@Moving Right Along What are the chances of getting 7 years out of that battery and what are the chances of it going bad in a year or two ? If I keep this I will live in fear everyday . If i return this and get a civic/corolla in almost same price I will not have to worry for the costly battery repair. @jerrymildred what is the prolong grid charger and can I use it on my own. I do not have much exposure on the technical side of the cars.
As to how long your particular battery will last, there is no way on earth to know the answer. Worrying about it makes absolutely no sense. Sure, you could get a Civic or Corolla, but what if the automatic transmission fails? That cost way more on my Intrepid than the battery for my wife's '07. Perhaps there's a 900 number you could call that could tell you what to expect. There are scores of threads here about the Prolong charger. Just do a search and you can read for a week. Here's a link to their web site. Prolong Grid Charger Product Guides – Hybrid Automotive And, please, stop worrying. It's not good for you. All cars will break if you drive them long enough and the Prius is arguably the most reliable car on the road. People obsess about the battery and ignore the other expensive repair items that come up just as often.
Like @jerrymildred said, there's no way to tell for sure. A little knowledge can be a dangerous thing if it leads to lots of worry. I did a LOT of research into battery failures when I was looking into buying a Prius, and they're fairly rare - typically less than 1% in the first 10 years, and then 3-15% after. The odds you'll need to pay for a repair costing over $1000 are the same for the Prius and the Corolla, according to True Delta. It's true that a Corolla will be an exceptionally reliable vehicle, but so will a Prius! And more to the point, you found a car you like that's going to get you better fuel economy than a Corolla ever could. I guess what I'm trying to say is: don't get rid of your car because you found something that's not actually a problem. You're not going to find a used Prius with a perfect 100% battery, and just because your battery is half its maximum capacity doesn't mean it's on its deathbed.
I feel like a complete moron. You apparently WANT everyone to tell you the HV battery is going to be an immediate problem. My recommendation is that you get the Corolla or whatever you plan to get. You are obsessing entirely too much about the battery. You asked for advice about the graphs. I told you the graphs look pretty good. I showed you the graphs from a kick-nice person battery. Yours are not all that different, in the big scheme of things. The load graphs you supplied tell the story, not some load test using a stopwatch, based off a few experiments, where you have no idea what the actual current load is.
I respect every forum member advice and appreciate for taking time to respond to my questions. $9K is a lot of money for me and I just want to make sure that I don't get any costly repair at least in next 18 months as I will not be able to get it fixed...a little tight on money . I know I am obsessing too much about the battery
No costly repairs in the next 18 months, huh? I wouldn't necessarily count on that, depending on what you mean by "costly." I just had to replace the front brakes on my Prius for $340 or so. My first year with my last car, a 2007 Corolla, I needed to replace the intake manifold gasket for roughly the same amount. I'd budget at least $500 a year for car repairs & maintenance, even for a reliable car. I wouldn't expect repairs costing thousands of dollars, but you'll probably have to spend a few hundred each year, even if it's only for scheduled and preventive maintenance.
if you take cabs and busses everywhere you never have to worry about repairs .. or you can buy a magic 8 ball, they can predict the future as well as we can on a 10 year old used car.. some people just confuse me .......
I have finally decided to keep the car . A big thank you for all who responded to my questions. Really appreciate your help and time. I will post some pictures of my car tomorrow morning
Hope you enjoy the "new" car. It will almost for sure be just fine. As for making sure you don't have any costly repairs in the next 18 months, @Beachbummm has the only viable suggestion. There are warranties, but there are no guarantees, if you get my drift. Drive it, enjoy it, and save up for repairs just as you should with any car.
Just wanted to let you all know that my "new" prius is running great so far . I am getting 50 MPG of average..YAY. Here are some pictures -
I'm getting ready to give my daughter my 2008 w/130K miles, and am confident that it has many more good miles - car and battery. Posted via the PriusChat mobile app.
Wao! I think your pack is still in good condition, but I'd put an eye on block 5, just in case it develops some problems in the future. The plots on the graphs, look pretty tight, and close. Those are my opinion though
Thank you Dxta for taking a look at my battery test results. The car has been running GREAT so far and I am getting 50MPG regularly I am planning to run the battery test in few days. Will definitely keep an eye on block 5.
Congrats! Just to reinforce what many other members have already told you: I have a 2007 with 200K+ miles. The HV battery's still strong, routinely in the blue range, often green, almost never purple. Still getting 48-50 mph overall. Enjoy the car and the money you'll save.
Are you also using the torque app to generate those data you posted here? Here's a sample of the app. Pls confirm, if it is. Would want to purchase today. Or is this one different from the one you used? Thanks
