Is a Capacitor worth it?

[Stalin-ohaulic]

In the process of it now. Finding things like the following:
"Peak loads and prolonged idle conditions can result in battery discharge, since the alternator cannot keep up with the power usage. Idling for long periods of time with the lights, defrosters, heater, radio on can pull more amps out of the battery than the charging system can put back into it. You may think you have a charging problem, but there is nothing wrong with the alternator."

That definitely indicates that the battery is discharging and the alt's working to keep a charge in it, but high-draw applications such as audio will draw more out of the battery than the alternator can put back into it.

So how is it that you think batteries charge?

The voltage coming out of the alternator MUST be higher than the charge of the battery for it to charge!!! What does this mean?

It means that while the voltage of the system is higher than the batteries' charge it is charging and NOT discharging.

When the current draw reaches the limits of the alternator, the voltage drops to save the alternator. When it reaches the battery's charge, the battery begins to discharge. When the current is steady like this, the alternator cannot up it's voltage back to 14v+ and must stay below 12. The batt keeps discharging and since the alt cannot raise it's voltage it cannot charge the batt. That's all you just found out. You're actually helping to prove my point but you're not smart enough to know it.

Y'know what dude? I'm in here to see if I can figure out what's what in this situation, but you're not interested in actually getting information out there, you just want to wave a big flag that says "I are the smart man and you dumb". I wasn't even ARGUING with you, you putz, I was questioning something and trying to figure it out.

You must be a thrilling person to be with in real life. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

when you tell me something must not be right about what you're saying and you're trying to find something to prove me wrong you're being argumentative. I'm getting assaulted in here by a bunch of idiots that think they know but they really don't. I thought after your pm you would start to be slightly nicer and less argumentative. Instead you are still just trying to start things.

Here "The charging system in most cars will generally produce a voltage between 13.5 and 14.4 volts while the engine is running. It has to generate more voltage than the battery's rated voltage to overcome the internal resistance of the battery. This may seem strange, but the current needed to recharge the battery would not flow at all if the charging system's output voltage was the same as the battery voltage. A greater difference of potential (voltage) between the battery's voltage and the alternator's output voltage will provide a faster charging rate.

As long as the engine is running, all of the power for the accessories is delivered by the alternator. The battery is actually a load on the charging system. The only time that the battery would supply power with the engine running is when the current capacity of the alternator is exceeded or when engine is at a very low idle. "

You *****es all lose. Argue with them... and apologize to me.

Are you serious? Do you think a battery is necessary for the vehicle to stay running or something? I just don't understand what you think you're getting at here.

I found eCrack's blog:

I'm not being argumentative, dingbat. I said "something doesn't seem kosher". You said "look it up". So I did, and then tried to figure out whether what I was finding supported or refuted what you said, with no personal investment in either. I don't give a shit WHO'S right, I just want to know WHAT'S right.

You're in this thread calling everyone that disagrees with you an idiot and whatever else, lashing out angrily at anyone that doesn't bow down to your infallible knowledge. It's AMAZINGLY immature. Grow up. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

How about you let a bunch of people lie about you for a while? I'll admit I'm not handling it in the most mature way, but I've got to tell you that I don't really care. There is no satisfaction in acting humble when people try to call you a liar and you PROVE them to be liars.... I simply won't do that. You've all learned something today. Instead of attacking me and calling me names... thank me.

Dude, just go back to your own shitty board. Leave us neanderthals alone to stumble around knowing nothing. Your presence is not welcome.

Didnt even include an 'unless' scenario...

I hope you dont believe this...

You seem to have no idea about the relationship between current and voltage.

The statement above just proves what I said earlier about when your alt is charging at 50A and you need 100A. So you think the extra 50A would come out of the alt? Wrong.

Just because the alts current capacity is exceeded, doesn't mean you are under 12.6v.

And about running the car without a battery. Sure it will work, but very shortly your alt will burn out. With the batt unplugged, this makes the alt think its dead, now the alt is putting out max power which can damage electronics. This puts an enormous strain on the alt and will damage it quickly.

And about running the car without a battery. Sure it will work, but very shortly your alt will burn out. An alts output is not dynamic enough to change its output based on the load from the car. This means that if you remove your batt and let your car run. When you turn on the lights you are demanding instant power which your alt cannot respond to fast enough. This puts an enormous strain on the alt and will damage it quickly.

omg... I have PROVEN that I understand that relationship. I never said the extra current would come from the alt. When the current drawn is above the alt's ability, it drops the voltage and the battery discharges. I proved this with a link to a reputable site. You've already been proven wrong. Give up idiot.

Lol!!!! You know more than a reputable site? I've heard it all now.

The "unless" scenario is actually a sentence or two after the one you bolded. Learn to read and stop enjoying being ignorant so much.

Man alive, yea...didnt see that part, I was wrong (yes, I just said that...something you wont see too much from someone on ca)

And man, for someone who already bitched about someone doing the same thing to him...you sure dont mind putting words in other people's mouths (referring to you saying that I think I know more than that site...which I never said //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif)

But I do have a Q for you...you wouldnt havppen to be McIntosh just using a different sn, would you? You seem a lot like him arguing for the sake of arguing..
