BYD retroactively extends the warranty on its Blade battery

The Chinese manufacturer BYD raises the warranty for its LFP battery to 8 years or 250,000 kilometers, with a minimum health status of 70%.

BYD continues its strategy of anchoring in the European market by announcing a major evolution of the warranty associated with its Blade battery. This in-house technology, which has become one of the brand’s cornerstones, now enjoys coverage extended to eight years or 250,000 kilometers, while guaranteeing a minimum health status of 70%. This decision is particularly noteworthy as it applies retroactively to all already circulating rechargeable models.

Fully developed by BYD, the Blade Battery has established itself as a distinctive marker in the electric vehicle industry. Its blade-shaped structure, where each cell plays a supporting role, enhances the rigidity of the whole and improves safety in the event of a crash.

Thanks to an optimized architecture, this LFP battery reduces the space occupied by half compared to traditional batteries, thus offering designers more freedom to enhance interior space.

In terms of performance, BYD claims more than 3000 charge and discharge cycles, equivalent to approximately 1.2 million kilometers traveled. The battery has also excelled in extreme tests – overcharging, puncturing, immersion, or temperatures exceeding 300 °C – where it has consistently surpassed international standards. The use of lithium iron phosphate chemistry, without nickel or cobalt, further reinforces the brand’s commitment to reducing its environmental impact.

Beyond this enhanced warranty, BYD maintains an ambitious coverage policy: twelve years with no mileage limit against corrosion, eight years or 150,000 kilometers for the powertrain, and six years or 150,000 kilometers for the general vehicle warranty.

This approach, both technological and strategic, accompanies the rapid rise of BYD in global markets. Already present in 112 countries, the manufacturer claims more than 14 million rechargeable vehicles sold and continues to invest heavily in research, software, and semiconductors. In Europe, its growth is flirting with 300% in 2025 versus 2024, with a goal of selling over 100,000 new electric cars on the Old Continent in 12 months.

Competitors will have no choice but to align with this extension of the battery warranty period. But knowing that the rise of technology is rapid, and that experiential returns grow every day, they should not be overly concerned either…
