ps- ive read almost all the threads but this is a bit specific to red vs yellow and the amp situation being right there next to the batt. along with the fact that this is not a full competition sound system....

well i think i just answered my own question but we'll see what you guys think

 

hey if you dont mind, could you give me a place where you found info on relocating the battery?? i already have a red-top optima from a maxima i use to own an would like to use it again. sorry for not answerin your question.

P.S. i would say buy the red, longer warranty an you dont have a competition system like you said.

 

So optima says that the yellow would be better. Well, ask yourself this: does the yellow cost more? If yes, then it's probably just a marketing scheme. If the red is powerful enough than it'd probably work just fine. Plus, it's got the longer warranty.

 

yellow will last you longer if you shut down your car and crank out the music. it has more "reserve juice" in yellow than the red.

 

so thats the difference ("reserve juice"), i never knew why the yellow was more

 

battery relocation can be found here with a search
its not hard at all if yo think about it-- you can also find it with yahoo-- millions of sites based on cars...

as far as marketing-- yeah i know but the yellow is said to be geared more toward sound system and extra electronics which i have a lot of in the car
1) kenwood lcd, motorized dvd/tv/tuner/cd player
2) satellite radio
3) amp and 12"
4) apexi boost controller
5) 3 apexi (el2) guages with control box (lighted)
6) reverse indiglo guages
7) msd ignition (6a)
8) turbo timer - with A/F and batt reader (apexi)

so with all this said im running alot of 12v stuff here-now what do you think...

 

ah, okay. Well, if I were running all those electronics I'd probably go with the yellow. Especially since I'm always sitting in my car with the radio on when it's off.

i agree wit him on that, and i do that too when im at home an bored outta my mind

 

so everyone here thinks yellow is better but not really much reasoning unless im using it without running the car??
I dont really do that - unless you think the electronics will draw too much off of it and cause increased stress and drain??

 

yellow top all the way... in addition to its pretty much the most powerfull and hold the most "juice".. comapred to the Red and the Blue top

 

so it can hold more juice?? i dont get it i thought all batts put out 12v and xxx amps then recharged by the alt when they go low--

 

The yellow top is classified as a deep cycle battery. Deep cycle batteries can be run all the way dry (about 10.5 volts) of charge and be recharged safely. They're usually for trailers, and other motors that usually run off just battery.

Non-deep cycle batteries have a tendency to bend the metal plates inside causing it to short the battery (sometimes explode) if you dischrage it completely then try to charge it again. Ever try to charge a completely dead car battery?

If you've got a lot of audio/video stuff in your car or you're a dumbass who leaves their lights on all the time then you'll want a deep cycle. My choice would be the yellow. It's a little more money but I think it's worth it. If you don't have much in terms of electrical components to drain the battery then go with the red top.

Good stuff here! The Yellow Top battery was actually first made for off-roaders. Since winches would use so much power, regualar batteries could not get the job done effeciently. With the technology of the deep cycle, people with anything aftermarket on the car that requires more power, can use the yellow top.

The red top is stil a dry cell battery and can be discharged and recharged unlike a regular battery found in most cars. However, the red top is their "starter" battery which means it is meant to push out the CCA and amps it takes to start up your vehicle.

Both will work just as good, but if you intented to run aftermarket electronics, a yellow top would be the way to go.

 

thank you for the info...
my stock batt can still perform the duties i need it to for now- i dont see why to change at this time but i plan on relocatting to the trunk for room up front and i read that because of fumes in the trunk I should use a dry cell

although some believe that newer technology batteries dont have fumes. any idea on that-- some threads i have read -which will obviously be no different than this one all opinion. but note that todays batts dont have fumes from the sulfuric acid

 

From optima site:

Does OPTIMA ever Gas?
When used with a properly regulated constant voltage charging system (such as an alternator) the OPTIMA will usually not emit hydrogen gas. However, gassing can occur when charging at higher voltage levels or in extreme high temperature conditions. In automotive applications this typically will not happen if the alternator/regulator stay below 15 volts.

Basically if your alternator isn't messed up and you take care of the battery you won't kill yourself from having the battery in the trunk. Optimas are no spill. They're sealed as long as you don't try to jimmy open the lid.

 

that is for the optima-- i meant for everyday off the shelf batts.

i can see that the yellow is better but i still cant see myself spending 140 for a batt that may only last a year- (why dont they wty it more?) they do for the reds-- this to me means that
1) either the yellow isnt as reliable OR more likely
2) that people use these for sound alot and optima wasnt going to take a hit warrantying 10 mil batteries

i think the yellow is better because it will support more elecs..... but my stock batt does that now and as long as i dont leave the lights on im good-- no need to get a new bat unless i HAVE to relocate it- which i do.

 

I'm in same situation...looking to relocate battery to trunk and I don't runa lot of electronics. I want to make room under hood for a catch can. Autocross is my thing so stereo/video just adds weight...

 

yeah i believe the fumes issue is not really an issue so much now-a-days because BMW's have had batteries in the trunk for a while now and like you said most of todays batteries dont give off a noticable amount of fumes.

 

Ive herd in a couple of places that optima batteries aren't the best for sound systems. There are better performing batteries.
