If you live in an area with extreme temperatures, frequent short-distance trips, or engage in heavy-duty activities, your alternator may wear out sooner. Additionally, lack of proper maintenance, such as ignoring warning signs or not replacing worn-out parts, can shorten its lifespan. Choosing a high-quality alternator and having it installed by a qualified mechanic can also contribute to its longevity.
Keep in mind that these figures are just estimates, and the actual lifespan of a car generator can vary from vehicle to vehicle. For accurate information, it is recommended to refer to the specific maintenance guidelines provided by your vehicle's manufacturer.
