expected lifespan of battery?

welcome!
there's no detailed data, and some of us pip owners have lost as much as 15% over 5 years, while others claim no degradation. it definitely is larger in the first year, and then the degradation seems to go down each following year.

total lifespan is likely 10 years/150,000 miles, that is the carb warranty. some will likely fail before that, but most after. no way of knowing. 175k, 200k, and up. luck of the draw, but also the climate they are in, how they are driven and the care they receive.
also, the percentage of ev/hv driving.

 

I think I would expect 200,000 miles.

 

It is mentioned in the owners manual (free download from the TIS site). I'm "paraphrasing" here, but they indicate it is a part that "wears", and is expected to loose some capacity over time eventually wearing out.

 

Most previous versions of prius taxis are good for 300K miles before the battery dies.

 

taxi's are not relevant to normal use though. very few 300,000 mile stories here. toyota will only repair/replace the battery if it throws a code. that basically means you could be driving around with an anchor, and they wouldn't care.
that being said, it's like that for most plug in's, although, hyundai is offering lifetime warranty to the original owner. but not on degradation, i don't think.

 

This question also came up with the regular Prius and Toyota gave the same answer of "for the expected car lifetime." Since that has turned out to be easily 200k miles in actual use for the vast majority of owners reporting their experiences, it gives me confidence that the Prime battery will have an equally long life.

I *think* Toyota uses 160k miles as it's internal lifetime value but I am not positive.

The 150k CARB warranty is not applicable in this case because we are talking about progressive range loss rather than failure.In a way, that should reassuring since it means that sometime in the distant future the Prime will "only" be a hybrid.

 

Just drive and be happy.....depends on what state you are in....you will have long time to save for HV battery once warranty is out...if you still looking to keep it....

My 2001 Prius went 12 years before the battery failed.

 

There's still Gen 1 Prius putting around on their original NIMH batteries. Your question cannot be answered yet. Not enough data. I can tell you on a lithium ion 2012 PiP, I'm at 120k miles with 20% of that in EV. That equates to a little over 2000 charge cycles over 4 years. Not full charge cycles as Toyota does lot allow that. Battery degradation is around 15%. I'm going to say something else expensive on this PiP will go out before the battery does. The battery is one thing I do not worry about.

 

If you are first time to explore Hybrid car's.....
I would suggest to try used
BMW I3 Rex....12000 miles or less and 1+ year old you can have for less than half what new one was

Even if the battery lasts, the rest of the car does not. Unfortunately the reliability of the i3 has been poor and dealership repair costs are, well, what BMW owners pay.

 

If you have 2015 or newer i will say that all problems where solved and from 2014 and up....
I personally have I3 Rex.....2014 from my Father and beside all little recalls and some issues with tires so far i have never experience any big problems
With 98000 KM so far......

A History of the Prius (and why we can't answer your question)

Gen 1 (2001 to 03) used NIMH cells and they corrode under certain circumstances. As many as 33% have failed after 15 years.

Gen 2 (2004 to 09) also used NiMH cells fixed to corrode less. About 5% have failed in 10 years

Gen 3 (2010 to 15) used an improved NiMH cell and have been almost perfect in the US. (There are odd rumors that they do not do as well in tropical weather. I think they are FUD, but I do not live in the tropics)

Prius PHV (2012 to 2015) the first LiIon Toyota. None are older than 5 years, so far they are apparently perfect.

Gen 4 (2016 and newer) Some models use NIMH and some use LiIon cells, again they are so new no failures should be expected.

Prime (2017 and newer) LiIon cells, less than one year old, so no history of failure.

If you were asking how long your Prius Two's battery would last I would have over a decade and a half of history to predict future longevity and I would predict 25 years. Since you ask about the LiIon battery Prime, we only have 5 years of history, and virtually no failures. Any prediction we make is 100% speculation.

You live in CA, so It is warrantied for 10 years and 150,000 miles. Toyota obviously expects them to really last that long or they go broke replacing them. That is the best I can do.

 

Were you the original owner?

 

Yes. Best little car I ever owned.

 

and really, the whole industry has been very dependable.
