I just recently bought a new battery for my evo 9. Been in the car for about a month. My intercooler piping will not work with stock battery, so I just picked up a miata battery tray. I obviously need a miata battery, will any places do exchanges on batteries? I know with electronics, once it's been used it generally cannot be returned. But I dropped $100 on this evo battery, and to be stuck with it will suck. Especially having to buy another battery. What's the best option I have? Sell it to an evo owner?

 

Throw it on craigslist? It should be able to fit other cars, or save as a spare, use as a ghetto welding rig.

I'm in the same issue only with a mini battery. Still have the stock one installed since, I don't need to install the new uicp yet.
