How often do you change (or recommend changing) your car battery?
We are getting ready to take a trip to the beach (about an 800 mile drive roundtrip). My husband is concerned that we might need to replace our car battery. We haven’t had any trouble with the battery other than one time we left interior lights on for about 4 hours and drained the battery. We are uncertain of the age of the battery because we purchased the car recently and documentation for the battery was not included.
Given the history of our car battery, would purchasing a new battery be recommended before our trip? I don’t see any reason to buy a new battery at this point because we haven’t had any trouble with the battery other than when we left interior lights on.
Any insight appreciated! My husband feels we need to replace due to not knowing the age of the battery.
