2007 Honda Accord. I was at the dealer a while back and they did multi-point inspection. They rate everything in colors so the battery was in the yellow and the description read that it was just okay not good which would have been green. I did my own load test with a battery load tester this past summer and it also confirmed that it was at the low side of good. This morning I forgot to shut off the headlights and was sitting with the engine off for about 20 minutes. I went to start the car and it was dead. Is 20 minutes too short to have caused it to die. I don't mind replacing the battery if necessary but I also don't want to throw it out if it has another year(s) of life in it. Time to replace it?
