Major Chinese battery and electric vehicle (EV) makers are moving to introduce what could become an industry-wide standard for long-term EV battery warranties, prompting Tesla to develop its own extended coverage plans to remain competitive.
Contemporary Amperex Technology Co. Limited (CATL), the world’s largest battery manufacturer, is working with Chinese automakers including Nio to formalize a 15-year EV battery warranty that guarantees up to 85% capacity retention. The move aims to enhance consumer confidence and strengthen the resale market for used electric vehicles.

Tesla, which currently offers an eight-year battery warranty with a minimum 70% capacity retention, plans to roll out new extended coverage options in 2026. According to an internal email cited in reports, the company will introduce the extended warranty as an optional subscription service priced from $100 per month for additional coverage periods.
“The extended coverage options will be offered starting in 2026,” Tesla said in a message to customers, adding that it aims to provide “flexible choices for long-term battery protection.”
The new initiative follows Tesla’s growing confidence in the durability of its newer battery chemistries, which are designed to last well beyond the standard warranty period. Industry analysts suggest that the subscription-based model could allow Tesla to profit from extended service offerings while maintaining cost efficiency for replacements if degradation occurs.

Meanwhile, CATL has already introduced a 12-year battery warranty for packs used in Nio’s battery swap stations and is expanding its network to meet a 15-year target. The company’s lithium iron phosphate (LFP) batteries used in energy storage systems are rated to last up to 20 years, with minimal degradation in the first five years.
According to Nio, approximately 20 million electric vehicles will fall out of warranty within the next five years, a trend that could weaken the used EV market. The extended warranty framework, Nio said, is intended to “breathe new life into the second-hand EV industry” by reducing one of the major concerns for potential buyers — battery degradation over time.
Tesla’s move reflects an effort to align with evolving global standards while preserving its profit margins through flexible service plans. As Chinese automakers and battery suppliers push for longer coverage, Tesla’s subscription-based approach could mark a new phase in the competition over EV ownership value and battery longevity.
