Core Features
1. Powerful Engine Cranking for Heavy-Duty Applications
The 12V Heavy-Duty Truck Starting Battery is built to ensure reliable engine startup:
- 600A Cranking Current (CCA): Delivers robust power to start large diesel/gasoline engines in heavy-duty trucks, construction vehicles, and industrial machinery—even in extreme cold (-20℃) or heat (60℃).
- Consistent Voltage Stability: Maintains steady voltage during cranking to prevent “no-start” issues, minimizing downtime for fleets.
2. LiFePO4 Longevity for Fleet Efficiency
Leveraging lithium iron phosphate (LiFePO4) technology:
- ≥6000-Cycle Lifespan: Lasts through years of daily use in long-haul trucking, construction, or logistics—drastically reducing battery replacement costs and fleet downtime.
- Stable Capacity Retention: Retains ≥80% capacity after thousands of cycles, ensuring reliable cranking power throughout the battery’s lifespan.
3. IP65 Protection for Rugged Environments
With an IP65 waterproof/dustproof rating:
- Withstands rain, mud, dust, and debris in construction sites, off-road hauling, or industrial zones—protecting the battery from environmental damage and ensuring durability in tough conditions.
4. Extreme Temperature Resilience
Engineered to perform in all weather:
- -20℃ Low-Temperature Cranking: Starts engines in freezing winter conditions (e.g., northern routes, mountainous terrains) without power loss.
- 60℃ High-Temperature Operation: Maintains cranking performance in scorching summer heat (e.g., desert deliveries) while resisting thermal degradation.
5. Efficient Charging & Power Delivery
Optimized for heavy-duty demands:
- 100A Fast Charging: Recharges quickly during driving or downtime, ensuring the battery is always ready for next-use cranking.
- 200A Continuous Discharge: Supports auxiliary electronics (e.g., work lights, radios) in construction vehicles or trucks while retaining enough power for reliable engine startup.
Application Scenarios
The 12V Heavy-Duty Truck Starting Battery is ideal for:
- Long-Haul Freight Trucks: Ensuring reliable engine cranking after rest stops and powering auxiliary electronics during transit.
- Construction Vehicles: Supporting engine startup in dusty, rugged job sites and powering onboard tools/lights.
- Industrial Machinery: Providing cranking power for generators, forklifts, or heavy equipment in industrial settings.
