The battery is the most crucial component of an electric vehicle; thus, it comes with a warranty to assure the buyer. However, the quality and terms of warranty differ from manufacturer to manufacturer. The car model and model year also play an essential role. Eight years is the most common warranty term for EV batteries offered by the leading automakers in the USA. In comparison, some may extend it to up to ten years. Several clauses are mentioned in the warranty under which your warranty is nullified or not applicable. So, make sure you check all the parameters before the purchase.
