Yuasa Car battery YBX3750 12V 66Ah 660A (YBX3000 Series - US Spec)

The Yuasa YBX3750 is a specialised 12V starter battery from the YBX3000 SMF series, which was explicitly developed for American vehicles (US imports). With a capacity of 66 Ah and a powerful cold cranking current of 660 A (EN), it corresponds to BCI Group 75. The special feature of this battery are the side terminals, which are characteristic for many models from General Motors (Chevrolet, Pontiac, Buick) and other US makes. Thanks to the sealed SMF technology, it is maintenance-free and provides reliable starting power.

• High starting performance: With 660 A cold cranking current, it offers enough power for large-displacement V6 and V8 engines.

• State of charge indicator: Equipped with the "Magic Eye" for quick visual control of battery status.

The specialist for US cars

The YBX3750 is the first choice for owners of US imports. It replaces the original BCI Group 75 battery that was installed in countless Chevrolet models (e.g. Corvette C4/C5, Blazer, Camaro), Pontiac, Oldsmobile or Buick. As these vehicles often have very tight battery compartments and the cable connectors are specifically designed for side screw fixing, a standard European battery with posts on the cover will not fit here.

FAQs about the Yuasa YBX3750

What are "Side Terminals"?

Unlike European batteries, which have lead posts on the cover, the YBX3750 has internal threads on the front side wall. The vehicle's battery cables are screwed in directly there. This system is typical for brands of the General Motors group.

Will this battery fit my Corvette or Camaro?

If your vehicle requires a "Group 75" battery and has the terminals on the side, then yes. This applies to very many generations of US sports cars and SUVs. Please compare the dimensions and the position of the connections.

Is this battery suitable for start-stop?

No. The YBX3750 is a conventional starter battery. It is not designed for start-stop systems.

Do I need adapters for the terminals?

If your vehicle has original US cables for side terminals, you do not need adapters. However, if you wish to use the battery in a vehicle with standard clamps (which is rarely sensible), you would need special screw-in posts ("charging adapters") to use round posts again.
