The lifespan of a lead-acid battery can vary depending on several factors such as usage, maintenance, and quality. With proper maintenance, a lead-acid battery can last between 5 to 15 years. It’s important to note that the lifespan of a lead-acid battery is entirely variable. How do I know when my lead-acid battery needs to be replaced?
