Except they do not recommend the Reds for winches they will not even warranty them if they were used for that. But the yellows they will http://www.optimabatteries.com/optima_products / YELLOWtop/index.php
I have never had any real problems with them and the one I did they Autozone gave me a brand new one.
What do you recommend? If my Optima fails I need a sealed battery, so when I dump my Jeep on its side I don't have to worry about the battery.
Its also good info for the guy who started this thread.

I might be confusing my reds, blues & yellows (blue = marine; red = cranking; yellow = crank/deep compromise etc deep?)
But winches (like BIG audio) are a problem - they are often used to a great DOD (depth of discharge) but also have a very high current - so which battery type do you chose? Cranking is clear - high current but short discharge.
Locally I'd probably choose Deka (based on my batt shop's recommendations) though I'd be very keen to try a Yuasa UXH UPS battery - the UXH100-12 (100AH 12V) is ~$500 which is $50 less than the Optima yellow RRP (~70AH). (It's also $150 less then the 38AH UXH38-12 I am currently using as a cranker!)
I used to think highly of Odyssey (as I once did Optima) though my shop also reckoned no (like Optima, too many returns).
Stateside many recommended Kinetic, though I recently read good things about one of the "Platinums".
Alas whether this is good info is questionable. We know nothing of the OP's desires.
And too much info confuses may. (And some may be mere opinion...)
But yeah, other than maybe NOT addressing the OP's issue/s, I generally like extra info and POVs (but not deliberate scams etc!!).

i'm getting different information from each installation person I speak to. I would like to know what actually determines if I will need second alternator, or higher output, additional battery, capacitor or all of the forementioned. I have a 2000 blazer 4X4 with an alpine hu and three amps: 2 memphis sc16-sc2.120 for front(components 70 RMS) and rear door speaks (65 RMS) plus, JL Audio, JL J2 1000.1 for the sub (Kenwood KFC-XW 1225db).

Thanks in advance,

Rubbish.
Or rather, it's as much rubbish as saying "do not use petrol/gas or batteries" etc because they too blow things to pieces.
A battery is equivalent to millions of Farads.
Ever seen a battery blow up or an AGM go into thermal runaway?
I know of far more battery injuries than I do cap injuries.   
However, caps are usually a waste of money, their main use being to protect AGMs else remove lighting etc sags without the complications of another battery (even if that battery only costs $10).
But as a means of extending power... Like I said, a battery is millions of Farads.
