I have a stock 2006 Civic EX and have about 40K miles on it. For the last three years, my battery has slowly died on me each year. I have no stereo system, no subs, nothing, bone stock. I don't understand why this relatively new car, my battery dies and i have to replace it almost every 1.5 years.

Also in one incident, my A/C adapter has melted my ipod cable. I don't know it has anything to do with it.

PLEASE HELP!!
