What should my voltage be for a good battery? What is a dead battery? Where do you measure the voltage?

What should my voltage be for a good battery?
The voltage of a fully charged battery is 12.7 Volts. Typically anything above 12.5 should be sufficient. Remember a new battery doesn't mean a "good" battery. We have seen a new battery with bad cells which renders the battery useless.

What is a dead battery?
A dead battery is 11.7 Volts or below. 

Where do you measure the voltage?
The best location to get an accurate read on what the system is 'reading' for voltage is directly at the power and ground terminals ON the Mixmate itself, not the battery/power source.
