Hi everyone I have just bought myself a Sebring Convertible 2,0 Diesel and I knew I needed a new battery - however there seems to be such confusion over what type of battery I need. The AA man says it needs to be a "Gel" battery - A Chrysler Parts guy says it needs to be a "Spiral Wound" and he also asked if my car had "Stop and Start" technology - Frankly I have no idea - please help
