Is there any maintenance we can do to make this battery last about 200-250000 miles other than going to the dealer. I've taken it to the dealer only for their 100 point check at 10 and 20,000 miles and the battery is one of them but all it says on the list is "CHECKED" sorry, I feel they should've charged it up or something. I've had fords all my life and have traded them in still running good at over 200K with regular maintenance. My girlfriend talked me into getting this vehicle and it is great we are averging a combined 42mpg but, this battery worries me i'm always thinking do I trade it before the warranty is up (8/100,000) because even a used one is expensive. This is something I never said to myself before.... thanks for reading my question and please direct me to another post if there is one similar to this
