A Chinese car battery-maker says it is ready to manufacture a product capable of powering a vehicle for 1.2 million miles (two million kilometres) across the course of a 16-year lifespan.

Axar.az reports citing foreign media.

By contrast, most automakers only offer warranties ranging from 60,000 to 150,000 miles over a three to eight-year period on their cars' batteries.

Contemporary Amperex Technology has not revealed who it intends to supply.

But it was previously reported that the battery was co-developed with Tesla.

The latest news was revealed in an interview Catl's chairman gave to the Bloomberg news agency.

"If someone places an order, we are ready to produce," it quoted Zeng Yuqun as saying.

He added that it was set, however, to cost a 10% premium over the batteries it already supplies.

The company signed a two-year deal to supply batteries for Tesla's Model 3 cars in February. Its other clients include BMW, Daimler, Honda, Toyota, Volkswagen and Volvo.
