    If you plan to purchase a replacement battery I'd be happy to help point you in the right direction.

    People do some experimenting with rebuilding the battery packs themselves if they are technically included and feel comfortable working around high voltage. May not be too practical if this is your daily driver though.

    Feel free to give me a call 608-729-4082 and we can talk..

    ...this is a very old thread...but the $1200 would be consistent with getting a salvage battery pack from a junk yard Prius. The other low cost option would be to fix the battery by replacing the bad cell(s), but this requires some advanced DIY skills or willing mechanic (time consuming).

    I have been to the gentleman's shop in Scottsburg, Indiana. Autobeyours is the website, if he can't fix your 2nd Gen Prius nobody can. This shop has the knowledge and ability to do the kind of thing that has been described here. $4295 for a battery is steep, but changing it for a good used (balanced used) battery would be my call. $1000 to $1500 would be all that I would invest in a ten year old car, if it was my only choice. Without it, a Prius is a doorstop or a boat anchor. Yes, I love my '04 Prius and I would fix it, regardless. A good rebuilt or used would be fine.

    The battery is not going to be $1,000 unless it is some junkyard gamble with little or no warranty.

    Assuming that you install it yourself:
    A used battery is going to be at least $1,500 plus shipping.
    A new battery will be over $2,000, likely more near $2,500.

    Additionally, if you have a professional shop install it, you will need to pay them for a few hours labor.

    Well, with a pair of lineman's gloves and a good Fluke meter I believe I can locate the bad cell(s) in the HV battery. Tbe only thing that would stop me is the fact that I know that all cells have to be in balanced (relative voltage the same or nearly the same). So far, so good I have not had any issues with mine other than the inverter pump has died three times, all covered by Toyota. And the only thing out of the ordinary was the headlamp leveling sensor malfunctioned, turned on the "headlamp" on the MFD and again replaced by Toyota. So tell me if anyone out there sells individual cells for this battery or do they only want to replace the whole thing? The other question would be if I went to a junkyard and harvested my own used battery is there or would there be a way to charge it myself? Just curious, my thinking is if I did the labor I might save a buck or two. I am very capable of installing the battery, just want to conserve my money.

    You can buy individual an module (6 cells). Usually they are not tested or quantified. The real issue is that they will not be matched to the ones in your existing pack. You'll have a mismatch of both the capacity and the internal resistance. You can use a hobby charger to charge the module. The junkyard may not have any warranty on the modules.
    It can be done. But it takes a time and effort to do it right. And, as you can imagine, there are plenty of ways to do it wrong.
