A good 6Volt battery will have 6.3 volts at rest. A good 12 volt battery will have 12.6 volts at rest. At rest means when the battery has not been used for a while not right after shutting it down. Cheap digital volt meters will not give a good reading on a running engine. I use a old Simpson 260 analog meter. (top of the line in its day) A good digital is very expensive (Fluke is a top line digital meter).
