I just got a brand new car battery about a month and a half ago. Duralast Gold for 2007 Honda Accord, 2.4L (4 cylinder). I also have 250W amp with subwoofers (MTX Terminator set). They never gave my battery a problem this early on. The amp is brand new as well. I realized yesterday that my car now hesitates to crank. (I will be getting checked when they open) I know itâ€™s cold and it may take a little extra to crank but not as long as itâ€™s taking. My spark plugs are also new. Maybe about only a year old. Another question, if my audio system is draining the battery would that just require it to be charged and not completely replaced? I need all mechanic opinions thanks.
