There are two batteries in the Toyota Prius. Which one are you asking about?

In the US, the entire hybrid system (which includes the hybrid battery pack) is warrantied for 8 years/100,000 miles.

If you are in a California-emission state, the hybrid battery pack in a 2004-2009 Prius is further covered under the CA emissions warranty for 10 years/150,000 miles. (But that is just the hybrid battery and certain emissions components, not the entire hybrid system...) Last I heard the upcoming 2010 Prius will have a longer warranty.

That's a full warranty (not pro-rated). No cost to you for parts or labor.

(But just because the warranty is over, doesn't mean that the item will fail! You don't see bumpers falling off at the end of the 3 year/36,000 mile bumper-to bumper new vehicle warranty that is on most vehicles...)

If for some reason you do need to replace the hybrid battery out of warranty, do note that your Toyota dealer should offer you a $200 rebate/bounty on it, so that it gets properly recycled.

Used Prius hybrid battery packs (such as from wrecked vehicles) have been selling for less than US$1000 on eBay. Why pay a dealer the price of a new pack for a used car? Alternately, an individual bad cell could be replaced, but Toyota dealers usually prefer to replace the whole unit as it is easier than a cell by cell basis.

The price for new Prius hybrid batteries has recently come down. They used to be priced in the US at $2985, but now for the NHW11 model (US 2001-2003 model years) it is $2299 and the NHW20 model (US 2004-current model years) is $2588. (Dealer labor charges (which price varies depending on where you live) for moving an approx. 100 lb. hybrid battery pack could easily add up to another US$1000 depending on your dealer and their competence...)

Average life span? no one really knows. There just hasn't been enough of them failing for us to tell you how long they'll last. (It is still a rare occurrence, even for the US Prius which have been out for almost 9 years now, with many over 200,000 miles without any hybrid battery issues...)
