Do Toyota Hybrid Batteries Last Longer with Extreme High Mileage Driving?

My 2002 Prius has 370,000 miles plus and keeps on going!

I sold my 2005 Prius with 386k+ plus to a Pizza restaurant few years ago. It still on original everything except engine mount, the potholes in NYC really does damage to my car. Transmission still smooth brake still good mpg dropped to 40 in winter and summer. I bought the car used with high mileage too. It made me love to drive further and longer. The smooth comfortable driving plus great mpg oh don't forget it practical i help my friend transport a 70 inch tv and it fit once I fold the rear seats.

My 2015 PriusC has 47,000 miles on it and I had to buy a new starter battery last week. I haven’t been driving since covid and for the last month it has taken 2, 3, 4, even 5 cranks to start and sometimes then it would not start. The dealer said the car had to be driven at least 30 minutes a day at least twice a week. So, you the theory about big mile numbers, no problems could be very true when small mile numbers kind of killed my car.

I bought my 2018 Prius2 in late march of 2020 with 45k miles on it. As a Medical Courier, as of today 02/20/21, I have 155k on the odometer. That's 110k miles in 11 months. I service it at least once a month and keep up with all the recommended services at specific mileage markers/intervals. Who knows how long it'll last me, but my replacement will surely be a Prius Prime sooner or later.

Had my 2001 Prius for 14 years and 180,000 miles and the battery pack had to be replaced at around 110k miles. Now driving a 2016 Sonata PHEV and Hyundai is in the process of replacing the pack after only 82,000. I love seeing stories of battery packs lasting forever but unfortunately that hasn't been my experience.

I have a 2015 Camry Hybrid which is basically the same system. I am a loan signing agent and drive a lot. The car has 235,000 mikes on it and going strong. Only repair was a water pump on the ICE engine. The hybrid system will definitely outlast the ICE. I have owned it since new and it has had only the basic maintenance done regularly.

I a on my 4th Prius. I drive over 200miles 4 days per week. I average over 30, 000 miles a year on my cars. I got rid of my 2010 prius at 294, 000 mi. Battery was still good. 2 of my cars were totaled in winter driving accidents. Got my 4th used 2014 with 53, 000 mi. on it and will drive it until 300, 000 before trading. I do not look for anythingbut a Prius.

2008 Prius 270k water pump for inverter only repair.

I have a 2007 Prius with 495k miles. We replaced the hybrid battery at around 485k miles. This was only after we stopped driving the car and it started to sit. My 2017 Prius Prime has 170k miles, no issues.

So apparently my 2008 is just breaking in at 240,000 miles

I have a 2012 lexus ct200h with 247000 miles and i just have “check hybrid system” light.

I traded my 2019 Avalon LTD hybrid at 65,000 miles when I heard about broken bones of people with small cars 3,200lbs to 3,600lbs by SUV's and pickup trucks at 4,000lbs plus w/ a new 2021 Sienna platinum W/AWD, the gas milage is not the same but, the ride is much more positive and comfort than want they did to the Avalon ride which is more performance oriented (age is 85 & 90 yrs) The ride is fantastic, handling is smooth snow performance with AWD is great......gas milage is 28mpg to 40mpg over all is about 33mpg which is fine for a 4,800lbs machine that gives you great gas mpg and a smooth ride with the extra air bags this year for Sienna in the second row w/heated seats and plenty of room for the third row! If we are hit with an SUV or Pickup truck, most of which are 4,500lbs to 5,000lbs will equal damage and survive with minimal harm! We are one of those groups that drive at the speed limit with cruise control turned for protection to keep our distance automatically behind the car leading us, the lane trace assist is wonderful though! Keep up the good work Toyota! I've been driving Toyota's for 43 years! R.W.Riley

My 2010 Lexus hs250h has 265000 miles and it still going with just routine maintenance. Putting new struts on the front end this weekend.

A courier as well, I bought a new 2014 Lexus CT 200h (3rd gen Prius powertrain) for my job after running 143k miles on my 2012 Prius C2.

It's currently sitting at 629k miles with the original hybrid battery (12v battery replaced once). Fun what I've read, Toyota designed the hybrid battery to endure charge/discharge cycles over time, so the battery should last 10 to 12 years or so, even when used a lot. My car is 90% highway miles, driven 6 days a week for 6.5 years now.

Hi Jeff,
I recently bought my second Gen 2 with 170000 km on it and sold the old one with 297000. There’s hardly any difference in driving. But from the fact (or feeling) that the new one accelerates a bit quicker. Now I read somewhere (maybe written by you) that the battery looses some punch over the years/mileage. It would make sense, since other batteries (laptop) loose power after time. I was wondering wether this was al just imagination or that there is any sense to it.
Greetings from Amsterdam, Netherlands.

I live in Australia. I bought a 2012 Prius i-tech 4 years ago with 65k on the clock.
It now has 220k and still runs like a dream.
I do 250 km a day, mostly highway.
I service it properly.
I haven't had an issue, still gives me 4.1 to 4.5 litres per 100 kms.
With Toyota, I believe...keep them serviced, they'll keep on going.
Look @ the Hilux.

A common theme here is that the ICE wears out before the traction battery (12v batteries are another thing altogether). I was a big fan of Toyota and had several including a Gen 2 Prius which was faultless. but they’ve lost their way with electrification and in 2019 I went with the Kia e-Niro, a brilliant car without a troublesome ICE of course. I fully expect this car to see me out as other EVs with proper battery management systems like the Kia/Hyundai cars have are seeing 300,000 to 400,000 on the batteries. That should do me.

I have a 2006 Lexus RX400H with over 335,000 miles. Original hybrid batteries, original engine and transmission. It still runs like new!

I have a 2015 Prius with 230k miles still on its original battery. So looking at about 25k miles a year. This car is amazing.
