Why Your Fully Charged Car Battery Isn''t Starting:
Voltage Reading: A fully charged battery typically registers around 12.6 volts. You can use a multimeter to check this. Functional power windows, stereo, and other electrical features show that the battery is supplying adequate power. No Corrosion: Clean battery terminals without signs of corrosion suggest a well-maintained and charged battery.

6 FAQs about [The battery has volts but no power]
Can a battery have voltage but no current?
Yes, a battery can have voltage but no current. This happens in an open circuit. Here, the battery shows voltage, but no load is connected to draw current. Voltage measures the potential difference, while current indicates the flow of electric charge. Thus, a voltage source can exist without current under these conditions.
Why does my car battery have volts but no amps?
Another common reason behind a car battery having volts but no amps are bad contact somewhere between the rectifier and the load of the battery. You need to between the load and the anode bar to know if this is the case. If you see a drop in voltage when testing it, you can confirm that there’s a bad connection.
Why is my battery showing voltage but no amps?
If your battery is showing voltage but no amps, it could be a sign that your battery is not able to provide enough current to power the device you are trying to use.
Can a battery still show voltage?
A battery can still show voltage as long as it has not been drained or damaged. Open Circuit Voltage: Measuring voltage in a circuit with no load gives the open circuit voltage. The open circuit voltage reflects the battery’s ability to provide energy but does not indicate current capacity.
Why does a battery have no current?
No Current Flow: A battery may have voltage but not deliver current due to internal resistance or damage. High resistance can prevent current from flowing even if a voltage exists. No Load: If no electrical device is connected, the current remains at zero. A battery can still show voltage as long as it has not been drained or damaged.
Can a battery have good voltage and still be bad?
A battery can have good voltage but still be bad. Voltage measures the amount of energy stored in a battery and is an important indicator of its performance, with higher numbers indicating greater capacity.
