Looking for the best battery for your 6.7L Cummins engine is a smart decision if you want to keep the engine working for a long time. It is always advisable to check the specifications and features of the batteries you plan to buy, as they vary from brand to brand.
There are various types of batteries available in the market. Some are Ni-MH, Ni-Cd, Li-ion, Li-polymer, and Lithium-ion.
Li-ion batteries are the most commonly used because of their high energy density and long life. However, they are expensive and require charging every three months or so.
Ni-Cd batteries are cheaper than Li-ion batteries and last longer, but they are prone to damage due to their chemical reactions. Li-polymer batteries are better than Li-ion batteries as they are safer to use, but they are more expensive than Li-ion batteries.

1. Odyssey Battery 94R-850 Lead-Acid Battery
Best PickWe’re using this battery to power the car charger, but it would work equally well for anything else you need to power regularly.
We’re using a 2A charger, which is a little over half the capacity of our original battery. It works well because we can get a full charge in four to six hours. There are two reasons why using a lower-capacity charger is better.
First, it means you can fit the battery in a larger space. That’s useful because the battery is very heavy, and you want to ensure it’s positioned in the right spot.
Second, it gives you a lot more time to charge the battery before it needs to be replaced. The higher capacity chargers meant we couldn’t fully charge the battery for over two years. This is because we needed to charge it fully daily, and we could only do that in the morning and evening.
Now, we can charge the battery for around 6 hours, which will last a year. The battery also has a lifetime warranty and will be replaced free of charge.
I’ve never had a problem with Odyssey batteries, and the customer service is great. It’s nice that they offer a free replacement when the battery gets damaged.
Pros
- Ultra-high capacity
- Built for extreme performance
- Extremely reliable
- Sturdy and durable
Cons
- Not suitable for the following applications:
- Airplanes, boats, heavy machinery, motorcycles, snowmobiles, or cars

Thing To Consider Before Buying the Best Battery For 6.7L Cummins.
You’ve been planning to purchase a battery for your vehicle, but have you ever thought about how much battery capacity you need? Most people use their batteries, even when not running the engine. While this can be helpful, it can drain the battery quickly if you’re not charging it frequently.
What does that mean for you? It means you must ensure you’re getting the most out of your battery to get the most miles per gallon while driving.
Learning about the battery’s capacity is good, which tells you how many miles you can get from a full charge. It’s not just a single number but also a percentage based on how full your battery is when it’s fully charged.
Best Battery For 6.7L Cummins
It’s important to understand that capacity is one of many factors in determining the distance you can drive on a single charge. You also need to consider the battery’s state of charge, the number of cycles the battery has, and how fast the battery is drained, among other things.
For example, if you’re looking for a 12v battery, and it’s only rated at 80% capacity, that means you can get 80% of the battery’s capacity or 8 hours of driving.
Now, if you were looking for a 10.8v battery rated at 90% capacity, you can get about 9 hours of driving, and if you were looking for a 14.8v battery rated at 95%, you could get about 14 hours of driving.
The battery’s capacity is the most important factor to consider, but there are other factors to consider as well.
Battery State Of Charge
As you may know, the battery’s capacity changes as it drains. As the battery lowers capacity, you’ll get less distance and power until you reach 0% capacity.
This is why it’s important to know how many cycles the battery has. If you have a newer car than 2010, the battery may have already gone through its life cycle, meaning you should expect a lower distance and power when fully drained.
Cycles
A battery’s capacity may change over time, referred to as cycles. It will gradually lose its ability to hold a charge and must be recharged.
If you’re not planning on keeping the battery in your vehicle for a long time, you don’t need to worry about the number of cycles. A battery that has never had any cycles is perfectly fine as long as you understand its capabilities.
However, if you plan on keeping the battery in the vehicle for a long time, you must ensure you’re getting the most mileage. You can extend the battery’s life by recharging the battery.
If you keep the battery in your vehicle for a long time, it’s a good idea to look for a battery that’s been through the most cycles possible. The more cycles the battery has gone through, the less likely it is to die in the future.
Drain Rate
Another important factor to consider is the drain rate of the battery. As you may know, a car’s engine is powered by electricity, so it needs a steady flow of electricity to run properly.
When the battery gets low, the engine may stop running entirely, so it’s important to know how fast the battery drains.
A battery with a high drain rate means you’ll have to recharge it often. A high drain rate can also cause the battery to become weak and prone to damage.It’s important to note that there are two different drain rates.
The drain rate is the total amount of electricity drained from the battery per hour.The second drain rate is the total energy drained from the battery per hour.
Both of these rates are measured in amps.
Battery Size
There are two different sizes of batteries to consider: 12v and 24v.
12v batteries are used to start cars and in some small engines and lawnmowers. The size of the battery you need depends on the size of the vehicle you own.
24v batteries are used for larger vehicles like trucks, SUVs, and RVs and are often installed on golf carts. You’ll find these batteries in vehicles like these because they’re the largest.
When purchasing a battery for your vehicle, you’ll find two different types of batteries: lead-acid and lithium-ion.
