Extra Battery + Cap??

[Gir]

I have 1500w shuriken battery, and for my next system i was thinking of buying another one, however today i became the owner of an oldschool Rockford Fosgate 25 farad carbon cap for only $100!

What i'm trying to ask is, could i just run that cap with my extra battery instead of having to buy another one? I ask because i don't know how practical that would be or if it would even function properly as i've never heard of anyone doing it. Running that cap would save me about $200

Only thing its good for is nostalgia purposes,only caps that are worth a **** are maxwell banks.or the xs power ones but never used them.

I mean.. either way the only ones i can find for sale online are all between $300 and $500 and considering the condition i think i lucked out... but either way the question was can i run it with a extra battery lol

I actually agree with this my self lol, but if any cap that isnt a maxwell and isn't a low-end brand i'd consider fosgate a nice medium and for the price i paid i definitely came out on top. And hey.. it looks bad ***!

But the Rockford one is NOT the same animal, totally different internal technology.

A bank of 3000F caps will store enough energy to run a 1000W amp for about 20 secods, a 25F (assuming that's even honest) cap for under 1 second. The new super-cap technology stores about 40X the energy of the traditional style film capacitors. I don't know if either is even appropriate for you.

If people buy them, sell it for a small profit and invest in a battery or larger alternator.

Don't run the rockford cap. Use it as a paperweight.

Get another battery.

Can anyone provide a science as to why i would or wouldn't be able to run a cap and a battery at the same... Thats what i asked.. i didn't ask on a history lesson on capacitors that i already knew, I'm talking about the value of the cap being a score, even if it is next to useless on any serious audio setup.

If your married to the idea... just keep it as close to the amp as possible... people did it for decades...plan on adding a battery eventually tho... I had two batteries and when I added an AGM as a third battery it made a HUGE difference...

I do now plan on adding another 1500w battery for my next system regardless, but the cap is just to dope to not display until i re-sell it lol. I personally just never heard of anyone running a cap with an extra battery, always just one or the other.

You can run batteries and maxwell caps together.

The mainstream ones are trash though. Any capacitor on Sonicelectronix, crutchfield, ect. are shit.

If you already knew the history, you wouldn't be asking the question you did.

yeah if u want to spend $ get agm starting batt then a 2nd one later u can get them at advance for about $130-$160 order online save 20-25%, they still install it..

This.

With advances and such that we have today/now, typically a capacitor is worthless, although a cheaper alternative to another battery, than upgraded wiring for the big 3, a bigger better AGM battery and an aftermarket HO alt.
