Hello. I started a previous thread last week about battery tender times for the 360 modena. Now I just fully charged the battery with a battery tender (I charged it for 2 full days). The light was solid green meaning a full charge. I attempted to start the car today. And all I hear are the starter clicking noises and the car did not start. This is starting to piss me off so I decided to jump the car. I unscrewed the foot rest in the passenger side and got to the 360 battery. My garage people had a battery jumper so they connected it. I turned the ignition on and the car started! So I am assuming my battery needs a replacement right? Also, the engine sound was not the same. It sounded a lot deeper and muffled....sort of like the car was choking. And then the check engine light went on. Can anybody guess what is wrong with the car? I know I probably need to get it towed and serviced. Thank you.
