    As many of you know my 2012 Prius C hybrid battery module failed at 115,000 miles.

    I took advice from the forum was able to repair my car using a salvage module from an LKQ in the other town.

    My question is: what to do with the old battery?

    I have the vehicle diagnostic report from the dealership, and still have the old battery. But I'll need to return it to get my $250 core-charge back.

    Is there any point in examining the battery to determine the failure mode?

    I've attached a photo of the report showing the voltage issue.

    There is a 2 volt difference between block v03 and v10.

    Rob,
    So you mean you have an entire extra pack consisting of all the individual modules?

    Or do you mean you just have one old module?

    I'm not clear if you replace the whole pack or just a single module.

    And on a related note...
    Would you be willing to give back to the community by simply checking in 2 times a year to give an update about the longevity of your fix? I know the community would really appreciate it.

    Rob, the battery pack is composed of many modules. You replaced the entire pack.

    I suggest either selling the old pack locally (probably to a independent rebuilder shop) or selling the individual good modules online (usually ebay). The latter will bring you more money but is way more work and time.

    The dealer said that 3 of the 10 battery blocks were "bad". So, I got a salvage battery from LKQ and replaced the entire "pack".

    That's what I thought based on your other posts, but wasn't sure.

    There may be a local recycler that will pay cash for the pack.

    Look for industrial battery recylers. Ask a local junkyard that sells Prius parts.

    ..you can also use some of them to jump start or support a 12V battery. I have tried that before on either a hybrid of conventional vehicle

    Rob, if I were you - "you replace the whole pack" - I would return the whole old pack and get the core $250, if they're still offering it. If the pack's been sitting 1-2 years, parts of the pack may be damaged/drained, though maybe not...

    In actual fact the pack is 28 modules in 14 blocks. You probably have 3 or 4 bad modules. The rest of the modules are worth $15-45 to someone. I even sold my 5 bad modules to someone for a couple bucks -- God love the person that manages to fix a bad module -- I certainly couldn't figure it out. On the other hand a bad pack is straight forward, if involved, to fix by substituting similar good modules, discharging and charging several times, rebuilding the blocks, balancing the overall pack. I bought 6 used but OK modules and have 6 months on the rebuilt/rebalanced 2004 pack so far...

    i believe the regular prius is 28 models in 14 blocks and the C is 20 modules in 10 blocks?

    How is your Prius C hybrid battery doing to this day?
