second battery, Anyone Options

[Nemises]

Is their anyone here running a second battery in your car. If so how did you do it?

[C3L1CA]

I am

I have it wired up to an isolater so it charges both batteries but never drains from my main one.

[Nemises]

thanx yo

[mr_dude]

That put a strain on your alt?

[C3L1CA]

No it charges both like is only charging one. The isolater charges both batteries like it is only charging one. It is a nice thing to have. You can watch movies all day and still be able to drive your car.

My brother has two in his civic, but thats only because he has air compressors for his bag's.. and it helps alot, cause it can run when its off, an never effects his alt or engine, and thats a smaller alt an engine.

Why do you need a second battery? Only usefullness ive ever seen from it is when the 2nd battery powers a winch or something. If your having power issues beef up your alt and get a stronger cranking battery. otherwise the two batteries (being completely different batteries obviously) will just drain each other (if their connected at a common point on both + and -... Even at that if your alt's stock your prolly making the poor thing full field itself all the time or damn near close to it. poor idea in my opinion. Go percocet!

[Nemises]

for me 1 12 w7s/ 2 10w7/ 2 6x9's/2 5 1/4 / 4 6.5/ 4 tweeters/ 2 7 inch monitors and 1 4 inch monitor/ undercar neons and strobs. Dont want all this running off one battery.

You need a second battery to run everything else you have put in your car, like stereo, neons, TV, playstation. My lights don't flicker at all when my stereo is all the way up. It doesn't put any strain on my alt I don't just have them connected I have it running through an isolater which charges both batteries just not as fast, and doesnt put any strain on my alt.

sounds like a nice setup, i was looking at a 13 W7 the other day at a shop, she's pretty big, but why two 12"s and a 10" why not three 12"s or three 10"s?. also adding another battery will not help if you dont have a high output alt. to run all of this, them W7's will need power to perform well. you DEFINATELY need a high output alt. for this.

[playr158]

yo how do i do the 2 battery setup
i'mgoin to use yellow and red
red for car and
yellow for system
how do i set it up for the isolator thingy ect....

[Scarrell]

wire it in paralell

[FreddyTheOthaMea...]

Lemme know how many of you guys have battery problems in the future. I love being able to say "I Told you so".

[Scarrell]

yup me too Freddy, this second battery wont do any good if he doesnt get a high output alt like i said, he wont be able to run them W7's good unless he is puttin ATLEAST 500rms to each... and if he does that, with all that other stuff. he will need a highout put alt, of 140amps+ . then the second battery can be used, for your stereo, while the other is for the car. otherwise going down the road your alt will fry and your car could catch on fire..

It is not that hard I got mine at checker and it had directions in the box on how to do it.

freddy shut the heck up nobody is asking for your ignorance and crap....

for educational use

c3l1ca wat is checkers? like advanced auto?

and can you take a picture of the part cause i'm goin to be running like 2000watts RMS and i need the 2nd battery

[madmods]

guys go to soundomain.com forums for some more info on how to do this. I am going to run a second battery also.

[C3L1CA]

Yep checkers is like an advanced auto, they should know what you are talking about. I'll try and take a picture soon.

[bryce804]

this is playr158 (i work at advanced auto) i'm on my friend's screen name...but an isolator should be in the battery section no?

[Nemises]

So i should use a high output alt and isolator. Does anyone know if their is a high output alt for our cars. Ive also seen some bolt on setups for a second alt but i know they probably dont have that for the celi.

Oh and Scarrell Im not running all the same size because i really only planed on running 2 10 W7 but then came accross the 12 w7 for free so I figured i would throw that in for som over the top base. FYI this car is not my daily driver this year (showcar)

[Nemises]

anyone try the "STARTECH" brand i saw for sale on this site was wondering how it worked out?

[Scarrell]

cool cool, ummmm http://www.mralternator.com/alternators/toyota.html , they dont list the Celica but they have a pic of one at the top so, try calling them and asking. try some shops around town and.. maybe Jegs or Summit. im sure they have some. but i do KNOW there are highout put alts for Celica's of all years. but anyway i just dont want your car to really mess up with all that current being pulled, the reason i say you definately need a highout put alt is well because you are running alot of things and for them W7's to perform well you need quite a bit of power to them. and im assuming they will have that power, also i know where you can get a 10" W7 for cheap, just needs reconed and that only costs $155 from JL.

Heh ignorance and crap eh? If your HELL BENT on doing dual batteries make sure you purchase both batteries at the same time and are of the same make. Make sure to take all proper measurements needed to insure that they are as similar as possible. otherwise they'll leech off eachother and just drain eachother out repeatedly. I'd suggest just getting a gel type battery (more reliable and require no maintenance) and upgrading your electrical system (it would be a wise idea anyways incase of any shorting that may or may not occur. Be wise and most of all be safe.

[Seth6Gen]

Nemises, is your wind shield wiper broken? I only see one.

[van95st]

stinger makes a high output alt. for the 5s, don't know the amperage. It's pretty though if your putting it in a show car, chrome plated and all that. It's like $200 though. Don't know of any that make them for a 7a.

[Nemises]

no not broken pic was from my ricer days. There two wipers now.

Are you missing the part where they mentioned using an isolator? Because you sound like a dumbass right now. This is done all the time with high output sound systems and high wattage HAM Radios.

[Scarrell]

your isolator should be around 900 or more...

900 what?

[shid]

You need a second battery to run everything else you have put in your car, like stereo, neons, TV, playstation. My lights don't flicker at all when my stereo is all the way up.
[right][snapback]219082[/snapback][/right]

yeah.. yeah.. yeah..

Hmm, I've got all that, as well as a laptop computer, an SNES, an NES.

From time to time I turn all of that off and run mutliple 400W Tungston lights off my car.

and I don't need a second battery. Why do you?

How long does that work with your car off and do you ever worry about not being able to start your car. Granted, it'll take a while to run down the batterey but if you're at a show that stuff could be going all day.

[Mynzeyes]

We knew it was an issue and so we had jumper cables ready; but I ran 4 200W lights for 5 hours once and didn't need a jump- she started up fine.

The only cars I've seen that run power at shows are plugged in- and personally I wouldn't run power at shows unless I was plugged in.

I want them so I don't have to have jumper cables in my car. I am always showing my car off on friday and saturday nights, and when the cops come and kick us out I don't want to be like "wait officer I need to get a jump it will just take a second." I have a red top and a yellow top so I never worry about not being able to start my car
