Hi Tatenlyle.
I missed your last post. A fully or near fully charged battery should show 6,3 volts or more (an hour or so after charging) Few analogue meters are sufficiently accurate for batteries. Can calibrate against a digital one. If the cells have caps, very different gassing in one cell or a hydrometer will indicate one dud cell. Assuming your meter OK certainly seems defective. If sulphated due standing with low charge it would show charging volts notably above 6.5.
