Product Description

ionic lithium 12v group 31 | 3000 ca | lifepo4 heavy duty diesel starter battery

LiFePO4 batteries, like our 12V Group 31 Heavy Duty Diesel Starter Battery, are about 70% lighter than traditional lead-acid batteries. They’re easy to install and come sealed, eliminating concerns about electrolytes or other time-consuming issues.

In many diesel trucks, having a reliable multi-battery system is crucial for starting the engine, as the failure of one battery can affect overall performance and the ability to start. Now this 3,000 CA Group 31 Heavy Duty Diesel Battery is more than enough to start most heavy duty engines by itself.

These lithium batteries are cost-efficient, with much longer lifespans and faster charging times than traditional options. They’re ideal for tough and demanding use and provide reliable power for additional electronics. Plus, they’re non-toxic, maintenance-free, and come with Bluetooth monitoring for easy management, and this particular starter battery has a built-in heater for reliable charging and operation.

Lithium Diesel Battery w/ Built-in Heater: Longer-Lasting, Cost-Efficient

Having a starter battery with a longer life cycle is a must if cost-efficiency is important to you. These lithium starter batteries last much, much longer than lead-acid batteries. But they also charge around 5x faster. So whether you use our LiFePO4 Heavy Duty Starter Battery for your semi-truck, heavy duty truck, or yellow iron equipment, you’re maximizing your time, battery output, and long-term savings. Win, win, and win.

ionic lithium 12v group 31 | 3000 ca | lifepo4 heavy duty diesel starter battery Experience the Apex of Group 31 Battery Technology 

Benefit from the latest in lithium technology with our LiFePO4 Heavy Duty Diesel Starter Batteries. They come with an Emergency Start feature, so you don’t have to worry about being stuck with a dead battery. Simply press a button (or use the App via your smartphone). No annoying service call!

Plus, with the Ionic App, you can monitor your battery’s status using Bluetooth, eliminating guesswork. Enjoy the convenience and peace of mind this brings you, making your trips less stressful, safer, and more reliable.

LiFePO4 Engine Starting Power For Your Heavy Duty Needs

Here at LithiumHub, we take pride in our high-performance, durable batteries, all backed by industry-leading warranties. While lead acid batteries might seem cost-effective initially, their shorter cycle life and frequent maintenance typically lead to higher costs over time (compared to LiFePO4).

While these batteries may offer initial cost savings, their shorter lifespan, and frequent maintenance needs often make them less cost-effective over time compared to our lithium options. Avoid the inconvenience and cost-inefficiency of constant replacements and choose Ionic lithium reliability. AND take advantage of the many technological advances (built-in BMS, Bluetooth technology) that an Ionic starter battery offers you, as the best battery in its class.

Our LiFePO4 Heavy Duty Diesel Starter Battery model is perfect for semi trucks, heavy duty trucks, dump trucks, and yellow iron equipment, bringing longevity, superior performance and dependability to the table. With Ionic, you can enjoy many years of reliable service and starting power. Order your top-performance lithium starter battery today!

Understanding Different Battery Types

When it comes to diesel trucks, selecting the right battery type is crucial for ensuring optimal performance and longevity. There are several types of batteries available, each with its own unique characteristics and benefits.

Here are some of the most common battery types for diesel trucks:

  • AGM (Absorbed Glass Mat) Batteries: AGM batteries are a popular choice for diesel trucks due to their high cranking power. These batteries are maintenance-free and resistant to vibration and shock, making them ideal for the rugged demands of diesel engines.
  • Lithium Batteries: Lithium batteries represent a newer technology that offers several advantages over traditional lead acid and AGM batteries. They are significantly lighter, more efficient, require no maintenance, and have a longer lifespan. Additionally, lithium batteries are more resistant to extreme temperatures and can typically replace multiple lead acid batteries, making them a powerful and reliable choice for diesel trucks.
  • Flooded Lead Acid Batteries: Flooded lead acid batteries are a traditional type of battery still widely used in diesel trucks. They are relatively inexpensive and offer good cranking power. However, they require regular maintenance and can be heavy, which may not be ideal for all applications. Also, flooded lead acid batteries are more prone to spills and leaks and have a shorter lifespan vs AGM and lithium batteries.

