Voltage Drop to about 7v when cranking.

Yeah, I saw a Fc the other day, that was having cranking issues, and it turned out to be a build up of corrosion between the battery post and the battery clamp. You couldn't se the corrosion on the outside of the clamp or on the battery, yet when metering the clamp, voltage would drop when cranking, while metering the battery terminal itself it showed held voltage.

If it is just the clamp, or the wiring connections, and the battery itself is staying high, then no.. it would not be a bad battery.
