How long do Prius batteries last?

That depends on how you drive them and how you charge the batteries. When charging, batteries produce heat. The faster the charge, the more heat produced. And head will destroy batteries. If you frequently use fast-charge stations, the battery pack might last less than ten years. If you always slow charge, like at home, the pack might last over twenty years. with Prius, a Hybrid, if it's not a plug-in, or the plug-in was rarely used, battery packs have been known to last fifteen to twenty years, but those cars were driven in moderate climates, no excessive heat or cold. there are several sites where you can find detailed information about this, just google this.
