12V 300AH Truck Parking Starting Battery: LiFePO4 Power for Heavy-Duty Vehicles
Product Introduction
The 12V 300AH Truck Parking Starting Battery is a high-performance lithium iron phosphate (LiFePO4) solution engineered exclusively for heavy-duty trucks—seamlessly supporting parking power needs (e.g., cab AC, onboard electronics) and reliable engine starting. With a nominal capacity of 300AH and 3600Wh of stored energy, this battery leverages advanced LiFePO4 chemistry to ensure ≥6000 charge-discharge cycles (retaining ≥80% capacity) while operating in extreme temperatures (-20℃ to 60℃). Built with IP65 waterproof/dustproof protection and 600A cranking current (CCA), the 12V 300AH Truck Parking Starting Battery merges long-lasting durability, robust power delivery, and all-weather resilience—perfect for truckers and fleet operations across diverse environments.

Core Features
1. Dual Functionality: Parking Power + Engine Starting
The 12V 300AH Truck Parking Starting Battery is designed to excel at two critical tasks:
- Parking Auxiliary Power: Powers cab air conditioning, interior lights, infotainment systems, and other electronics without idling the engine—saving fuel, reducing emissions, and enhancing driver comfort during rest stops.
- Reliable Engine Cranking: Delivers a robust 600A cranking current (CCA) to start heavy-duty truck engines consistently, even in extreme cold (-20℃) or heat (60℃)—eliminating “no-start” frustrations.
2. LiFePO4 Longevity for Fleet Durability
Leveraging lithium iron phosphate (LiFePO4) technology:
- ≥6000-Cycle Lifespan: Lasts through years of daily use for long-haul truck fleets, construction vehicles, or logistics operations—drastically reducing battery replacement frequency and total cost of ownership.
- Stable Performance Over Time: Maintains ≥80% capacity after thousands of cycles, ensuring consistent parking power and starting reliability throughout the battery’s lifespan.
3. IP65 Protection for Harsh Environments
With an IP65 waterproof and dustproof rating:
- Withstands rain, road spray, dust, and debris in construction sites, off-road hauling routes, or coastal transport operations—protecting the battery from environmental damage and ensuring longevity in tough conditions.
4. Extreme Temperature Resilience
Engineered to perform in all-weather trucking scenarios:
- -20℃ Low-Temperature Starting: Cranks engines in freezing winter conditions (e.g., northern regions, mountainous terrains) without loss of power or performance.
- 60℃ High-Temperature Operation: Powers parking electronics in scorching summer heat (e.g., desert deliveries) while resisting thermal degradation.
5. High Power & Efficient Charging
Optimized for heavy-duty truck power demands:
- 200A Continuous Discharge: Supports simultaneous operation of parking AC, lights, and accessories without voltage sag—ensuring stable power for onboard systems.
- 100A Fast Charging: Recharges quickly during driving or downtime, so the battery is always ready for next-use parking and starting needs.
Application Scenarios
The 12V 300AH Truck Parking Starting Battery is ideal for:
- Long-Haul Freight Trucks: Providing parking power for cab comfort (AC, fans) during cross-country trips and reliable engine starting after rest stops.
- Construction & Mining Trucks: Supporting auxiliary electronics (work lights, radios) in dusty, rugged job sites while ensuring consistent engine startup.
- Refrigerated Trucks: Powering refrigeration units during parking (to keep cargo cool) while retaining enough capacity for reliable engine startup.
