Today I picked up my 2005 V6 HondaAccord because I had had a strut replaced and I immediately drove it to a Jack in the Box which was about 15 miles away. I took the freeway and I drove my car at about 65 miles an hour. I ordered a hamburger, I parked my car at the store and stopped the engine. I turned on the radio to a volume 5. While I was eating my sandwich, suddenly the radio stopped. I tried to turn it on again to no avail. Then I tried to start the car but all I got is these flashing lights on the dashboard. The battery was dead. I am not sure how long I had the engine stopped while listening to the radio but it couldn't be longer than 20 minutes. Is it normal to run out of battery in such a short time???? I had to call Honda Care and they sent me a tow truck that jump started my car and then all was fine again. Can I trust this battery??? The car was bought Honda Certified one month ago.
