Yes, it's 8years or 100,000 miles for the hybrid battery. My Prius battery when out @6 years and ~97,000 miles and they replaced the entire thing under warranty so its like you get a brand new car all over again.
For the Prius it may be because I tried a lot to stay on the battery in town and would feather the throttle to prevent the ICE from turning on. So I may have caused it to wear out quicker. I believe if you drive the car normally the battery will be fine.
