The car 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 various 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.
Car Battery Elements
The primary parts of the automotive battery is that it starts the starter motor and the ignition system. The starter motor is basically an electrical motor that gets the principle gas engine going. The ignition system is what ignites the mix of gas and air to produce the combustion the engine must keep it running.
Everybody knows that when the car battery dies, you can’t start it anymore. There will be many reasons a automotive won’t start, but if 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 partaking the battery. When the starter is dead, you won’t right here a clicking noise.
The automotive battery additionally runs the electrical system of the car. The principle part 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 leave the lights on, the battery drains and you can’t get the automotive started.
So the subsequent query is, how come the automobile battery drains so quickly you could’t start the automotive, when you go away the lights on, but it can power the lights for a seemingly unlimited amount of time while you are running the engine? The first part of the reply is that it takes close to a full 12 volts to start your car. So when 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, via alternator belt, and produces electricality to recharge the battery. It’s like a give and take relationship. The car battery starts the engine, which in flip recharges it back up as it runs on gasoline. That is why after you bounce start a car, you should probably run it for a while before you shut it off again.
There is a little pc hooked up to the alternator that tells it to charge or stop charging the battery. That’s a fantastic little thing to have working because should 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 automotive battery sometimes? Well, because the batteries are likely to not hold the cost as a lot as time goes by. Most 12 volt batteries actually hold near thirteen 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’s an city legend or zuluf01 not. But either way, it holds more than 12 volts. Then over time it starts to fade. And when it can’t hold much more than 12 volts anymore, than it’s time to get a new battery.
