How long do the "big" batteries last?

i have heard it before and apparently will continue to hear it frequently in the future...

obtw... it is total BS

 

Apparently it is false.

But do remember there are the "ran out of fuel" threads, and now Toyota will void my battery warranty threads that go around too.

So as long as the battery is treated without abuse, Toyota should not have a reason to void your battery warranty.... and it should last the life of the car.

 

I have 120,000 on my '04. The batteries seem like new. If they go bad, it will likely only be a cell or two, not all of them.

I have 50% of my front brake pads left, and 60% of my rear brake shoes. I changed my plugs at 120,000, even though they looked better than any of my old cars plugs at 30,000.

I have never had to have any repair work done (except for when I hit a dog on the interstate). Replacing a couple of light bulbs, the air and cabin filters, a new set of tires, a couple of minor recalls, one set of spark plugs, one engine coolant change and the oil changes are the complete total of work done. Nothing has broken or gone wrong on this car.

Don't believe the crud you hear. And good job coming here to get the truth. This site has the best information anywhere except for maybe talking to an actual Toyota mechanic.

 

As I tell people who come up and ask at car-shows and the like,
"the life of the car or better". Because of the 40-80% limits
on SOC imposed by the battery computer and the hybrid ECU, wherein
you can do as many "microcycles" as you want without getting into
chemical cycle-life issues on the cells.
.
A couple of Classics are apparently falling victim to a bad cell
or two, but until he got smacked right near his hometown a couple
of weeks ago, Jesse was yay close to 350K on his original battery
and that's NOT a typo. Three hundred fifty thousand. Past the
Vancouver taxi folks by a healthy margin.

All I know is that my battery is warranted for 10 yrs / 150k miles under the CA AT-PZEV warranty. So if it needs replacement at 125k, I get a new one for free.

I doubt that its going to happen that way.

 

heck ... I though the whole battery thing would be a good add to the 'troll' thread in FHOP .... something like, "I've heard the batteries die at such & such mileage, leaving you high & dry" ... there goes that idea

 

But I heard from a friend who's father knows someone who works for a company that sells stuff to Toyota that says the batteries won't last very long.

 

You forgot to mention how they are an environmental disaster too. Looks like you have to go back to Troll School

Yeah, I usually spend my time refuting the trolls or ignoring them completely. I'm not a very good troll.

BTW, on another board, I have had to refute the battery life argument and the environmental disaster argument. Because they heard it from someone or they read that ridiculous CNW marketing fabrication.

People actually believe that crap, usually because they have no critical thinking skills.

 

i read an article a while back by Toyota that said they simulated 21 years of wear on the batteries before they were released into production.

 

For less fortunate warranties (8 years / 100k miles in my country) are a relief the CA policies.

It gives us a "trust margin", even out of warranty.

But at the end, if I still own the PRIUS in 8 years, I'll be thinking to go for a new and more efficient batt, probably "plug-in" and for a lot less money than now. Who knows.

 

Here is an interesting report done by the DOE on the Gen I Prius, as well as the insight and civic. At 160,000 miles they found the Prius battery had degraded quite a bit, but that the effect on mileage was very minimal. As I understand it, the batteries in the Gen II are even better than these. Keep in mind this is just one data point. Battery life will depend on many factors, including temperature, depth and frequency of cycling, etc. Toyota has done a very good job a trying to minimize these effects though.

Another data point, is the RAV4 EV. These had larger NimH batteries, but they were also cycled much more heavily and generally less protected (no gas engine to switch over to). The SoCal Edison test below show these still doing very well at 100,000 all electric miles. Many of these vehicles are still on the road 10 yrs later with their original packs.
