    About how long does the high voltage battery last? I’m use my car mostly on local roads so the electrons are being used as designed. As opposed to someone who is just driving on the highway. In that case I can see how battery life would be diminished. Just out of curiosity will it last til 200k miles. That would be awesome. If not maybe i need to save some money for a replacement battery. I love my car and do not wanna part with it even if it means replacing the battery. Please respond quickly as my attention span is would is more goldfish than human

    i believe it is designed to last between 150 and 200,000 miles. if nj is a carb state, you have a 10/150 warranty. otherwise, it is 8/100.
    unfortunately, each battery is not 'average', and it is always a good idea to have a small nest egg for out of warranty repairs, be it for the battery, or any other expensive prius system.

    My thought is 10yrs and mileage does not matters as long as driven regularly. If you live somewhere hot you might not make it 10yrs.

    With that said my previous 2005 Prius is at 248k miles and still running original battery. Gets 46mpg avg still too.

    It's a combination of age and mileage.
    Here is likely a bell curve of when failures occur.

    Let's assume car is driven regularly and an average number of miles is driven. (no snowbirds leaving their aging car sitting for months unused in a cold garage. No taxicabs that run 18 hours a day)

    Making it to 200k or beyond without a pack failure may be possible, but not the norm.

    Between 150k and 225 it would be likely that you would need to deal with the battery. About a $2,500 proposition.

    If yours last longer great. But I wouldn't bet the farm in it.

    A hybrid is t necessarily going to save you any money, but you certainly will lower your overall consumption of gas and pollution emitted.

    So your 2013 Prius C hybrid battery failed at 120,000 miles?

    You are definitely on the early/lower mileage end of failures.
    Thanks for the data point.

    If you want an Average, you need to ask again in at least 10 years.

    I read somewhere that the battery was designed to last the lifetime of the car whatever that means. I guess if he battery goes bad and you junk it then that is the lifetime of the car. It is what it is.

    Battery life will be more dependent on years as opposed to mileage. 12-15 years on average, which will be dependent on a variety of factors such as climate, mileage, if the car not driven for extended periods, etc. I've seen high mileage older cars (2004 w/300,000 miles) on the original battery and the same model year car with only 90,000 requiring battery replacement.

    That's what will happen to me. That HV battery dies, I'm towing it to my sons house where it will be disassembled slowly. I'm not spending that kinda cash to keep a car rolling.


    There's an individual who just posted this week in the "C" forums. HV battery dead at 101k...

    $2,000 is too much?

    For me yes, I'm not messing with it. It's a car, not a family member. Got a son and a brother who are both Master techs. (Honda/GM) So when it dies, I'm going with something my son or brother can work on. Well, I should just say Honda because there is no way I'd ever buy a GM product.

    If I had to spend $2000 on a car repair, I'd buy a cheap a** civic for $1000 off my son and drive it for 80k miles.

    I believe the Prius C only comes with a 10 year 100k traction battery warranty even in carb states.
    Are the individual battery modules the same as a non C / non plugin 3rd generation Prius?

    No, it's 8 year / 100,000 in non carb states. Just looked at the warranty booklet...

    I read somewhere that the actual battery life is unknown, because it is much more likely that the car will be totaled. There are many cases that document prius' lasting over 300K miles. As for cost, a "battery pack failure" is virtually non-existent. The "battery" is actually made up of 28 cells which are independently replaceable. I am on my second prius (first one lost when I was hit making a left turn). My used car dealer, at Savy Motors in Alpharetta, GA told me that if there is a battery failure, most of the time it is due to one or more of the cells doing bad. If so, he can put in a refurbished cell for under $50, plus a diagnostic fee to locate the failed cell(s). So, you can possibly have it repaired for under $200!

    I bought a used HV battery that had 29k miles on it and been good ever since.
