Batteries across many of the vehicles currently on the market have warranties of up to 4-8Ā years dependent on the brand. Long-term battery replacement is yet to be seen on many EVs on a wide-scale basis as the vehicles are so new to the market. This is something that can only be seen in the early hybrid vehicles, that occurred around the 10-year mark. In saying this, the level of technology and battery has greatly advanced in the last ten years, similar to that of mobile phones and laptop computers.
