews, there still is a chance that your battery might be faulty. Most good brands offer a warranty on their batteries. It is always a good idea to have a warranty on the battery you are buying as it keeps your money safe in case something goes wrong.

Size

Size turns out to be an important element too. Not all trucks have the same specifications and the battery you buy may not be compatible for your truck. Make sure you double check the compatibility of the battery before you invest in anything.

Maintenance

Some battery types are maintenance free, like the AGM type or the Gel type batteries. Maintenance free batteries are a good investment as maintenance for batteries can be a real hassle. Maintenance free batteries do not need water refilling and are fundamentally spill-proof.

Restorable

Almost all the batteries are repairable/ restorable provided correct steps are taken for the same. Battery restoration is an effective way to save some bucks but a small percentage of batteries don’t fall under that category.

Sealed Or Unsealed

This property depends on the battery type too. Sealed batteries are generally maintenance free and can be mounted in any position without having to worry about spillage. It is always a good investment to get sealed batteries.

CCA

CCA or Cold Cranking Amps is the measure of the cranking power of your battery. Diesel engines usually need higher power to crank and hence you should always look for a battery with a good cranking power. Especially, if you live in an area with cold weather, it becomes even more important for you to look for high CCA in your battery as cranking becomes harder when it’s cold outside.

Types of Diesel Truck Batteries

Diesel truck batteries, just like other batteries can be divided into a few types based on the technology they use. The common ones are, Lead Acid, AGM, Gel and so on.

AGM Batteries: AGM technology is the most popular as they provide a maintenance free design with good performance at reasonable prices.

Gel Batteries: Gel based batteries are sort of more expensive and hence not that popular.

Lead Acid Batteries: Lead Acid batteries have to be the cheapest but some of them are not sealed and hence a lot of maintenance is required to keep them in perfect shape. 

How to use a battery in a diesel truck?

Most diesel trucks use two batteries as diesel engines require additional cranking power. The combustion chamber is preheated in some models to aid combustion. This preheating is done from the power from the battery and hence a lot of power is required. Usually, some deep cycle functionality is required as well as powerful cranking. Hence most trucks use a dual battery system to take care of everything.

While this is all well and good, here are some points to ease your life. You’re welcome. 

  • If your battery is not of the sealed type and requires you to constantly refill the water, make sure to keep the battery filled as lower water levels will affect battery life. Just remove the caps and take a peek. Refill if you see fit.
  • Try not to use the battery unnecessarily Use the ignition set whenever you feel like using electronics.
  • Regularly check your battery condition. Optimally, batteries have a definite charge level when fully charged. If you see your battery falling below the desired level, consider consulting a mechanic.

How to clean a diesel truck battery?

While some batteries may claim to be maintenance free, it is always a good idea to keep you battery clean as the terminals are prone to corrosion. Corroded terminals affect the overall performance of the battery and also its battery life.

You can take care of your diesel truck battery in two simple steps:

  • Cleaning the terminals: Cleaning the terminals is easy. If you see even a bit of corrosion on your battery terminals, just remove the battery and lean the terminals with baking soda solution. If there’s too heavy corrosion, use a sandpaper or similar material to rub it off. Do this regularly and do not let corrosion build up and your battery will be fine.
  • Cleaning the battery: Other corroded regions on your battery, if any, can be cleaned in the same process. It is recommended to try to keep your battery dust-free as dust will attract corrosion in presence of moisture.

Keeping the car battery clean and tidy is not really a great or troublesome task. Little efforts can yield really good results when it comes to maintenance. 

Best Diesel Truck Battery FAQ’s

  1. Can a diesel truck run on one battery?

    Yes, a diesel truck can be made to run on one battery However, that battery has to be immensely powerful to be able to handle the load of the entire cranking process as well as the preheating and running the electronics, which is a pretty heavy task.

  2. How long should a diesel truck battery last?

    There is no specific answer for this as this will depend on how you use your battery. Usually batteries that recharge fast and discharge slow are preferred.

  3. What are the best batteries for a f250 diesel?

    There are a lot of good batteries and opinions vary but we think the Optima RedTop batteries are a good bet. Other than that, if you really want something high end, the best option will be  the XS Power D3400 XS Series 12V 3,300 Amp AGM High Output Battery. However other factors such as weather and terrain will also be a deciding factor but these batteries will perform well under unfavourable conditions too.

  4. Why does a diesel truck have 2 batteries?

    Diesel trucks have demanding engines that require a lot of power. Hence two batteries are used so they can share the load. You can pair up a deep cycle battery with a cranking battery so you can use one to start your car and the other to perform other tasks.

  5. How many CCA do I need for diesel?

    There is no specific answer but for diesel trucks, anywhere between 700-900 CCA is a safe range. Although, if you need a battery for cold weather, higher CCA is required to counteract the unfavourable weather questions. The diesel engine is pretty hard to crank as it is and the cold just adds more pressure on the battery.

Final Words

Although the XS Power D3400 XS Series 12V 3,300 Amp AGM High Output Battery seems like a clear winner it must be noted that it is quite pricey and may be an overkill for most users. Having said that, it is important to note the requirement of your truck before deciding on a battery. Different batteries have different perks and you need to choose which one suits you the best.
