    If you keep your Gen2 Prius long enough, then given your particular driving conditions, how long would you honestly expect the hybrid battery to last?

    Good to see some optimistic votes. :)

    I only selected 150 to 200 k-miles.

    My friend who was an early adopter and got his 2004 in late 2003 as one of the first delivered here in the NE still has it with over 225,000 miles on it. No reason these batteries should not last 250k+. Taxis have already shown it is quite do-able.

    I do pay attention to SOC on long downhill descents and use B-mode to prevent overcharging the battery, and leaving the car parked with windows slightly cracked open on hot summer days so the temperatures in the cabin doesn't build up to ungodly levels as the car sits in the sun.

    Figure these things will keep my '07 Prius HV battery happy and healthy past 150,000 miles.

    Yep, but unfortunately were I live there's lots of hills and plenty of heat. I think the traction battery will wear out faster under these conditions. So far it's only done 92000 miles (had done 41000 miles when I bought it S/H) and already I think I can notice the battery is slightly weaker than when I first got it (at 41k). Having said that though, the battery is still in pretty good shape. I honestly don't expect it to die real soon or anything. But I wont be surprised if I see a gradual decline in battery capacity/performance over say the next 100k miles, and with this a somewhat increasing probability of outright failure.

    I hear you but I still think you're good for 200k plus, and very possibly good for 250k plus if you choose to keep your car that long.

    I've got 198,000 miles on my 2005 so far. We went to the dealer to check out new priuses, and was told we could expect at least another 50,000 to 100,000! I will keep my fingers crossed!

    1) I do not think it depends on the number of miles but on number of summers, so being a long distance driver means I will get more miles in fewer summers.

    2) The more your Prius is in use, the more time the computers are coddling your battery, so never taking any days off driving means my battery is coddled every day.

    3) I know it has lasted 93,000 miles already, so there is no point in guessing under 100,000

    200K already on original HV battery. I am hoping for 250K+ but would still be hapy with between 200-250K since I can get a replacement installed for about $1200

    The traction battery in my 2004 died at 147k miles. I traded it in for a reconditioned unit from Re-involt. Did the work myself (it's quite easy) to save some cash. Though I was pissed it failed so early. I was accustomed to my 4-Runner, whose only major repair was a clutch replacement after it hit the a bit over the 200k mile mark... and that was only $300 to replace clutch, flywheel, etc with a TRD kit.

    Hi all--

    I use the ScanGauge's SoC meter and make a conscious effort to keep the SoC as consistent as possible - generally right around 60%, or 6 bars if you don't have a ScanGauge. I almost never let the battery drop down to 5 or even 4 bars. I think cycling the battery as deeply as possible is what wears it down.

    I've got a friend with a 2004 at 210k and he drives his like crap. And the battery is still going strong.

    I'd hope I can get 250 or more out of mine. At about 25k miles/year, that will take me about another eight years.

    Yeah that sounds like a good plan, your battery should last forever. :)

    I also try to keep my SOC fairly consistent, but I still get a lot of hills were I just cant avoid large SOC swings. One change I have made to my driving habits is to add a very small warm up (often just 30 to 40 seconds in "P") and it really helps keep my SOC more consistent at the start of a trip. Previously I used to find that the SOC would drop to 2 or 3 bars in the first few minutes when the engine was cold. Now it rarely drops below 5 at this time.

    I have to confess however that sometimes I just cant resist gliding a bit too long in EV mode, and sometimes I run it down to 3 or 4 bars. But I'm trying to resist the temptation. :p

    our 04 with 95,000 is up for sale. it runs like brand new and still gets 55-65 mpg. it has had gentle driving, a reasonable climate, garaged parking and not much in the way of big hills. barring any defects, i think 2-300,000 miles is not out of the question.

    Mine lasted 270K miles before replacing.

    Mine died at 148000. No reason given; sometimes they just go bad. $4275.00. Originally to take a week to get the new battery from the west coast. Now the end of May at the soonest.

    Hi frizi56--

    It may be a little late to change your mind especially if the money's already been charged, but with 148k miles you could consider a salvage battery? I'd just think you stand a good chance of a brand-new HV battery significantly outlasting the rest of the vehicle and I'd hate to think you'd plunked down enough for a decent used vehicle on just a battery. Since you're in the Midwest, I'd suggest this guy. About 3/4 of the way down, you can get a salvage battery for $995..

    Edit: I should clarify he's in Indiana - depending on where you are in Illinois it may be worth a shot taking a drive rather than waiting weeks for a new battery.

    If PriusChat member JDenenberg could not get to 200,000 with his first battery, I do not think I can either. By the time I get to 200,000 my 2006 would be 10-yrs old and I'd bet dollars to donuts there is some corrosion on the terminals and other parts.

    First of all, corrosion has NOT been a serious problem in Gen2 or later Prius batteries. You live in a cool climate and the odds are that you will get 200k or more out of your HV battery. 27 of my 28 modules were still in good shape at 195k miles and 8 years of use. One Module suffered enough imbalance that caused a cell reversal when the Battery was discharged to 40% SOC which was just one point on the probability curve for these batteries.

    kevin,
    what type of mechanic can fix your battery pack for $1,200?
