I was still running the original battery and it would start even after sitting outside in the cold and snow for 5 weeks. That battery is still in the car when I dealt it.
I know, but you mention with the welcome lighting it went bad. What I'm saying is once I got a new battery with the welcome lighting on it can last a long time too. You might want to give the welcome lighting a shot again if you do like it (if you also have a new battery and that the one you have is not the factory original one since you probably would still have problems with welcome lighting on).
