is it bad to mix optima and stock batteries? I'm gonna do 2 yellow tops eitherway, would it hurt or help to run the 2 yellow tops + the stock battery (3 amps + air ride compressor) deciedeing wether to add the 2 yellows in the car and keep the stock batt underthe hood or just replace the stock batt with a yellow and then one more yellow inside the car
I hope that all makes sence... I'm having typing and thinking issues today hahahah
i dont see why not, they are still the same voltage.
If anything, id have a red top for just the starting and the yellows for the rest.
dont mix them just go with a yellow under the hood and one in the trunk, all batterys have to be new, same volt's, cca and all the good stuff or one will drain the other.
thats what I figured...
anyone know off hand the modle number of the one that fits under the hood without any modifiacation using stock hold down?
Yep, sweetnloud is right. Your main problem is going to be the alternator though. The amp draw is going to kill it, and it will then start taking out your new batteries.

you can mix them, just need an issolator so that the weaker one doesn't draw off the stronger ones. Batteries in each "block" should be the same and of similar age/condition.

how would a issolator help??? with the car on both battery's will be hooked up just like they will be with out an issolator. so that means it will do the same thing

maybe you don't understand how an issolator works. think of it like a one way flow control. you put the weak stock battery under the hood and the good stronger ones in the trunk. the issolator only allows power to go TO the batteries in the trunk so that the POS battery under the hood doesn't draw from the stronger ones and kill them. When the car is running, all batteries will be charging and everything will be running off the alt. BUT power will still not flow from the good batteries to the crap one. Should I break out the MS Paint and draw a picture too?

i hope you know current flows both ways, it is not good to mix batterys with or without an issolator.
an issolator makes it so you wont drain the battery under the hood with the car off, with the car runnin or whatever you wont have the same voltage for all the battery's and that will drain the battery under the hood.
also if you run the batterys in the trunk down then start the car you will put a vary large strain on your alternator to charge the batterys back up to 12 volts, and it will also drain voltage from the battery under the hood.
did you ever stop and think why no one uses them?? check out any one that does dbdrag racin or any other org. no one uses them because they do more hard for your ele system then good.

you're thinking of a RELAY not an issolator

nope im talkin about an iIsolator that isolates the first battery from the 2ed.
with the key on the 2ed battery is goin to be alot lower then the one under the hood and it will drein the battery under the hood, also the alternator is goin to work alot harder to bring up the voltage.
no matter what way you look at it both battery will be hooked togeather when the key is on and its goin to drain the battery under the hood some and also put alot more strain on the alternator.
i give up
