Over the winter my 08 RDX tech had an issue of taking to long to start . I did a search on this site and found others had a similar problem. I took it to the dealer and they checked the battery and said it was putting out the 440 cold cranking amps it should. I was still having an issue with it starting now over the summer months.
My friends sister owns a Battery Store and i went to see her. She looked it up on the computer and the 440 cca is no longer the recommended battery. I had the battery replaced with a new 550 cca ( $ 70.00 ) battery. Guess what ? It fires right up . No hesitation at all !
