I have a 5yo Honda CRV. Recently I had two episodes when the car did not start after it was left with emergency flashers (hazard lights) on for 5-10(?) minutes. I had to ask someone to jump-start it (and it required an SUV for that; smaller cars, apparently, do not produce enough power).
What does this mean? Are flashers supposed to drain the battery this fast? Apparently, 4-5 years is the lifetime of a battery. However, I might have replaced it a couple of years ago (how do I find out whether the battery is the original one?) Could something else be the problem?
