well, as the title implies? My truck has always started fine and had plenty of battery power. I changed the plugs, started up and drove it. Next day I jumped in to go get some lawn mower gas and nothing.... I checked to make sure no lights were left on, the battery cables were in good shape with no corrosion, battery had plenty of water, etc.. Everything was on the up and up. I jump started it and the alternator gauge showed to be charging, I drove it a little while, pulled back into the driveway and killed it. Tried to start it again and nothing.

I have just never heard of a battery going dead without first gettin a little weak?
