My mechanic said they tested my battery and saw it has 366 CCA. The label on the battery says it has 500 CCA. The battery is about 4 years old and the warranty is 42 months so it's outside of warranty right now.
In any case, my car is still starting fine (for now) so I'm wondering if I should change my battery or I can still safely use it for now? What amount of CCA or what percentage of CCA should I replace the battery? I also am aware that winter is around the corner so I probably will replace it before it gets too cold and I get stranded.
EDIT: I drive a Honda CRV 2016. I can't seem to find online how many CCA I need and the manual doesn't specify, although apparently 366 is enough for now :D
