I have an 05 Double Cab with towing package and my battery has died on me. And I noticed that this batteries are under warrranty for 24 Months. The dealership said to take it in but with the battery installed on it. After they do a diagnostic they will determine if the battery is actually bad or not. I know the battery is bad since I took it to Checkers Auto and they told me it was done. But my question is that I have my Sirius radio hooked straight to the battery and my 750 inverter with a fuse line built into it. If I disconnect this items and take it in will that void the warranty or Should I fully hide everything so they can't tell I had something hooked up to the battery? Any advice please.
