The Best Battery For 6.7 Cummins: What To Look For?

Types of Battery

Note that there are two types of batteries available for diesel engine-powered vehicles. These two main batteries are AGM and Lead-acid. Lead-acid batteries are the most common diesel pickup truck option, while AGM batteries are considered the most sustainable.

Cold Cranking Amps (CCA)

This simply refers to the total number of amps a certain battery can discharge at the rate of 7.2 amps for 30 seconds and zero degrees. Harsh cold weather is one of the causes that can make the engine start rough.

If you live in places where the temperature falls mostly below 0° F, you should go for a battery with a higher Cold Cranking Amps rate. In that case, batteries with 500 CCAs are suitable for vehicles.

Reserve Capacity

Considering 25 amps of discharge, the total battery’s runtime is known as Reserve capacity (RC). The measurement usually impacts how many accessories you can run by your vehicle or what electronics you can power before the battery lapses.

In such cases, the AGM batteries are best due to their Highest RC. Batteries with an AGM design can keep almost 80% of their charge after a strenuous discharge.

Size

There are different sizes of batteries available on the market. The physical measurements (Height, Width, and Length) make a certain battery different from others. When looking for a replacement, ensure a better size with the most suitable fit.

The Bottom Line

Essentially, your Cummings 6.7L diesel engine requires a reliable and solid battery for optimal performance. We’ve discussed the best four replacement batteries ideal for such engines. You might want to follow the guide above to make sure you get the best battery that fits your vehicle for better performance.
