    There is a local guy who has a prolong charger/discharger for sale for 3rd gen prius. My car, 2013 Prius V has 190k and still on the original battery. I purchased the dr prius app but have not done the battery test just yet. I have never had any kind of battery error and my two last tanks of gas averaged 49.9mpg and 48.0mpg so i feel like the battery must still be strong but wondering if I start using the prolong if it would be worth it. Hes asking $450 which is a fair amount off retail, or should I just wait and put the money towards a new battery when the time comes?

    If mine were already 10 years old I'd just start saving for a replacement battery.

    You cannot really recondition a 3rd gen battery (2010 to 2015) and expect a long service life. That generation is much harder on the battery than the previous generation (which you can successfully recondition). So my suggestion is not to waste your money and use that money towards a new battery when it fails.

    Yes I made the mistake of buying a pretty nice grid charger the Venice hybrid setup both pieces the discharger and the charger itself it has settings for Honda Toyota and so on and so forth batteries It's a nice setup and the guy who makes them can make them configured in certain ways I wanted mine with all the switches and buttons down one side and the display on top so it can stand up on its end without falling over that was an easier request in the guy was like no problem shipped to me in 6 days I've used the thing maybe one time because when your battery starts getting up in age 10 years around that It seems to me that there's usually other damages starting to happen in the battery case just because of age and or mileage and then I wind up doing lots more or changing the whole battery rack itself so my nice charger spends a lot of time sitting and I have five or six Prius vehicles all with the same battery style like yours with your car getting 49 and a half miles to the gallon and being a Gen 3 I would pray and be relatively quiet because that's not too bad aren't you at 13 years now or something so reality is you're falling in the range of when Toyota and battery people say that the battery should start heading south time wise. Because you're not at the mileage well that doesn't really have much to do with the battery that's just your use or not use of the car to make everything last maximum in a Prius as far as the battery and all that goes these cars need to be in the wind so people doing delivery work Uber eats stuff like that these cars seem to do real well I have a 2010 solar roof car with 365,000 mi on an original junkyard battery because the one that came with the car was corroded to death bus bars and nuts etc. So really it's a Toss up. If playing around with the batteries and that sort of thing interest you and you want to learn something about it then the 450 might be worthy of your time but generally a $500 tool should get some use. And if you're an HVAC school or studying to be an intangible assets guru or something like that this type of stuff may quickly not interest you.

    The system for the "V" (wagon) is different from the regular Gen 3 system.
    You need to go to the Prolong page and see which one fits your car.
    If it is the one that fits your car, it will be worth it. Make sure you get the harness that attaches
    to the hybrid battery or you'll be paying $150 for it. And if you have to do that, you might as
    well get a new one which comes with a warranty.

    You want to use it BEFORE you start having issues. Like you change your oil and filter BEFORE
    the oil wears out and and you burn up your engine.

    Can you please explain this to me in more detail. The battery modules are the same between Gen 2 & 3, so how is the Gen 3 harder on the battery than the Gen 2?

    The cooling is the main reason the 3rd gen battery is inferior. The 3rd gen battery runs much hotter and deteriorates to a point of no return when it does fail.

    It's BEST if you use this BEFORE your battery declines.
    I had noticed was staying at the 2nd bar a lot longer before going
    to the 3rd bar, then it went to the 4th bar a lot quicker.
    The engine would start after being at the 3rd bar for a short time and usually
    it would drop to the 2nd bar right after the engine started.
    After my first use of the Prolong system, everything went back to being smooth.
    For about 10 months. Then it slowly started doing what it had done.
    So I used it again. I've used it 3 or 4 times and it's been 8-10 months.
    Except for the last time. It was about 7 months and all was fine but I wasn't going anywhere
    for about 4 days so I decided to run it while I had the opening.
    7-9 August, 2021 is when I first used the Prolong system.

