Electric vehicles (EVs), particularly their battery longevity, is under discussion, highlighting the challenges of proprietary technology and lack of standardization in battery packs. User experiences illustrate that following best practices for battery maintenance can significantly reduce degradation over time. One user notes that while the typical degradation for the battery of a 2019 Model 3 was under 10%, their careful usage has maintained battery health. Additionally, a long-lasting Prius example underscores the durability of hybrid vehicles. The community anticipates future improvements in serviceability and standardization, which could enhance battery replacement and repair options.
