Curious what others experience is with battery life on LC and LX cars. I am wondering if the battery location in trunk away from the heat of the engine helps - heat is bad for battery life. I have the original battery in both my 2010 Charger and 2010 Challenger and no signs of any weakness (knock on wood). The Charger was a "B-car" - originally delivered in May 2010 - timing belt failed before delivery - new engine - car had only 250 km on it when I bought it in November 2010. So it sat a significant time - which is hard on a battery (sulfation). But I put the car on a battery maintainer whenever it sits for more than a day or so. The Challenger being summer only is on a maintainer more than not. So I am sure that helps. I have only once before had a battery for 10 years and that was a Delco battery back in the '90s. Quality of the battery may be another factor - though I have seen Mopar original batteries replaced in as little as 3 years.
