It does seem like this factory battery is a pathetic POS though.........I think it only has 500cca.
Chris, you might want to look at this thread: http://dygytalworld.ehost-services13...read.php?t=259 In post #4 I talk about what I discovered regarding current draw on the battery by my 2005 truck. If the battery is weak or it's very cold, I think the symptoms would be exaggerated.
