The typical lifespan of a solar battery is 10 to 12 years. That’s about half as long as solar panels usually last, so you’ll have to replace your battery well before your panels come to the end of their useful lifespan. That doesn’t mean your battery will stop working entirely at that point, though. [pdf]
