    hi all, just looking for some input here... my 2010 is needing a battery soon, i've got 235k on original battery and am getting pa080 often... near me a 2010 prius w/ 110k is being parted out and i have the opportunity to get the HV battery out of it for $400. car supposedly is being parted out because a bearing in the 'generator' (?) went bad and the car would vibrate to the point of being undrivable... i would have to come pull it myself, which wouldn't be too arduous, but would really like to hear if anyone thinks $400 for a 110k HV battery sounds fair.

    assuming it isn't showing any signs of leaking or swelling, should i be jumping on this or more cautious?

    2010 is starting to get a little long in the tooth, but i suppose the price is right. it's a crapshoot imo, without knowing the history or being able to test, but if it's in decent shape, you should be able to get some good years out of it.
    if it fails, can you use some of your existing modules to repair it, or is that beyond your capability or desire?

    With the age and mileage, I'd be cautious. The price might be attractive but the HV battery could be a series of problems. If the vehicle's demise was an MG1 bearing it could lead to abnormal charging which could have damaged the battery.

    yeah, that is what i was afraid of... i am comfortable w/ rebuilding a traction battery and going through the process of balancing, etc. but that hasn't been an option as i need the car running for work, so no time to tinker w/ a battery on a bench.

    if i were to go out to get this one, are there any things i could be on the lookout for when examining other than swelling or leakage, considering the supposed reason the car died?

    About the only thing left would be to disassemble the cells and measure each for voltage. Variations over about a one or two tenths of a volt would be a concern. As @bisco pointed out, you could swap individual cells to rebuild your HV battery to extend its life.

    For $400 dollar thats a great price. Hell even bad batteries go for that! I'd snach it up. We've had very little battery problems form 2010's

    Mine started throwing P0A7F codes at 100k miles and as far as I read, it's because of the hot weather where it has been driven.
    From the lots of posts I read, the batteries don't like extreme ambient temps - too hot or cold, so if its life has been in a hot weather I won't buy it despite the great price.

    As Don said, you can check the individual modules after removing only one side of the bus bars, or use an app to check the difference between the voltage of the module pairs. Like Techstream for PC or HybridAssistant for Android.

    do you think you could open the case to look for corrosion and etc.?
