I'm gonna be gettin one of them, and I'll probably only be able to choose an optima, not a brand that you can find online. my price limit is about 180 and i need it to fit in the stock position (i have a scion tC). i dono what the difference is between a red and yellowtop. im gonna have like 1200 watts rms from the stereo and i want to make sure it gets as much voltage as possible. the tC has a weak alt but i can't upgrade at this time, so i can only do the battery. i have to the optima because its the only one i can get at a store like autozone. if my parents saw me ship a batter to the house they'd freak, otherwise id look for stuff online. i dont need anything huge. i just want to choose the right one that'll do the job right. thanks for your help!!
get a yellow top over red. red top is for starting and yellow is deep cycle so it can take more abuse and it will start your car no problem.
dont expcet to be able to run 1200 with no problems by just upgrading the battery. because you dont have a HO alt and if you absolutly cant get one charge your battery after heavy bumping and around like once a week
Get the Yellow top if you get one. It is deep cycle and can crank the engine. But since it is deep cycle it has more resisitance in it so it takes longer for it to discharge. I would suggest a cap or two after the battery because they have very little resistance and can supply your amp as soon as it asks.
Where does it say not to use a cap after a deep cycle because of the resistance difference? Those articles are saying dont try and hide problems behind caps. I dont disagree that he is probably going to need a H/O as well.
I am saying that the amp draws faster than a yellow top can produce, that is where the caps can, and will.
tyler you make an upgraded alt? gimme the details and price plz, if any mods are required or if its a direct replacement, etc. i just found a kinetik dealer near me so im now considering them. which power cell would be best, ive heard the 1800 is good without going overboard?
Agreed on the Kinetics. In my OWN opinion Optima batteries are not worth the money. Both the blue and the yellow tops have a high internal resistance to control the flow of current, to provide a smooth longer lasting flow for special applications requiring it. With this said, the amount of available current is limited so it would take more batteries to get the job done. Both the blue and yellow requires a MUCH longer time to recharge than a standard fast release cranking battery. Kinetics are great batteries, fast charge and discharge rates much more suitable for our high current demands. Honestly if you need a battery with a large capacity, fast release and decent recharge rate get a standard cranking battery from Walmart. Polo...