Benefits of Lithium Batteries Over AGM

Lithium batteries have several benefits over lead acid and AGM batteries, making them the ideal choice for yellow iron equipment and diesel truck owners.

Here are some of the key advantages:

  • 70% Lighter Weight: One of the most significant benefits of lithium batteries is their lighter weight compared to lead acid and AGM batteries. This weight reduction can improve fuel efficiency and reduce strain on the truck’s electrical system, making it a no-brainer for optimizing performance.
  • Longer Lifespan: Lithium batteries have a much longer lifespan than both lead acid and AGM batteries, typically lasting 2-4x times longer. This extended lifespan translates to fewer replacements and lower long-term costs, making lithium batteries a cost-effective choice for diesel trucks.
  • Half the Weight: Lithium batteries are half the weight of traditional lead-acid batteries – these 3,000 CA lithium batteries are only 30.8lbs (14kg).
  • Increased Power: Lithium batteries provide more power than traditional batteries, making them ideal for diesel trucks and yellow iron equipment with high electrical demands. With 3,000 Cranking Amps (3 sec) and 1,800 Cold Cranking Amps (CCA), these heavy duty lithium batteries deliver the performance you need.

Exceptional batteries

My issue with my stock batteries was I was always killing them within a year.I do a lot of cooking on the truck.I have a slow cooker, microwave, toaster oven.And several other electronics that I run on my truck.I've tried AGM and lead acid batteries never got more than a year out of them.So I decided to try these out. So far, these batteries are fantastic.I bought four of them for the capacity to run.Everything I do not need all 4 start the truck. It used to be my APU would come on within fifteen to twenty minutes after shutting the truck off, now it only comes on when I turn it on for the AC. Im able to run the fans all night, two refrigerators and make coffee in the morning without ever having to turn the APU on and still have plenty of juice to start the engine. I have yet to see how these batteries and the heater perform in the cold but so far im impressed. The less the APU runs the less I spend in maintenance costs. I fully recommend these batteries, they are worth every penny.

Exceptional batteries

I didnt need 4 of these batteries to start the truck but i wanted the extra 200Ah for my 2K watt inverter i have and the appliances i run. These batteries so far have been worth every penny. Before getting these batteries my apu would come on within 15 -20 min of shutting the truck off to charge the old batteries even when they were new. Im able to run the fan on the apu plus 2 refrigerators all night get up make my coffee and still have plenty of power to start the truck and my APU never kicked on. Looking forward to seeing how the heater holds up in the winter and how these perform.

Owner Operators best investment

These batteries exceed anything I have ever seen. 2 of their Ionic Lithium 12V Group 31 | 3000 CA | LiFePO4 Heavy Duty Diesel Starter Battery. Will replace 4 NAPA 1100 cc batteries. The ability to turn them on and off when not in use is the greatest idea yet.

One replaces four.

So far I like it. It is taller than the wet cell batteries I replaced. I have a battery cable that has some for fuse thingy and sits tall. I measured the clearance, while close it’s good. My boss has several trucks with them and they were fine last winter and that’s why I bought mine.

2nd Time a Charm?

After waiting a week the new diesel start battery arrived with a dead cell and defective BMS. Waited another week to receive replacement which appears to have good cells and BMS but just installed yesterday with no start/runtime yet so time will tell. Plan to do YTube review on it eventually.

These batteries are must have items!

I've eliminated my battery issues since our truck has a lot of hotel loads while sitting and the previous lead acid batteries just didn't work long term.. Best solution that we've found and they are lightweight as well.
