best place to sell my old IMA battery?

[rpearson]

I have a new IMA battery (and that is a separate thread with that story), but I also have my old one. I don't have to ship my old battery back. I bought the GreenTecAuto battery on eBay from a 3rd party.

I emailed Revolt in AZ, and they will give me $200 plus cover the shipping. Is this a good deal? Or is there somewhere else I should sell it? TIA.
