Product Uses
Here are specific application scenarios of car alternator:
1. Daily Urban Commuting
Ideal for daily commutes with frequent starts/stops. The alternator’s stable 13.5-14.8V output ensures on-board electronics (lights, infotainment) work smoothly. Its 88% high efficiency reduces engine load, cutting fuel consumption by 2.5% during rush-hour drives, fitting urban low-speed and high-frequency use.
2. Long-Distance Highway Driving
Perfect for long highway trips (over 500km). With MTBF of 10,000 hours, it maintains consistent power for AC, GPS, and phone charging. The -40℃~120℃ operating range adapts to temperature changes across regions, avoiding power failures caused by extreme heat/cold on highways.
3. Off-Road & Rough Terrain Driving
Suitable for off-road journeys with vibration. It passes 20g (10-2000Hz) vibration tests (ISO 16750-3). The aviation-grade aluminum housing resists dust and impact, while the 500-hour salt spray resistance handles muddy, humid off-road environments, ensuring stable power supply.
4. Commercial Fleet Operations
Essential for commercial fleets (high annual mileage). The 24-month/50,000km warranty reduces maintenance costs. Its plug-and-play design cuts installation time to 30 minutes, minimizing fleet downtime. The intelligent regulator lowers overall fleet fuel costs by 5-8% annually.
5. Extreme Climate Adaptation
Fits regions with extreme climates. In cold areas, it starts smoothly at -40℃; in hot areas, the heat dissipation (thermal resistance ≤0.5℃/W) prevents overheating. Complies with global standards, suitable for markets with harsh weather like deserts or frigid zones.
Product Operate Guide
Installation: Align the alternator with original mounting points (no modification needed), fasten M10×1.5 bolts, and connect wiring as per the vehicle manual. Installation takes ~30 mins; ensure connections are tight to avoid voltage instability.
Daily Check: Monthly inspect wiring for looseness/corrosion. Use a multimeter to test output voltage (13.5-14.8V when idling) – deviations indicate issues. Keep the alternator surface clean to maintain heat dissipation (thermal resistance ≤0.5℃/W).
Note: Avoid long-term high-power use (e.g., all electronics on) with the engine off. When replacing, choose models matching rated 12V/120A specs to ensure compatibility. For faults, refer to the 24-month warranty for after-sales support.
