Product Description

A Smarter, Stronger Cranking Battery for Your Vehicle: Ionic Lithium

ionic lithium 12v s9 | 1400 ca | lifepo4 car post starter heater battery + bluetooth Many have come to expect the bare minimum from their car batteries—just enough power to start the motor and not much more. But why settle for that?

Our Ionic Lithium Cranking Battery goes beyond the basics, delivering reliable, long-lasting performance in even the toughest conditions.

Whether you’re dealing with extreme weather, an unexpected dead battery, or just want a worry-free ride, this battery is built to keep you moving.

Here’s what makes it a game-changer:

Bluetooth Connectivity

Check Battery Status From Your Phone & Stay Informed Anytime, Anywhere

Keeping tabs on your battery just got easier. With Bluetooth connectivity, you can check its charge, health, and performance anytime, anywhere from your smartphone or tablet. The app is easy to use, compatible with most devices, and provides real-time updates—so you always know your battery’s status without any guesswork.

Emergency Start Function 

Be Ready for the Unexpected With Built-in Jump Starting

A dead battery always seems to happen at the worst time, but our lithium starter battery has you covered. It features an emergency start function that reserves 25% of its charge for when you need it most. If your engine won’t start, simply use the Ionic App to reactivate the battery or press the emergency start button—no jumper cables or assistance needed. Just a reliable backup to get you moving again.

Built-in Heater

Smooth, Reliable Starts in Frigid Weather

Cold weather can put a strain on any battery, and traditional options often struggle when temperatures drop. But our lithium starter battery is built to handle the cold better. With an integrated built-in heater, it helps ensure smoother starts in freezing conditions. While no battery is completely immune to extreme cold, this helpful feature significantly improves performance—so you can hit the road with confidence.

Long-Lasting Power

Built to Endure: 2-4 Times Longer

Unlike traditional car batteries that typically need replacing every couple of years, our lithium starter battery is designed to last 2-4 times longer than standard lead-acid options. That means fewer replacements, more time on the road, and greater long-term value. With reliable, consistent starts for years to come, you can be satisfied knowing you have a battery that works great and is built to go the distance.

Lightweight & Compact

Get the Power Without the Bulk

ionic lithium 12v s9 | 1400 ca | lifepo4 car post starter heater battery + bluetooth

One of the standout features of our lithium battery is its lightweight design. Weighing just 14.6 lbs, it’s up to 70% lighter than a comparable lead-acid battery.

Lower weight makes it easier to handle and quicker to install, and can even help improve fuel efficiency by reducing overall vehicle weight.

Plus, its compact design allows for a better fit in tighter spaces, making it compatible with a wide range of vehicles.

Advanced Battery Management System (BMS)

Superior Protection = Battery Longevity

This battery isn’t just powerful—it’s designed for long-term reliability. Equipped with an Advanced Battery Management System (BMS), it actively monitors voltage, current, and temperature to keep performance stable and efficient, protecting both your motor and electrical system. The BMS also prevents overcharging and temperature extremes that could cause damage, ensuring the battery you purchased stays in peak condition for the long haul.

Fast & Easy Drop-in Replacement

Installing a New Battery Has Never Been Easier

This lithium car battery is sized to fit just about any everyday car or truck, so installation is as simple as dropping it in, making for a quick, easy upgrade.

The Smarter Choice for Your Vehicle

Upgrade your driving experience with a lithium battery that’s up to 70% lighter than lead-acid, yet delivers 1,400 cranking amps for powerful, reliable starts. Built with Grade A cells only, it ensures top-tier performance in any season—whether you’re starting up in extreme cold or heading out on a routine drive.

If you’re still relying on your original battery or one like it, it’s time for an upgrade. This lithium option offers Bluetooth monitoring, an emergency start feature, and a built-in heater for cold weather, keeping you capable and ready for whatever the road throws your way. Its compact design makes installation easier and even helps boost fuel efficiency, while its long-lasting power means fewer replacements over time.

Say goodbye to maintenance headaches and unreliable starts. Upgrade to a smarter, more capable battery that keeps you on the road longer. Make the switch today.

Frequently Asked Questions

What vehicles is this battery designed for?

The Ionic 12V S9 with car posts is a cranking battery built for automotive use — gas cars, pickup trucks, duallys, and diesel trucks. It delivers 1,400 cranking amps (1,100 CCA), making it ideal for engines from 250hp up to 450hp, as well as smaller engines. The Group 25 size and standard car post terminals make it a drop-in replacement for most everyday vehicles.

Will it fit my existing battery tray?

Yes. The S9 is a Group 25 (BCI) starter battery with standard car post terminals, so it’s sized to fit just about any everyday car or truck and installs as a true drop-in replacement — no wiring changes, no modifications, no tray adjustments. Just connect and go.

What is the built-in heater, and when does it work?

This battery includes an integrated heater that helps ensure smoother starts in frigid weather. Cold conditions strain any battery, and traditional ones often struggle when temperatures drop — the heater helps the cells stay in a safe operating range so you can crank reliably on cold mornings. While no battery is completely immune to extreme cold, this feature significantly improves cold-weather performance.

What is the Emergency Start feature?

The Emergency Start function reserves 25% of the battery’s charge for critical situations. If your engine won’t start, you can reactivate that reserve by using the Ionic app on your phone or by pressing the emergency start button on the battery — no jumper cables, no second vehicle, no roadside assistance required. It’s a built-in backup that keeps a dead battery from leaving you stranded.

How much lighter is it than a lead-acid car battery?

The S9 weighs just 14.6 lbs — up to 70% lighter than a comparable lead-acid battery — and is rated for 3,000 cycles at 80% depth of discharge, lasting 2 to 4 times longer than a standard lead-acid car battery. Lower weight makes the battery easier to handle and quicker to install and helps with fuel efficiency, while the long lifespan means fewer replacements and more time on the road.
