Zeus A275L N62 Alternator with Terminal Block
The highest power output alternator in its size/class.
Features:
- Engineered for High Energy Production.
- Suitable for Marine, RV, Military, and Commercial applications.
- Rapidly charges large battery banks.
- Coolest operating temperatures for increased performance. Runs 8 - 20% cooler than incumbent alternators due to:
- Heat shedding coatings
- Rectifier located on housing exterior
- Dual cooling fans
- OEM Components
- It is optimized for performance at idle speeds.
- Reduces the need for a generator by creating additional power with your engine.
- Unleash peak performance with E-Coat/Cerakote. Our advanced coating absorbs less heat, keeping the A275L cooler. This translates to more amperage for sustained periods.
- Use an ARCO Zeus Bluetooth alternator regulator for maximum performance or lithium battery charging.

The ARCO Marine Zeus A275L N62 Alternator is engineered to deliver the highest power output within its size and class, making it an ideal choice for demanding marine, RV, military, and commercial applications. Designed for rapid charging of large battery banks, this alternator provides reliable power where you need it most. Its advanced construction features heat shedding coatings, an exterior rectifier, dual cooling fans, and OEM components, enabling it to operate 8-20% cooler than traditional alternators, which translates into increased performance and durability. The A275L is optimized for performance at idle speeds, reducing reliance on generators by generating additional power directly from your engine, thus enhancing overall efficiency. Coated with E-Coat/Cerakote, it absorbs less heat, maintaining cooler operating temperatures and allowing for sustained high amperage output during prolonged use. For maximum performance, pairing with an ARCO Zeus Bluetooth alternator regulator or lithium battery charging system is recommended. Certified to SAE J1171 standards and proudly made in the USA, this alternator is built for reliability and long-lasting performance. The unit features a 12-volt system with 16 rotor poles, a large stator, and a robust frame, weighing approximately 14.9 pounds. It includes a side-mounted M8 threaded battery post, a standard 6-groove pulley, and is designed to replace several Mercedes and BMW alternators, including models from 1999-2006 and the factory dual alternator units from 2007 and up. Its maximum output reaches 311 amps at cold start (9,000 RPM), with sustained outputs of 227 amps hot at 6,000 RPM and 198 amps at idle speed. The alternator's regulation is external only, supplied with a terminal block and P-type harness, suitable for external regulators such as the ARCO Zeus Bluetooth regulator. Built for durability, it features avalanche diodes rated at 50A, and its maximum continuous operating temperature is 110°C (230°F), ensuring consistent performance in harsh conditions. This versatile alternator is an excellent replacement for Mercedes and BMW models, including Sprinter 1999-2006 and factory dual alternators from 2007 onwards, providing powerful, reliable energy generation for your vehicle or marine setup.
