Turn the multimeter on to the 20V DC section of the scale. (If you have an autoranging meter, just go to “V,” because you won't have a scale.) With the bike completely turned off, touch the black lead to the negative post of the battery, and the red lead to the positive post. Record the voltage.

How many volts is a bad motorcycle battery?

A meter reading of 12,2 or 12,0 volts will indicate a charge rate of 50% and 25%, respectively. Any reading below 11,9 volts will indicate a battery fully discharged, and storage device corruption may have occurred.

What voltage should a motorcycle battery sit at?

A fully-charged 12-volt motorcycle battery should measure about 12.6 - 13.5 volts between terminals depending upon its chemistry.

How do you check if battery is OK or not?

charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don't have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights.

How do I test my battery to see if it's any good?
