You can take your vehicle to an Autozone and they will test your battery for you.I have the 2018 CRV Touring. The vehicle is 3 years old. Having read several posts regarding the life of the battery I am thinking about having the battery replaced, as preventative maintenance and a peace of mind. I have not had any battery problems and wondering if it is reasonable to swap out for a new one before I do have issues. Your thoughts would be appreciated.
