Why does my Car Battery Read 13 volts?
Why does my Car Battery Read 13 volts?
This means that your 12-volt battery can actually read as 13.2 volts instead of 12 when it is not fully charged. Most drivers never want to experience their car not starting or a bad battery. If you cannot turn on your car, let alone drive it to work or school, a bad battery, alternator, or starter are often at fault.
Why does my car not start when the Lights Come On?
As CharlieRB pointed out, just because the lights come on doesn’t mean the battery is ok. However, there are a few other things it could be. It could be that the battery is OK, but is not being charged sufficiently by the alternator. It could also be that the battery and alternator are ok, but that you could have what is called voltage drop.
Why does my car battery not start while running?
As of yesterday, will NOT start on battery. WILL always start when push-started (so far). While running, will stumble at idle with lights on, and voltage meter shows spikes when turn signal on. Initial Conclusion: The battery (via loose connection or ???) is somehow being isolated from the system.
What should the voltage be for a car battery to start?
Check the voltage when cranking the engine, if it drops below 10 or 11 volts the battery probably needs replacing. Also check the voltage when it is running, it should be 14 volts or more. If it is not then the alternator is not charging. You can’t post conmments that contain an email address.

Why does my car battery not work when I start it?
Starting the car is the single hardest thing (draws a lot of amperage) for the battery to do. If it is becoming weak, it will become harder and harder for it to crank the engine. The lights and other accessories may still work because they draw less amperage (which the battery can still support).
