I had a battery I bought new in the spring do that to me all summer long. After about the 3rd time, I took it to an auto parts store to have tested and they said it was fine. Then I thought it was something on my boat causing it. I fought it like that all summer but I never did actually have a dead battery. A few weeks ago, I pulled my battery and brought it in the basement to charge and got the same error message. I took it back to walmart where I purchased it and they tested it and it came up bad. The guy at walmart said that walmart just switched to batteries made by Johnson Controls instead of Exide and that wasn't an uncommon problem with Exide made batteries.
