This article explains how used Tesla Model 3 batteries perform over time, highlighting why LFP packs retain significantly more capacity than NCA versions and offering guidance on identifying LFP-equipped cars.

LFP batteries are reshaping the U.S. EV market by cutting production costs and improving durability. Although fewer EVs currently use LFP, major investments from Ford, GM, and Rivian will bring more affordable models to American buyers soon.

New data from Recurrent shows modern EV batteries are highly reliable, with replacement rates dropping sharply across generations. Advanced thermal management, stronger warranties, and falling costs mean battery failures are now rare.

China’s Dongfeng aims to debut a solid-state EV in 2026, targeting 620 miles of range, improved safety, and ultra-fast charging. The announcement underscores China’s lead in next-generation EV battery development.

A new analysis of real-world data shows most EVs retain over 90% of their original driving range after three years. Brands vary, but improvements in battery tech, heat management and software keep degradation modest.

A UK startup has developed a precise thermal-management device that keeps EV batteries cooler and more balanced, potentially cutting fast-charging times by up to 68% while improving range and long-term durability.

A large ADAC study of 28,000 plug-in hybrids finds major battery health gaps across brands. Mercedes PHEVs retain nearly 90% capacity at 200,000 km, while Mitsubishi models lose over 30%, highlighting the importance of battery checks.

Toyota claims its new solid-state batteries could last up to 40 years with 90% capacity retention. Promising greater durability, safety, and efficiency, the breakthrough could transform how long EVs last and how reliably they perform on the road.
