Compatible with multiple Chery models, this alternator ensures quick ignition, enhanced fuel efficiency, and extended battery lifespan. Ideal as a direct replacement unit, it guarantees durability and consistent performance under diverse driving conditions.
Trusted by global suppliers for its precision engineering and compliance with international safety standards.
Product Advantage
Engineered for exceptional performance, this alternator delivers a robust 120-150A output with precise 14V voltage regulation (±0.5V). It ensures stable power supply for all electronic components—battery, lighting, and climate systems—even under high-load conditions. Advanced electromagnetic design minimizes energy loss, achieving ≥85% efficiency (exceeding ISO 8854 standards). Ideal for vehicles with added electrical accessories.
Constructed with grade-A copper windings and industrial-grade bearings, the alternator withstands extreme temperatures (-40°C to 120°C) and vibrations (30G tested per SAE J1378). Its 60,000-hour service life (3x industry average) reduces replacement frequency. Each unit undergoes 500-hour full-load endurance testing to ensure zero failure in real-world conditions.
Manufactured under ISO 9001:2015-certified processes with 100% performance testing before shipment. Compliant with international standards (ROHS, REACH) to ensure environmental safety and compatibility. Full traceability via batch codes provides transparency, building trust for global distributors and repair shops.
Precisely engineered to OEM specifications for plug-and-play installation without modifications. Includes all necessary hardware (bolts, connectors) and a multi-pin OEM-style plug. Reduces mechanic labor time by 30% compared to generic alternatives, minimizing vehicle downtime and ensuring customer satisfaction.
Features an optimized cooling fan and aluminum alloy housing for superior heat dissipation. Maintains operational temperature 20% lower than conventional models, preventing overheating-induced failures. Ensures consistent performance in stop-and-go traffic or extreme climates.
Designed for worldwide voltage and environmental conditions. Corrosion-resistant coating protects against coastal humidity and road salt. Supports 12V/24V systems (customizable) for broad regional compatibility, making it a preferred choice for exporters serving diverse markets.

Product Uses
Here are specific application scenarios of car alternator:
This alternator serves as a perfect replacement for original equipment when electrical systems show failure symptoms (dim lights, battery warning light, or difficulty starting). With OEM-equivalent specifications and plug-and-play design, it restores stable 14V power output and 120-150A current capacity, ensuring reliable performance for all vehicle electronics systems.
Ideal for vehicles equipped with additional power-consuming accessories (high-intensity lighting, audio systems, or cooling fans). The unit's 150A maximum output provides ample reserve capacity, preventing battery drain while supporting simultaneous operation of multiple electronic devices without compromising performance.
Recommended for preventive replacement at 60,000-80,000 mileage intervals. With ISO 9001 certification and 500-hour endurance testing, it offers reliable performance for fleet operators and repair shops seeking to minimize unexpected breakdowns and reduce vehicle downtime through scheduled maintenance.
Engineered to perform reliably in temperature extremes (-40°C to 120°C). The advanced cooling system and corrosion-resistant construction ensure stable operation in both desert heat and cold winter conditions, making it suitable for global market requirements and varied climatic environments.
Specifically designed to maintain optimal battery health through precise voltage regulation (14V ±0.5V). Prevents both under-charging and over-charging scenarios, extending battery service life by up to 30% compared to conventional alternators, particularly beneficial for stop-start driving conditions.
Product Operate Guide
For optimal performance and safety, professional installation is recommended. Always disconnect the negative battery terminal first to prevent electrical shorts. Verify the replacement unit matches your vehicle's specifications (14V output, 120A/150A capacity). Install using OEM mounting points and reconnect all wiring harnesses securely. After installation, use a multimeter to confirm charging voltage between 13.8V-14.4V with engine running. For detailed instructions, refer to official service manuals. All units are tested per ISO 9001 standards to ensure reliable operation.
