Replacement Hybrid Battery Costs Plummet

2008 Toyota Prius

When someone on the EcoModder forums asks about buying a used hybrid, there is usually a flurry of excitement coupled with cautions about the age of the car and the price of a new battery pack. Ecomodders, usually being budget-minded folks, are very wary of the seemingly astronomical price of battery replacement.

In the early part of this decade, some of the biggest worries about hybrids were how could the batteries possibly last, when would they finally give out, and how much would it cost to have them replaced. These days, concerns about batteries have largely faded out of the minds of new car buyers. Honda and Toyota have both had hybrids on the market for about a decade now, and there are no ominous junkyards filled with dead hybrids.

To underline the reliability of modern battery-electric hybrids, Honda says that out of over 100,000 hybrids on the road currently, only 200 have needed out-of-warranty battery replacement. Toyota, on the other hand, has only needed to replace 0.003 percent of its hybrid batteries out of warranty on the second generation Prius. Granted, these cars still aren’t all that old, and the batteries will likely fail eventually, but it seems that they are living up to manufacturers’ promises that they will last the life of a car.

Necessity aside, Honda and Toyota have both announced drastic cuts to the cost of replacement batteries for their hybrids. It will now cost just under $2,000 to have new batteries installed in you Honda Insight, and just under $2,500 for your Accord hybrid. These are about $1,000 reductions in the cost. Toyota, on the other hand, has dropped prices from ~$5,500 to $3,000, but that doesn’t include the installation, so the real cost is likely a bit more.

So, buyers of used hybrids, never fear! It’s unlikely that your batteries will fail prematurely, and even if they do, replacements are getting cheaper.

Revising my message to you:
I double checked my info. I had 323,000 miles on my first car before the power pack went haywire. But, for whatever reason, it straighened itself out. I replaced the first car with the second one I purchased, because the first one was worn out. Anywise and from my experiences: the 2005 HCH DOES NOT require a power pack replacement at (about) 100,000 miles . . . at least neither one of mine did. Will it just quit running if you do not replace the power pack? I don’t think so. I have put 3,000 miles on my first car since the IMA light first came on . . . and it has never quit running on me. However, in checking back, my mileage dropped more than I thought after the IMA light came on. It dropped by 10 mpg or so. My advice: keep driving it. Yours may do what mine did. I still drive the high-mileage care today, in and around my home (a country boy). No insurance, no inspection sticker, no updated licenses plate . . . but the cows and deer don’t mind. Hope I’ve been of help.

My 2003 HCH has 137,500 miles on it and the IMA light came on recently.., a quick trip to the local service shop informed me I needed to replace the battery pack at a cost of $2,700.00!

Some research on the internet revealed a TSB suggesting Honda America has extended the warranty up to 150000 miles. As I passed this information on to my local service manager, she informed me the TSB was for the Insight model, NOT the Civic.., but she said she called American Honda for me and they agreed to meet me half way!! So I’m getting a new Battery pack next week for $1300.00 bucks!

This Honda Civic Hybrid car has saved me thousands in fuel cost over the past seven years as well as provided a comfortable, reliable ride along the way.

For me, $1300.00 buys another seven years of 48mpg efficency.., Its a No brainer!

I bought my Insight used about 5 years ago, a 2002 5 speed with 28K miles at the time. I would only get the MT since driving is a fun hobby, even in the SanFran Bay Area. I’m nowhere near a hypermiler, since time=money and 80 mph is a nice cruising speed when traffic permits. Anyway: IMA light went on last week, and it seemed the battery was less responsive, lost about 5% mileage. The dealer ordered a warranty replacement (64K miles now) 2 days ago. Today the IMA light is off (I don’t know why it turned itself off) & the battery seems to have more energy to dump into the motor mode, but I will still accept the “free” battery exchange.

From my experience working for a Honda Dealer.

The Hybrid system is considered by law to be part of the emissions systems. As such the warranty terms are determined by the law of the State you live in. Eight states have adopted the CA emissions standards; in those states the warranty is 10 years/150,000 miles. In the other states the warranty is 8 ears/80,000 miles.

Some people assume that means you will replace the batteries when they come off warranty. That logic doesn’t make sense. Your drivetrain warranty expires at 5 years/60,000 miles. Are you buyin a new engine and transmission then?

My experience is that the battery packs themselves are not the typical point of failure, but the charging systems. If the charging system does not operate at the right voltage the batteries can be damaged. I no longer have the TSBs but I remember that being the issue. I currently work with back up power systems that use batteries and improperly set charging currents can reduce the life of batteries regardless of the application.
