Thread: Finding +and- on a cap

if you go with any secondary source use a batcap.

What is a BATCAP?

A conventional battery, as we all know has a positive and negative terminal. The chemical reaction within creates a flow of electrons, causing an electronic device (in this case an amplifier) to work. The stiffening capacitor is similar to a battery in that it stores a charge. The fundamental difference is it cannot create electrons. It can only store and supply (discharge) them upon demand. The advantage with a capacitor is that it discharges in one twenty thousandth of a second, unlike a battery that does in one second. The battery therefore cannot discharge fast enough to effectively supply the amplifier and this is the reason for "power sags."

WAKE UP! Don't fall asleep just yet, we're getting to the exciting part!

The XSTATIC BATCAP© is simply a battery that can discharge just a s quickly as a capacitor. Therefore, you have a constant supply of electrons that will discharge at lightning speed. This puts less strain on your stock alternator and battery. It also recharges faster than a conventional battery since the internal resistance is low. How about the install? Well I'm sure you can find a place to put this 2.5lb. baby and his 5lb. big brother. Don't let the size fool you though. These BATCAP's can crank your car, and you can bet we put that to the test!

The cost is another remarkable feature since the 300 model costs the same as a "High End" stiffening capacitor and the 400 model costs a little more. Remember, "good things come in small packages." (I was going to say that "SIZE" doesn't matter but, let's not offend anyone now.) Oh, by the way, the fact that the BATCAP© is capable of discharging in a RUSH over a 5-10 second period SCREAMS three letters, "SPL!"

batcaps are a good choice....A capacitor serves as a very good buffer for those sudden voltage drops hon hard bass notes. Its not the fact that your car doesnt have enough power for your system, its the fact your alternator has a 'lag' time in delivering the voltage so suddenly, so the alternative is to fall back on your battery, which runs at a lower voltage than your alternator, so you get the ligh dimming with the fluctuating voltage. (remember, your battery has a HUGE amount of current to deliver, but at a lower voltage than your alternator so you get the light dimming) A cap buffers this out by storing a large amount of energy at the alternators voltage, and discharging and recharging it very quickly iliminating the need to fall abck on your batteries current. Wise installers always say "the battery is to start your car and use electronics/lights with the car turned OFF..once your car is running it should serve NO purpose"

by you theory a cap will solve all light dimming problems. i have been a installer of car audio for well over 10 years now. in my wife's car she has a 600 watt sound system. by your theory, if i installed a 1 farad cap i would not have any dimming. because i would have 600micofarads for the system and a "extra" 400microfarads to use. WRONG. i did this at my former employer to prove to my boss caps are worthless. i charged the cap properly and then played a song at full tilt. my lights dimmed horribly a little worse thatn without the cap actually. i then installed a kinetik hc600 battery. which has more power than a 100 farad cap. i had no dimming lights at all.

Sabrewings, you are dead on.

Reinke: If you want to add more batteries go ahead. all we are saying is they run at a lower voltage than your electrical system, and put an enormous load on your alternator when you start adding additional batteries. Not to mention they are like dead-weight (50 pounds easy), they are not the answer for minor voltage drops in a moderate system, capacitors are used in all electronics (even in many cars alternators) to buffer out those brief and sudden voltage fluctuations. .. caps are not a solution to make more power, but when the power doesn't come quick enough capacitors fill the gap to avoid sudden voltage drop. Your free to add all the batteries you want, but that is not the way i was trained in mobile electronics, and from personal experience i would never add an additional battery to a regular system before an alternator upgrade (im not gonna call you a dumb ass, that would be pretty much un-called for )
