This premium alternator is engineered for Chery vehicles, delivering exceptional reliability and power output. With a maximum output of 120-150A, it ensures stable voltage supply (14V) to support electrical systems like batteries, headlights, and air conditioning, even under high-load conditions.
Constructed with durable brushes and bearings, it undergoes rigorous quality testing to exceed ISO 9001 standards. Compatible with multiple Chery models, it offers a service life of over 60,000 hours. Trusted by global suppliers, this alternator guarantees quick ignition, efficient energy conversion, and extended battery life. Ideal for replacement or upgrades, it meets international performance and safety requirements.
Product Advantage
Our alternator is engineered for exceptional performance, delivering a robust 120-150 Amp output with a rock-solid 14V voltage regulation. This ensures all vehicle electronics—from advanced infotainment systems to powerful headlights and climate control—receive a consistent and reliable power supply, even at idle or under high electrical load. This high efficiency significantly reduces the risk of battery drain and electrical system failures, providing end-users with unparalleled reliability and peace of mind.
Built to last, this unit incorporates precision-grade copper windings and high-grade carbon brushes that minimize electrical resistance and wear. Coupled with premium sealed bearings lubricated for life, it effectively withstands extreme temperatures and harsh operating conditions. Rigorous endurance testing confirms a service life exceeding 60,000 hours, drastically reducing replacement frequency and offering superior long-term value for your customers and minimizing warranty claims.
Every alternator undergoes a stringent 100% full-load performance test and a simulated 72-hour continuous operation test before shipment. Our manufacturing process is ISO 9001:2015 certified, guaranteeing that every unit meets strict international standards for quality, safety, and performance. This commitment to excellence ensures you are delivering a product trusted by professional distributors worldwide, backed by full traceability and reliable documentation.
Designed with precision using OEM specifications, this alternator guarantees perfect fitment for a wide range of Chery vehicles without any modification required. It comes as a complete, ready-to-install unit with all necessary hardware. The plug-and-play design ensures a smooth and error-free installation process for mechanics, boosting their efficiency and customer satisfaction. This seamless compatibility is key to building a reputation as a hassle-free supplier.
The alternator features an optimized internal cooling fan and ventilated housing design that dramatically improves airflow, keeping operational temperatures low even under maximum load. This advanced thermal management prevents overheating, a common cause of alternator failure, and ensures consistent energy conversion efficiency above 85%. This results in less strain on the engine, lower fuel consumption, and prolonged battery life.

Product Uses
Here are specific application scenarios of car alternator:
Product Operate Guide
For optimal performance and safety, please follow these guidelines. Always disconnect the negative battery terminal first to prevent electrical shorts. Ensure the replacement unit matches your vehicle's specifications for voltage (14V) and output (e.g., 120A/150A). Install the alternator securely, reconnect all wiring as per OEM specifications, and check the multi-pin connector is fully seated. Finally, reconnect the battery and start the engine to verify stable charging voltage (13.8V-14.4V) using a multimeter.
