Hi, I have recently purchased Honda Civic Ex 2004. It only has 200 mi on it. Couple of days ago, i accidentally left one of the internal light turned on for around 13-14 hours. Next day i tried to start it but it would not. in fact i was not even able to use key-less entry and had to use the key. My neighbour helped me jump start and i took it to a nearby pepboys for charging. I also asked them to check the conditon of battery (for which they also charged $$, so it was a professional check). They charged the battery but told me that battery was pretty weak and i should go to the dealer and have it replaced because obviously i still have warranty. I have 2 questions: 1.Is it possible that battery really became so dead that it needs to be replaced ? it was in a brand new car !!! 2. Obviously it was my fault that battery drained. would the warranty still be valid ? thanks kn
