The automobile battery is what powers all the electrical elements of the car. It is typically a rechargeable 12 volt lead-acid battery that powers the electrical system in the vehicle. This signifies that there are numerous chemicals within the battery that goes right into a response when it is in use. When it is recharging, the chemical reactions are reversed.
Automobile Battery Components
The main components of the car battery is that it begins the starter motor and the ignition system. The starter motor is basically an electric motor that gets the primary gas engine going. The ignition system is what ignites the combination of gas and air to produce the combustion the engine needs to keep it running.
Everybody knows that when the car battery dies, you may’t begin it anymore. There will be many reasons a car won’t begin, however when you hear that clicking noise, and no ignition, than it is probably a dead battery. The clicking noise is telling you that you simply starter is working, but it’s not engaging the battery. When the starter is dead, you won’t here a clicking noise.
The automobile battery also runs the electrical system of the car. The primary element to the electrical system are the lights. The headlights, interior lights, trunk light, and the dashboard light are all powered by this 12 volt battery. That is why when you go away the lights on, the battery drains and you may’t get the automobile started.
So the next query is, how come the car battery drains so quickly which you can’t start the car, once you leave the lights on, however it can energy the lights for a seemingly unlimited amount of time while you are running the engine? The first part of the answer is that it takes near a full 12 volts to begin your car. So for those who’re battery is at 11.2 volts, sorry but you are probably out of luck. The second a part of that has to do with how it recharges itself as it runs.
How It Recharges
You automotive has something called the alternator. This takes the mechanical motion of the engine, via alternator belt, and produces electricality to recharge the battery. It’s like a give and take relationship. The automotive battery begins the engine, which in flip recharges it back up as it runs on gasoline. That’s why after you jump begin a automobile, you must probably run it for a while earlier than you shut it off again.
There’s a little pc attached to the alternator that tells it to cost or stop charging the battery. That is an amazing little thing to have working because when you overcharge the battery, you can create hydrogen and that may cause the battery to explode.
So why then do you need to buy a new automotive battery sometimes? Well, because the batteries are likely to not hold the cost as much as time goes by. Most 12 volt batteries really hold near 13 volts. A mechanic as soon as told me that they call it 12 volt batteries because 13 is an unlucky number. I don’t know if that is an urban legend or not. But either way, it holds more than 12 volts. Then over time it begins to fade. And when it can’t hold a lot more than 12 volts anymore, than it’s time to get a new battery.
