Core Features
1. LiFePO4-Powered Heavy-Duty Cranking
The Lithium Iron Phosphate Starting Battery harnesses LiFePO4 chemistry to deliver:
- 2100A Peak Cranking Power: Ensures reliable startup for large diesel/gasoline engines in trucks, excavators, and fleet vehicles—even after prolonged idle periods or in sub-zero temperatures.
- Stable Voltage During Startup: Prevents “no-start” failures, keeping logistics, construction, and industrial operations on schedule.
2. Long Cycle Life with LiFePO4 Durability
Lithium iron phosphate technology enables exceptional longevity:
- Thousands of Charge-Discharge Cycles: Outlasts lead-acid batteries by 3–5 times, slashing replacement costs for fleets and heavy machinery operators.
- ≥80% Capacity Retention: This Lithium Iron Phosphate starting battery maintains consistent cranking power throughout its extended service life, ensuring years of reliable performance.
3. Extreme Temperature Resilience
Engineered to perform in all climates:
- -35℃ Low-Temp Startup: Starts engines in arctic conditions, mountainous winters, or cold-storage environments without preheating—critical for northern-region fleets and equipment.
- 55℃ High-Temp Operation: Maintains peak performance in desert climates, industrial heat, or summer operations, resisting thermal degradation common in traditional batteries.
4. Rugged Build for Harsh Environments
Designed to endure heavy-duty use cases:
- Vibration & Impact Resistance: Withstands the rigors of off-road trucking, construction sites, and industrial machinery operation, ensuring durability in high-stress scenarios.
Application Scenarios
The Lithium Iron Phosphate Starting Battery is ideal for:
- Trucks & Commercial Fleets: Long-haul trucks, delivery fleets, and utility vehicles requiring daily reliable engine starts in diverse climates.
- Industrial Machinery: Excavators, bulldozers, generators, and manufacturing equipment with high startup demands and exposure to extreme conditions.
- Off-Road & Heavy Equipment: Mining vehicles, agricultural machinery, and outdoor power systems needing robust cranking power in rugged environments.
