I am unable to charge my 2008 Roadster with the timer. I have been charging it manually for the last two or three years. While charging it recently it overcharged and I was then unable to move the car for a couple of days. I took it in for a repair estimate a couple years ago and they said I had to replace the battery because a part had failed, causing the problem with the timer. I don't remember the name of the part but I think it had a three letter acronym? Any idea how long I will be able to continue to charge the battery as is? I was thinking I could by a 240 volt timer to do the job. I don't see why that wouldn't work? I'm getting ready to sell the car and I think whether or not the car can continue to be charged as is could make a huge difference in its value.
