Prius battery life and replacement cost?

[morris]

My wife and I are considering the purchase of a new Prius. Does anyone how long the batteries last or what they're replacement costs are? How does the car behave when the batteries are nearing replacement?

Does anyone know when the 2006 Prius' will be available?

thanks, Morris

Morris,
There is a great search feature on this site that can answer your questions much better than I, however I will give it a shot.

There is sno real answer to your question as with the exception of accident damage there is no record of a 2004 or later Prius battery failing. If it should fail there is an 8 year 100,00 mile warranty.

Welcome to PriusChat, Morris. Prius HV battery replacements have been rare in the 2001-2003 model, and perhaps none at all in the newer model yet. I believe the US warranty is 100,000 miles in most states and 150k in Calif. and a few other states.

Just yesterday I heard Dave Hermance (one of Toyota's chief engineers) say that a replacement battery for the classic model costs $2500 and that the new model is less (it's smaller). I had previously heard numbers closer to $4K. He also mentioned Toyota's lab testing of batteries to 150k miles with no measurable degradation.

The Odometer Champ is probably Andrew Grant's Prius taxi fleet in Vancouver BC. No battery replacements there yet.

Sad to say, a steady supply of used HV batteries comes from wrecked vehicles. These typically sell for $400-$1000. This is the alternative to buying new.

Hypothetically, a battery failure by slow degradation would probably present itself as reduced power, performance, or fuel economy. There might be warning lights on the display, that would lead the technician to test the HV battery.

All I'll add is that I certainly don't think potential battery replacement should be a consideration. There are plenty of other components in any vehicle, that are just as unlikely to fail during the lifetime of the car that could be just as expensive to replace.

As far as when 2006 models will be available - I don't think I've seen any hard facts yet. Probably the only way we'll know for sure is when someone posts that they've picked on up.

because of automatic features and a dedicated computer designed to take care of and monitor the battery, expected failure rate for life of vehicle (they used 180,000 miles) was less than 1%

there has not been a traction battery replaced as of yet due to wear and tear. replacement costs will go down just like any new technology does as it becomes popular. current costs are at the $4,000 range give or take a grand plus install (since it wouldnt be much if not out of warantee)

one thing i did, (now dont know how well this translates as there is too much i dont know, casing, packaging, special circuitry for multi-battery setups, etc) but i went to batteries plus and priced 28 7.2 volt NiMH batteries and they were 28.72* 28 = $800 or the extended duty batteries 36.72*28=$1000....

so like i said, not really a comparison, but as you can see, its the technology that is the expensive part, not the materials. that tells me that the cost will go down.

i fully expect the price to be around $1500 in a few years after there is couple million on the road. when there is that much market, there will be competition and we will benefit.

Main (Traction) Battery is not likely to be a problem, particularly with the 10y/100,000m warranty (15y/150,000m in California). However, the main battery for a current model Prius is currently available on eBay... The link:

The Seller appears to be "parting out" a wrecked Prius. Seems the wildly varying estimates, as high as $6,000, are unrealistic.

I think I read in the owner's manuel somewhere that the battery will last like 150,000 miles and then right there along with that statement I'm pretty sure it said too the reason the battery lasts so long is because of the way it is utilized by the computer. Which is that the battery is never allowed to get too discharged nor fully charged, instead the battery is kept in a suspended medium charge. I would like to know if someone else can confirm this.

I tell you what this site ought to just be made into a Prius Owners Manuel cause there really isn't any reason to ask questions here when every question you can fathom has already been answered by someone somewhere. I just did a search for my question above and found the answer. http://priuschat.com/index.php?showtopic=1...battery+charges
So nevermind.

The HV battery is computer controlled to keep it's charge at no lower than 40% and no more than 80% SOC (State of Charge) in the Generation II (2004-2008) Prius. If you run out of gas and try to drive on battery only you will not be able to do it for more than a short distance, at which time your dash will light up like a Christmas tree and shut you down. The Gen I (2001-2003) did not have this safety feature, so if one ran out of gas and did not heed the warning in the manual against driving on battery only, it was possible to drain the HV battery below 40% and kill it. So you are correct. It seems to seek about 5-6 bars, or about 60% SOC. But even when it is at 2 purple bars it is still at 40%. It does an excellent job of taking care of itself and we just get to drive it and have fun!

PS. There is a PC member with 322,700 miles on the original battery in his 2002 Classic Prius - still going strong.

holy thread revival!

Yeah also Toyota didn't really give a reason for the condition at 150,000 miles. Does Toyota mean the battery will fail or degrade a certain amount at 150,000 miles?
