The car battery is what powers all the electrical parts of the car. It is typically a rechargeable 12 volt lead-acid battery that powers the electrical system within the vehicle. This means that there are various chemicals in the battery that goes into a reaction when it is in use. When it is recharging, the chemical reactions are reversed.
Automobile Battery Parts
The main components of the automobile 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 mix of gas and air to produce the combustion the engine must hold it running.
Everyone knows that when the automotive battery dies, you’ll be able to’t start it anymore. There can be many reasons a automotive won’t begin, 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 simply starter is working, nevertheless it’s not participating the battery. When the starter is dead, you won’t right here a clicking noise.
The car battery additionally runs the electrical system of the car. The main 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 if you go away the lights on, the battery drains and you’ll’t get the automobile started.
So the following query is, how come the car battery drains so shortly you can’t begin the car, once you depart the lights on, but it could possibly energy the lights for a seemingly unlimited period of time while you’re running the engine? The primary a part of the answer is that it takes close to a full 12 volts to start your car. So for those who’re battery is at 11.2 volts, sorry however you’re 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 car has something called the alternator. This takes the mechanical motion of the engine, by way of alternator belt, and produces electricity to recharge the battery. It is like a give and take relationship. The car battery starts the engine, which in turn recharges it back up because it runs on gasoline. That is why after you leap begin a automotive, it’s best to probably run it for a while earlier than you shut it off again.
There’s a little laptop connected to the alternator that tells it to cost or stop charging the battery. That’s a fantastic little thing to have working because in the event you overcharge the battery, you can create hydrogen and that may cause the battery to explode.
So why then do you have to buy a new automobile battery on occasion? Well, because the batteries are likely to not hold the charge as much as time goes by. Most 12 volt batteries really hold close to 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. But both way, it holds more than 12 volts. Then over time it starts to fade. And when it could actually’t hold much more than 12 volts anymore, than it is time to get a new battery.