    Cleaned Hybrid Fan and housing, really wasn't dirtly.
    Cleaned Bus Bar and Nuts on the rear of the battery, the really weren't dirty either.
    Charged battery, Discharged battery, All 4/3 cycles
    I had 243850 miles on it, original hybrid battery.

    I now have 317,700 miles on my 2010 Prius.
    This system certainly has worked for me.

    Hey guys, I have a like new Prius hybrid battery, bought directly from a Toyota dealership in September of 2022. Installed and driven only 6,000 miles. Tested at over 96% original capacity. Ready to install and fully assembled, includes all battery casing, mounts, screws, wiring, and the battery computer control module (Toyota sells just the battery insides and requires assembly). Recently pulled out of a 2008 Prius that was in a drivers side side-swipe accident and still drove perfectly fine after the accident. Battery was $3,300 MSRP and didn’t include all of the above-mentioned items. Receipt available, asking $1,800. Located near Berea Ohio, local pickup only. Private message or use Facebook posting link for contact. Facebook link

    Gen3 and Gen2 Have identical batteries but Gen3 has a more powerful gas engine and more powerful motor-generator, thus Gen3 will be a lot harder on the battery pack than Gen2.

    Dr. Prius Battery Life expectancy gave me 57% - 2013 w/ 111,000 miles. Bars are still green on the battery monitor in app and I still get the same mpg I got when I bought this three years ago. ...How long do I have?

    It's like you've just had a doctor's appointment where you learned something important about a serious illness. Shock, confusion...

    Small voltage delta between 9 and 10.
    In fact, there's nothing to worry about.

    Try the Hybrid Assistant program. It's free, but its reports with tables and graphs are more informative about the dynamics of the car's operation and the state of the high-voltage battery.

    No one can tell you that, they can only guess.
    You should purchase the Prolong Charger/Discharger and run the complete circuit.
    It will prolong the life of the hybrid battery. I got almost 3 more years for mine. I probably
    could have gotten more, but I didn't want to take the chance beause I would get the check hybrid
    system alert when I had just 2 or 3 bars in the morning, and drove off right after starting the car.
    If I waited for the engine to start, then waited a minute to charge up the battery some then driving.

    I was able to clear the code with my D8, then let the battery charge up for 30 seconds or so and
    slowly drive off. Then it was fine.

    UPDATE:
    It won't help every battery. But it won't hurt. If you wait too long, nothing can help the battery.
    But like changing the engine oil, you change it BEFORE it fails to keep the engine healthy.
    Since you are not having any issues with YOUR hybrid battery, now would be a good time to
    use it to KEEP your battery healthy and lasting longer. Keeping it balance seems to be the most
    important part.
    As I stated, it worked for ME. And it's worked for others as well. It's an investment. And you can always
    sell it after using it and recoupe most of the money you spent on it.
    There are other systems out there that are suppose to do what the Prolong system does, but I've
    never seen them so I don't know if they work or not. But going "CHEAPER" is not the way to go.

    It was worth it for me because I didn't have $2500 for a new battery. So $700 was in my budget.
    It gained me almost 3 years, so I could save up for a new battery. But they toyota wouldn't sell
    it over the counter any longer. And new cells were still $2500. So that's why I purchased the
    lithium one, it was about $700 less. And I'm very happy with it.

    No the prolong won't make really any difference I have one of those fancy Venice hybrid chargers sitting right here on the floor It's been used like twice so basically it was not worth the purchase I have it here in the discharger too I have never had to use it I did use it once just because I wanted to and that was that now you can bill these things for 130 bucks you'll probably never use it you'll connect it up to see it work and do its thing and then you'll be like okay next. I would say run the crap out of your car drive it like you stole it like you need to whatever it is you're doing and when it's time to mess with the battery mess with the battery like your flashlight You go to the CVS and you buy four new batteries for your mag light and that's that when the Prius battery dies you go to the store and you buy a new hybrid battery and you screw it in the hole and you connect the wires and then you forget about it for the next 8 years generally speaking unless you just like worrying or something.
