The lifespan of a battery depends to a very large extent on its duration of use, the temperature and application for which it is intended. Over 80% of batteries fail due to insufficient charging. If, after checking, your battery has more than 80% of its original capacity, it will not be replaced under the warranty because it is considered perfectly functional.
The Dynamp AGM 12V 15AH 200A Auxiliary Battery would be perfect for stabilizing the power supply for electric vehicles, such as the Jaguar Land Rover CX23-10C655-AC.
