The car battery is what powers all the electrical parts of the car. It’s typically a rechargeable 12 volt lead-acid battery that powers the electrical system in the vehicle. This means that there are numerous chemical compounds within the battery that goes right into a reaction when it is in use. When it is recharging, the chemical reactions are reversed.
Automobile Battery Elements
The primary parts of the car battery is that it starts the starter motor and the ignition system. The starter motor is basically an electric motor that gets the main 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.
Everyone knows that when the automobile battery dies, you’ll be able to’t start it anymore. There might be many reasons a car won’t start, however while you hear that clicking noise, and no ignition, than it is probably a dead battery. The clicking noise is telling you that you 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 principle component 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’s the reason when you leave the lights on, the battery drains and you can’t get the automobile started.
So the next query is, how come the car battery drains so quickly which you can’t start the automotive, once you leave the lights on, however it can power 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 close to a full 12 volts to start your car. So should you’re battery is at 11.2 volts, sorry but you are probably out of luck. The second 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, through alternator belt, and produces electricity to recharge the battery. It’s like a give and take relationship. The automobile battery starts the engine, which in flip recharges it back up as it runs on gasoline. That’s why after you bounce start a car, you must probably run it for a while before you shut it off again.
There’s a little computer hooked up to the alternator that tells it to charge or stop charging the battery. That is an incredible little thing to have working because in case you overcharge the battery, you’ll be able to create hydrogen and that may cause the battery to explode.
So why then do you need to buy a new car battery sometimes? Well, because the batteries are likely to not hold the charge as a lot as time goes by. Most 12 volt batteries really hold near 13 volts. A mechanic once 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. However either way, it holds more than 12 volts. Then over time it starts to fade. And zuluf01 when it cannot hold a lot more than 12 volts anymore, than it’s time to get a new battery.
