How-To: Choose The Best Batteries for Your Truck

What could possibly be worse than the Monday morning commute to work?

How about when you go to start your truck one cold January morning in preparation for your drive and all you get from the truck is endless cranking or a dull click from the starter?

Of course, batteries are pushed the hardest in the winter and in our freezing conditions it was really no surprise that the fail so often in these conditions.

Unfortunately, I speak from experience, as this had actually happened to me. I hadn’t driven the truck at all that weekend, so my batteries were just done with life after sitting inactive that long in the cold.

I learned a couple of important lessons that day, number 1 being that jumper cables do you no good at all if no one is around to give you a jump, number 2 being that when 5 year rated lead acid batteries haven’t been replaced in 7 years, they’re pretty darn prone to fail at any point.

What is the best truck battery?

If you shop around in stores and online these days, you’ll find that there are more than a dozen different main battery brands. What you probably didn’t know (and neither did I) but there’s really only a few of the main manufacturers that are actually producing the batteries for all of these different brands.

In case you were wondering, the breakdown of the manufacturers of the different mainstream brands are as follows:

Johnson Controls makes Duralast (for Autozone,)  EverStart, AutoCraft (Advanced Auto’s brand) as well as Diehard and Interstate.

Exide is another of the big guys, they put out batteries under their own Exide brand, as well as under Orbital, Bosch and Marathon.

EnerSys Energy Products is the company behind the Odyssey brand batteries.

East Penn Manufacturing is well known for producing the Deka brand automotive batteries.

Which size batteries to buy?

The comparisons below focus mainly on which of the group 65 batteries are the best option, as this is the size I needed for my 6.0 powerstroke. Of course, if you are in the market for a new truck battery, you would want verify that your truck uses this size group also before buying one (a lot of diesels do).

For other trucks, check the following:

• 2000-2005 Dodge Ram w/Cummins 5.9L: Group 65   Requires 2 Batteries
• 2006-2017 Dodge Ram w/Cummins 6.7L: Group 94R    Requires 2 Batteries

• 2003-2007 Ford Powerstroke 6.0L: Group 65    Requires 2 Batteries
• 2008-2014 Ford Powerstroke 6.4L: Group 65    Requires 2 Batteries
• 2015-2017 Ford Powerstroke 6.7L: Group 65    Requires 2 Batteries    

• 2008-2010 Chevy Duramax LMM: Group 48    Requires 2 Batteries
• 2011-2016 Chevy Duramax LML: Group 48     Requires 2 Batteries

Take note:  If your truck uses two batteries, it is best to have a matching set, as it will extend the overall life of your truck’s electrical system. Always replace in pairs for a dual battery setup.

• Odyssey 65-PC1750T Automotive and LTV Battery

Odyssey has been making the best batteries around for quite awhile now, and while they are definitely not the cheapest option, they are virtually unbeatable in terms of quality.  This monster in particular provides 950 CCA (cold cranking amps) which would be enough power to start the most stubborn of trucks, even in extreme weather conditions. The sealed AGM (absorbed glass mat) design of the battery will hold up to almost all conditions that you can throw its way, from vibration to very cold and very hot temperatures no problem.

Product Description

ODYSSEY Batteries Automotive and LTV Battery delivers the massive starting power, rapid recovery and amazing deep cycling capability that vehicle demand. Whether for everyday or emergency use, vehicles are loaded with more electronics than would have been imaginable just a few years ago. And hobbyist vehicles now include more specialties and specialized power demands than ever before. Fortunately, the ODYSSEY battery has been designed to keep up with the changes. Because its plates are made of pure virgin lead (unlike the lead alloy in most batteries), ODYSSEY packs more plates in. More plates mean more plate surface area, and much more power. Twice the overall power and three times the life of conventional batteries, up to 400 cycles at 80 percentage depth of discharge. These batteries are built for a range of performance from everyday vehicles, classic and antique cars, high performance cars, 4x4 and Off-Road, to modified vehicles. Its construction consists of pure virgin lead plates for maximum surface area and optimized recycling, AGM (absorbed glass mat) design that eliminates acid spills, high conductivity, corrosion-resistant tin-plated brass terminals, high integrity terminal seal, a sealed design resulting in gases recycled internally, a self-regulating relief valve, tough flame retardant cell containers and robust internal cell connections to prevent vibration damage. ODYSSEY batteries beat spiral-wound. Compared to spiral-wound batteries of equal size, ODYSSEY batteries pack 15 percentage more plate surface area into the case. Avoiding the dead space between cylinders in six-pack designs means ODYSSEY batteries deliver more power and 40 percentage more reserve capacity.

• Deka Intimidator Extended Life AGM Battery 9A65

Skip the inflation of buying a name brand, and go right to the manufacturer with these Deka batteries. These are made by East Penn Manufacturing, who have been behind the scenes of many of the most popular battery brands for decades. This model has the AGM technology along with 860 CCA at 32° F to start you up reliably, even in colder temperatures. The advantages of the AGM construction are vibration resistance (good for off-road) and longevity. The Deka brand in particular is an exceptionally good value because of the elimination of the middle man who slaps an auto parts or battery store brand on and marks up the final cost for no good reason – as they’re still an East Penn made battery.

• NORTHSTAR Pure Lead Automotive Group 65 Battery NSB-AGM65

I first thought that because of the name, this battery would be the old lead-acid style. It’s actually an AGM battery, which means it has the superior glass mat inside. It’s also made in the USA, which is good to see these days. Apparently these northstar batteries are used in a lot of custom audio cars, so that’s a good indicator of massive capacity which translates well for diesels.

Hard start issues caused by low batteries

On a diesel truck, the amperage of your batteries is of even more importance than on a gas powered vehicle. When you turn your key and engage the ecm, glow plugs, ficm, fuel pump and starter, a huge draw is put onto the batteries, and they really need to be healthy for everything to work as it should.

I’ve seen trucks before that sounded really healthy and fine when cranking over, but just seemed to not want to start. I later found that this was because the batteries were not supplying enough amperage for all of the ancillaries to do their jobs.

With this in mind, if your truck starts having issues with starting, the first thing to test would be the batteries, if they are older than their rated lifespan.

FICM Damage caused by bad batteries

Another big thing to watch out for, especially with the 6.0 powerstroke, is bad batteries taking out your FICM (Fuel Injection Control Module). A defective FICM can easily keep your truck from running correctly, or even at all, often throwing codes for all of the injectors, which is a dead giveaway.

It’s a good idea to always periodically check you batteries to make sure that they are not putting excessive load onto the charging system, which is what ends up damaging the FICM.

Read more about how to trouble shoot and repair your control module in our FICM repair guide.
