Default What to do with good modules from defective battery?

I'm wondering what I should do with the good modules from my original, defective HV battery.

As many of you know, about a year ago I had to replace my original HV battery after Travis/Lormax diagnosed it as having a bad module following a persistent CEL. Travis helped me find an unused, A123 battery that was still in the crate. Once he had swapped the batteries, Travis said I had 2 options: store the original, defective battery in case I needed to break it apart in the future and use one of the remaining good modules should something happen to the new battery OR allow him to break the battery apart immediately and start selling the good modules for me. At the time, Fisker Automotive had gone dark but had not yet declared bankruptcy. Batteries were hard to come by, and no one knew if we'd ever be able to get batteries from A123 again. So I opted to just store my defective battery in case I needed it.

At this point, it looks like Fisker Automotive might be up and running and producing batteries in the future, so continuing to hoard a battery in case I need a module seems a little silly. I also wonder about the long-term health of a battery that sits unused for more than a year. It would be nice to recoup some of my investment in the new battery by selling good modules from the original one. But I don't know if there is a market for modules at this point.

Can anyone--especially the techs on the forum--give me their two cents?

Thanks in advance everyone!

Adam and I have plenty of modules to last a while(hopefully til they come up with a solution) but there is a market for them.

Thanks for the information, FiskerPhilly. Maybe I should speak to Alex at Elite Motors in Orange County, just south of LA to see if he knows more about battery modules here on the West Coast.

Do you have any thoughts about whether or not it harms an HV battery to just have it sitting in a storage locker, unused?

Yes there is some truth to that. As Adam and I have found out these modules dont like to sit for two+ years with no activity. Several have gone bad and wont accept a charge. I have started bench charging individual modules to maintain them. So in all likelihood your battery with one bad module should be dismantled and each module charged to max capacity to check them. This process takes quite a bit of time and requires special charging equipment that I had made. Adam now has it and Alex asked me about getting the equipment, but I'm not sure if he has it yet. Give him a call.

Actually you might be able to sell the whole battery with just one bad module . I actually have a customer that might be interested in it . His car has a battery in it that's worthless the car won't even go into ready mode . I also was contacted this week by the treasury department they sent me a Karma to look at and that car also had a none repairable battery in it .

The treasury department, as in the IRS? Did Fisker pay its taxes in Karmas?

Apologies for the late responses, but I haven't been reading the forum the past few days. Thanks so much for the info regarding the need to break up the battery and bench charge the modules! Seems like it is probably time to get that process started. And thanks, Harleyguy for the info regarding potential placement for my battery. I sent you a private message with my phone number...feel free to give me a shout to discuss any potential buyers.

I might be interested in a good used module or two ... one to use, and one just to have around.
