Who still has the 'Original Hybrid Battery' on their Gen. 2

Mine on my 2009 went out about 3 years ago right here on this list. And was replaced with a brand new from Toyota for 1640 I believe it was at the time right here in North Carolina the original battery lasted until I don't know $210,000 I think something like that

 

i don't

 

I believe my hybrid battery in my 2007/2008 Prius is the original battery at almost 140,000 miles.

 

I still have mine. All fine at 163.000

 

Daughter's 07 w/320 kmi and my 07 2/140 kmi both have original batteries

 

I have most of my original battery from 2006 but in 2020 I had 4 modules out of 28 replaced. Still it is working fine after the rebuild.

 

My 2007 just rolled over to 330K with the original traction battery.

 

Yes indeed. Original battery in 2005 Gen2 with approximately 191000 miles.

 

My 2007 Gen 2 has 698k km (433k miles) with the original hybrid battery still going strong.

 

My 2005 still has the original - 420k km (261k miles) and running strong. Amazing machine!

 

So far, 8 out of 8 reporting "yes" are located in cooler climes.

 

My 2009 Gen 2 had the original traction battery at the end of 2023 when it had 215K miles. I don't know after that. I sold the car. It still got good gas mileage and I had never had any warnings that the traction battery wasn't working properly. (No, I didn't dump my car on an unsuspecting buyer. I was open and honest about everything to do with the car when I sold it.)

 

I have mine, but I've only owned the car since May of 2022, I've only put 24k miles on it, got at 136k, now at 160k. Original traction battery, plan to upgrade to lithium project next if it ever goes. Currently having issues and I do not know if it's cvt or what, it's like I'm slipping while driving, engine doesn't sound any different but traction light comes on, thinking about making a post, trying to figure out how to word my problem better. Thinking of buying a parts car now because I'm in love with this car and wanna do the repairs myself and keep it going.

 

I do not think that all of the Gen 2 owners are members of this forum. So you are not going to get a good idea (%) of original OEM traction batteries that are still in use in a Gen 2 Prius.

A more scientific pool would be to ask all the Gen 2 owners on this forum to report their year and mileage and if they have the original OEM traction battery or if they have a replacement battery.

A replacement battery would include:
1. The original OEM battery with one or more modules replaced.
2. An OEM battery that was taken from another car and installed into the Gen 2.
3. A refurbished or rebuilt battery,
4. A new battery (OEM and aftermarket).

 

I don't log into Prius chat very often. I look, but don't log in much.

My 2009 has 140k miles, all in SoCal, and the original hybrid battery. I'm thinking of selling it soon. I "gave it to my daughter 2 years ago" but she never got her drivers license, so my wife was driving it 2-3 times a week to keep it up and she is tired of paying full coverage insurance on it. I'm living in another state or I'd drive it

 

My 2005 HV battery just died 229K mi. And has only been to two drop zones.

 

Ours 2006 batt died at 14-yrs and 195,000 back in 2020 and we got the RAV4HV. It died in the winter which surprised me, I thought we pampered it well enough.

In the years past on PriusChat we did some surveys, which tended to show relatively higher rates of Gen2 HV batt failure than expected, but of course that could be biased. I always suspected Toyota must have made some improvements after about 2007, because lots of 2008 2009 were sold and there would have been a flood of batt fails if they were are like 2006's. We have no data of course except a Consumer Reports survey around 2012 which was too early to see Gen2 batt fail rates.

Gen2 had the generic issue of draining the HV batt totally upon empty gaso tank, which was fixed for Gen3.

Its the rare Gen2 on the road around here anyways anymore, and we tend to hold cars forever here due to hefty annual car tax on new cars.

 

2008 with 267k miles on it and still has original traction HV battery. I bought it used in 2010 with 27k on the odo. It's lived it's whole life in the PNW, so not a lot of high heat exposure.

The gas milage has been getting worse over the last year (35 - 40 mpg) so I've been thinking about replacing the HV battery preventively. All the replacement options seem to have gone up in price in the last month or two. I was intrigued by the project lithium stuff years ago, but got over that with the recent discussions of how poorly engineered they were. Sodium-ion looks intriguing again, but I don't want to be a guinea pig and I'd hate to see my car go up in flames.

Is the general consensus to stick with Toyota OEM (if you can get a parts department to sell them to you) or Cylindrical High-Performance NiMH?
