The Fleet Owner's Problem: The High Cost of "Comfort"
Your drivers need power for A/C, heat, and their appliances. But the cost is killing you. You're either burning over a gallon of diesel per hour idling the engine, or you're constantly replacing cheap lead-acid batteries that die in the cold and can't handle deep discharges. Both options cost you thousands per truck, per year in fuel and downtime.
You need a dedicated power solution, not another problem. The TRUCKCOOL B12 is engineered to do one job perfectly: deliver clean, long-lasting power to your sleeper cab, saving you money every single day.
Your Business Benefits: The TRUCKCOOL B12 Advantage 📈
1. Massive Fuel Savings & ROI.
The TRUCKCOOL B12 provides 1280 Wh of power—more than enough to run cab essentials all night without idling. The fuel savings alone can deliver a return on your investment in just a few months.
2. Install It and Forget It (for 10 Years).
With a true cycle life of more than 3,500 cycles, this battery is built to last over a decade. That’s 8-10x longer than the lead-acid batteries you're tired of replacing. Plus, at only 23.8 lbs, installation is a breeze.
3. The Most Cost-Effective Power Upgrade.
If your truck's starting system is already reliable, you don't need to pay extra for a dual-purpose battery. The TRUCKCOOL B12 gives you all the eAPU power you need at a significantly lower price point, making it the smartest financial decision for your fleet.

Related FAQs
🔋 What is LiFePO₄ and why is it better than other lithium or lead-acid batteries?
LiFePO₄ (Lithium Iron Phosphate) is the safest, most stable, and longest-lasting lithium-ion chemistry available.
Compared to other batteries, LiFePO₄ offers:
Unmatched Safety: It is thermally stable and far less prone to thermal runaway than other lithium chemistries.
Long Cycle Life: Lasts for thousands of charge cycles, providing an 8-10 year service life.
Stable Voltage: Delivers consistent power until it's nearly empty.
Eco-Friendly: Contains no toxic heavy metals like lead or cobalt.
🛡️ How does the Battery Management System (BMS) protect my investment?
The BMS is the brain of the system, ensuring safety, longevity, and peak performance.
Our advanced BMS constantly monitors every aspect of the battery and will automatically intervene to prevent damage from:
Overcharging: Stops charging when the battery is full.
Over-discharging: Shuts off power before the battery is completely drained to prevent cell damage.
Extreme Temperatures: Manages operation in both hot and cold conditions.
Short Circuits: Provides instant protection against electrical faults.
🔌 How does the APU battery system recharge?
Automatically, while you drive. No extra steps, no hassle.
Our system is designed for maximum efficiency. The 12V LiFePO₄ battery pack automatically recharges via the truck's alternator whenever the main engine is running. This ensures the APU is fully charged and ready for the next rest stop without requiring any driver intervention or searching for an outlet.
