Best Battery for Diesel Truck Buying Guide & FAQ

A battery for a diesel truck is not the same as one designed for use in a gasoline-powered car. Diesel truck batteries come in a wide range of styles that can address a variety of issues. The type of battery that you select is going to be directly dependent on your truck and overall performance goals. 

Typically, these aren’t questions that you need to ask yourself until it’s time to replace the existing battery in your diesel truck. But if you feel like your current battery is limiting performance, this is also a great reason to consider upgrading to a new truck battery. 

Why You Need Batteries for Diesel Trucks

One of the biggest issues you can address with a battery for a diesel truck is to maintain performance. Opting for the wrong battery can negatively impact your truck’s performance. Common issues you might face include stalling, a complete shutdown if you leave a truck idling for too long, or even damage to your truck’s electrical system. In a worst-case scenario, whether you’re at a red light or in a parking lot, you could be stranded.

Proper winterization and preparation is another reason to pick the right battery for your diesel truck. The winter can be hard on all vehicles, including trucks. Freezing weather can prematurely drain batteries, leaving you with a truck that won’t start. In contrast to traditional batteries, diesel truck batteries are optimized to withstand extreme weather because of their cold cranking amps.

Of course, one of the most common reasons is to replace an existing battery. Lead-acid batteries are common, but they come with a shelf life of roughly seven years. But in some cases, they can age prematurely, and that means that within five years you might need to upgrade and replace your existing battery. When the time comes, opt for a premium truck battery that’s rated for performance, so you’re less likely to be stranded or find yourself replacing it as frequently. 


  • Improves truck performance.
  • Helps to winterize your truck. 
  • Lasts longer than traditional lead-acid batteries. 

Types of Batteries for Diesel Trucks

Just like anything else, there’s more than one type of battery you can choose when shopping for your diesel truck. Typically, there are two main types of diesel truck batteries—AGM and lead-acid. However, lead-acid batteries can be further divided into additional categories. Below, we outline the most common options, as well as their benefits, and a few details on their construction. 

Absorbable Gas Mat (AGM)

AGM batteries are best known for their discharge and recharge efficiency. This is because they feature an electrolyte solution that’s close to the metal plates. As compared to other battery types, they feature a slower discharge rate. AGM batteries are also more sustainable since most of the parts can be recycled. This includes plastic shell, fiberglass, and lead-acid. Compared to traditional batteries, the only waste is divider linings.


Lead-acid batteries are the most common option for diesel trucks. As the name implies, they feature a combination of lead and acid to store an electric charge. This category can be further divided into wet-cell and gel-cell lead-acid batteries. Wet-cell batteries have a sealed option that causes the battery to lose power as the electrolyte level decreases. But you can also choose to add distilled water to extend the battery life. Gel-cell batteries feature electrolytes that are suspended on a gel and are best suited for hot environments. 

What to Look for When Buying Batteries for Diesel Trucks

Now that you know the most common types of batteries that you’ll find when shopping for an upgrade or replacement, what are the core features you need to keep in mind? Top features you should prioritize include those that improve performance for routine use or in more extreme conditions like freezing or extremely hot weather. 

  • Cold Cranking Amps 

The term Cold Cranking Amps (CCA) refers to the total number of amps a battery emits at zero degrees for 30 seconds at a rate of 7.2 amps. Extreme cold is one of the key times when it can be hard to start an engine. If you live in a region where the temperature routinely drops below zero degrees Fahrenheit, look for batteries with a higher CCA rate. In this scenario, opt for batteries with over 500 Cold Cranking Amps. 

  • Reserve Capacity

The reserve capacity (RC) measures a battery’s running time with 2.5 amps of discharge. This figure will directly impact how many electronics you can simultaneously run through your truck or what equipment you can charge before your battery dies. With this feature, AGM batteries are the best option because they have the highest reserve capacity. AGM batteries can hold as much as 80 percent of their charge even after a deep discharge.

  • Size

Unsurprisingly, the type of battery you select is going to be directly impacted by the year, make, and model of your current truck. For the best fit, your new battery should be identical in size to your current OEM battery. As a matter of safety, your battery should never touch the hood of your truck. For added precaution and to prevent fires, ensure that there’s a hood clearance of at least 3.4 inches.

Tips for Buying and Using Batteries for Diesel Trucks

What are the best ways to buy a battery for a diesel truck? Are there things you can prioritize to improve installation or performance? Two major issues you need to consider are life cycle and compatibility. The life cycle refers to the total number of charges and discharges that a battery can complete before it completely loses power (dies). Even though manufacturers list the life cycle of their batteries, it’s important to note that real-world conditions and the rate of discharge can impact the true life cycle. 

Compatibility is a fairly straight-forward consideration. Always check that the battery you’re planning to purchase is designed to fit with your truck’s engine and connection terminals. This is important because a proper fit between the connection terminals means that your battery is securely in place and less likely to be knocked loose through vibrations while your truck is in motion.

  • Prioritize higher life cycles, but remember that real-world conditions and usage can impact this figure.
  • Always check for compatibility between the battery and your truck’s connection terminals. 
  • If you live in colder regions, prioritize a higher CCA rating as cold weather can prematurely drain a battery. 

Best Batteries for Diesel Trucks FAQ:

It’s understandable that you might have questions about signs that it’s time to replace a battery  or how to properly install or calibrate a new battery for your diesel truck. For example, a bad battery may take longer to start your truck’s engine or may struggle to distribute power to other areas of your vehicle. A great example is if your headlights look dimmer than usual. Also, if you’re focused on optimizing power to your diesel truck, consider installing two batteries instead of just one. While it’s possible to find an oversized battery for a diesel truck, they aren’t as common. 

If you’re not a mechanic or a gearhead, it’s easy to assume that you could use a battery from a gasoline-powered car to help jump start a diesel truck. Although it’s possible to do this, it’s usually not ideal since it can take longer to power the truck this way. And for the curious, there are deep cycle and starting batteries that are additional options you might encounter. Both of these options feature lower cranking volume and are more ideal for use with a truck that features multiple aftermarket accessories like sound systems. While these types of batteries are fine to use, you can also opt for an AGM battery for your diesel truck instead. 

Q: How do I know I have a bad battery?

Telltale signs that it’s time to replace your battery begin with a vehicle that won’t start. Additionally, you may notice that other electric-powered accessories like your headlights are dimmer.

Q: Do I need to find an oversized battery for my diesel truck?

Oversized batteries are an option, but these are typically an aftermarket replacement and can be harder to find. Instead, opt for two batteries that are hooked up with a parallel connection to maintain a constant voltage and improve the current rating.

Q: Can I use a gasoline-powered vehicle to jumpstart a diesel battery?

Yes you can, but this is not a quick fix or a long-term solution. You may find that it takes longer to accomplish if the battery level on your diesel truck is very low or dead. If you find that the diesel truck’s battery is consistently low or needs a jumpstart, it’s time to replace your battery.

Q: Should I get a deep cycle or starting battery?

Deep cycle and starting batteries have lower cranking volume. They reserve most of their energy to power aftermarket accessories and electronics, like sound systems and televisions. Although an oversized deep cycle battery can support this, you can also pick an AGM with a solid reserve capacity.
