Mike,

Listen to both 427 sharp and petek. I agree with them 100 percent........ if you cranked that long on the starter and still maintained 11.5 volts, that battery is doing OK. Even if the terminal voltage is down to 11.5, that is still sufficent to start and run the car. You might have lost one cell in the thing, but the remaining cells are up to the chore. At this stage of the game, you can plan on replacing the battery some day, but this battery is not going to make any difference in your "start and run" problem today.
