If your battery is the original OEM battery installed when the vehicle was manufactured, it will have a Honda part number on it, and it will be rated for 410 CCA. Those are the easiest visual markers to check for. There should also be a date code stamped on the battery top somewhere which will tell you within a few months accuracy how long that battery has been in your CRV.
If you have a 2017 and it is the original battery, you are driving on borrowed time and should replace it. Your battery is already well past the life expectancy for modern motor vehicles. Which means it could leave you stranded at some point and will need to have it jump started.
Vehicle manufacturers these days when asked how long to expect the battery to last, the response is 3-4 years. Thing is actual life expectancy is all over the map due to differences in driving frequency, driving distance, ambient weather, etc. So one person might get 5 years out of a battery and another person will get only 2 years out of a battery. I have a series of stickied posts up top of this battery subforum that explains a lot of the nuance and details behind batteries and their life expectency if you wish to dive deeper into understanding.
