Core Features
1. Marine-Grade Engine Startup Performance
The 24V 340Ah Marine Starting Battery is purpose-built to ignite marine engines in boats, yachts, and fleets:
- 1800A Cranking Current (CCA): Delivers massive power to start engines reliably—even after prolonged idle periods or in -20℃ freezing conditions.
- Stable Voltage During Startup: Maintains consistent voltage to prevent “no-start” failures, ensuring vessel operations stay on schedule and avoid downtime.
2. LiFePO4 Longevity for Marine Efficiency
Leveraging lithium iron phosphate technology:
- ≥6000-Cycle Lifespan: Endures years of marine use, slashing battery replacement costs for boat owners and commercial fleets.
- High Capacity Retention: Retains ≥80% capacity after thousands of cycles, so cranking power stays reliable throughout the battery’s service life—ideal for vessels with extended operational seasons.
3. IP65 Protection for Saltwater & Wet Environments
With an IP65 waterproof, dustproof, and saltwater-resistant rating:
- Shields the 24V marine starting battery from saltwater spray, rain, and moisture in marine environments—preventing corrosion and damage that plague standard batteries.
- Withstands dust/debris in marina storage or coastal construction, ensuring durability in docks, piers, or offshore platforms.
4. Extreme Temperature Resilience for Diverse Seas
Engineered for marine climates:
- -20℃ Low-Temperature Startup: Starts engines in freezing coastal regions without power loss.
- 51℃ High-Temperature Operation: Maintains peak performance in tropical seas while resisting thermal degradation.
5. Efficient Charging for Marine Operations
Optimized for vessel power needs:
- 100A Fast Charging: Recharges quickly during dockside stops or downtime, ensuring the 24V marine starting battery is ready for next-use engine cranking (vital for multi-trip daily operations).
- 200A Continuous Discharge: Powers onboard systems while retaining energy for reliable engine startup—supporting seamless marine workflows.
Application Scenarios
The 24V 340Ah Marine Starting Battery is ideal for:
- Recreational Boats & Yachts: Sailboats, motorboats, and yachts needing reliable engine cranking for weekend trips or long-distance cruises.
- Commercial Marine Fleets: Fishing vessels, cargo ships, and workboats requiring durable, all-weather starting performance for daily operations.
- Marine Infrastructure: Docks, piers, and offshore platforms relying on backup power or engine startups for maintenance machinery.
