19.2: Electric Current
Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
12v battery reads good voltage but No AMPS
My battery voltage reads 12.7 volts stationary but when i try to start the vehicle it does want to turn over… I tried it with a new battery that reads 12.5 volts and it …

The first step in troubleshooting a car battery that is charged but not providing power is to assess the battery''s condition. A fully charged 12V car battery should have a voltage reading of around 12.6V when the engine is off and above 10V when the engine is running.
Not Enough Power
In my project I am running an LCD, Potentimeter, DHT11, Stepper Motor, and Servo ALL on the same 5V pin in my arduino UNO. Becuase the Servo is the last pin in order on the bread board, it isn''t going the speed I am coding it to go. Any suggestions on how to add another power source to another bread board row??
