Product Description
Never Get Stranded By a Dead Starter Battery Again
Cold mornings are hard enough without a diesel engine that won't turn over. If you've dealt with a sluggish crank, a battery that fades mid-route, or a lead-acid battery that needs replacing every year or two, the Ionic Lithium Group 31 Diesel Starter Battery with Heater was built to solve exactly that.
This lithium starter battery delivers 3,000 Cranking Amps and 1,800 Cold Cranking Amps, more than enough muscle to fire up semi trucks, heavy-duty diesel trucks, dump trucks, and yellow iron equipment on the first try, even in freezing conditions.
Built For Diesel Trucks, Backed By Real Cold-Weather Engineering
Standard lithium batteries can struggle to charge in the cold. This one doesn't, thanks to a built-in self-regulating heater that keeps the cells warm enough to accept a charge and deliver full power down to -4°F. No more babying your battery through winter or keeping a backup lead-acid battery around just for cold starts.
Lighter, Longer-Lasting, and Easier On Your Rig
At just 30.8 lbs, this battery weighs a fraction of a traditional Group 31 lead-acid battery, which can tip the scales at 60 to 70+ lbs. Less weight means less strain on your electrical system and an easier install for you or your mechanic.
It's also built to outlast lead-acid and AGM batteries by 2 to 4 times, so you're not budgeting for a replacement every season. Add in maintenance-free operation, no acid, no corrosion, no watering, and the total cost of ownership drops fast.
Ready When You Need It
Every battery ships with Bluetooth monitoring and an Emergency Start reserve, so you can check your charge status from your phone and recover from an accidental drain without calling for a jump. It's the kind of peace of mind that matters when you're hours from the nearest service stop.
Upgrade your diesel truck or heavy equipment with a starter battery built to handle real winters and real workloads. Order your Ionic Lithium Group 31 Diesel Starter Battery today and get free shipping from Battery Mart.
Frequently Asked Questions
Will this battery fit in my existing Group 31 battery tray?
A: Yes. This battery matches standard BCI Group 31 dimensions (12.9" L x 6.8" W x 10" H) and uses the same post layout as a lead-acid battery, so it drops into your existing tray and cables without modification.
Can this battery actually start a diesel engine in freezing temperatures?
A: Yes. Unlike standard lithium batteries, this one has a built-in self-regulating heater that keeps the cells warm enough to charge and deliver full cranking power in temperatures as low as -4°F.
Do I need a special charger or alternator to use this battery?
A: Your existing diesel truck alternator will charge this battery normally. For off-vehicle charging, use a lithium-compatible (LiFePO4) charger rather than a standard lead-acid charger to ensure proper voltage and charge profile.
Can I wire multiple batteries together for a 24V or 48V system?
A: Yes. Up to four of these batteries can be connected in series for higher-voltage systems, and an unlimited number can be connected in parallel to increase total capacity.
How is this different from the lead-acid battery I'm replacing?
A: It delivers the same or greater cranking power at less than half the weight, lasts 2 to 4 times longer, and requires zero maintenance. It also adds features lead-acid can't, like Bluetooth monitoring and an Emergency Start reserve.
