New here, and to our 97TJ. Looking at replacing the battery, got winch, stereo, ARB air. Any imput on the Optium Blue D34M with extra power studs, and bottom clamp hold down bracket. Will it fit? And is this the battery to do the job? Or a red or blue top Optima? Any advice would be very appricated. Thanks.
I have run a red top, a duralast from autozone and most recently on the last TJ die hard gold with I think 900cca. Had ARB's winch etc.. no issues with any of them. The optima is nice as it can be mounted however you need it. Got the diehard as I could drop in to any sears no matter where I was and get it replaced if need be.

those batts are great but unless you plan on doing all that stuff with the engine shut off it won't make a bit of difference as to what kind of performace you'll get. the reason for a battery in the vehicle is to start the motor, once that happens the alternator takes over and powers everything and charges the batt back up. if you want better performace for powering accessories upgrade your alternator and you will be a happy camper.

The D34M would fit fine but my recommendation since Optima was bought out by Johnson Controls and their quality took a huge nose-dive, I'd go instead with a Sears Diehard Platinum. Like the Optima, the Diehard Platinum is an AGM (absorbed glass matting) battery but that's where the similarity ends.
I used to be a huge Optima fan and my last three batteries were Optimas... two Yellow Tops and the last one being a D34M Blue Top. All three died prematurely and I'm one of many who have completely given up on Optima. They used to be great batteries but their previous superb quality is long-gone now... at least in my personal opinion.
It was about three months ago my Blue Top died and I replaced it with the Diehard Platinum 34/78-DT. The engine even spins faster than it ever did with the Optima. There is also a lot more battery per square inch and I could tell that the Diehard Platinum was significantly heavier... I could barely lift it into the Jeep, unlike the Optima I pulled out.
The below illustration is why the Optima is so much lighter, look at the open space in Optima's spiral wound cell design when compared to the very dense design of the Diehard Platinum (made for Sears by MIL-SPEC battery manufacturer Odyssey).
Optima used to be a great battery, I've given up on them.

You can also Check out the Exide Orbital series-- they have an 34 XCD -- AGM battery with 1100 CCA's with dual terminals ... I will most likely go with this one-- as my uncle is dealer for exide and I can get it alot Cheaper than the optima or the diehard..
x2 on the Odessey or Sears Platnium. I got the Sears version a while back and it's working great. The big thing for me was not having to worry about the battery leaking. Now that I work from home, I don't drive the Jeep all that much and even after sitting for a couple of days, it'll start up strong.

My wrangler had dual yellow-top Optima batteries for about four years. I went around and around with Optima to verify how they would warranty their batteries in a dual-battery configuration. I was told that only in parallel and without the use of a isolator, etc. Well, as luck would have it, when I purchased my batteries from a local stereo shop I had a hunch they might not have been brand new. They only looked slighly used but for a battery, who knows what kind of abuse they put it through. I did notice that another of their batteries was connected behind a display for driving lights. When I asked how long they last, I was told oh we just throw them on a charger when the lights go dim. Anyway, the first pair were less than six months old when they both went out and I had my receipt and called for replacement. Optima was right on top of it, and got me a pair of refurbished yellow tops delivered to a local store where I was able to bring in my dying batteries and swapped in my new batteries. Those lasted me for roughly four years in a somewhat abusive configuration. My Jeep has a warn 9500 winch, a H4 conversion kit with wiring direct from the battery for higher performance, a pair of off-road (110watt) KC hilites up front and four 55watt H1 bulbs mounted as rock lights under the Jeep. At times my Jeep has my 1000 watt RMA JL audio amp powering two 12" subs (when the weather is nice.) For the four years I had the two batteries worked great. What I'm not looking forward to now is the $400 to replace both batteries as one of them died six months ago, and the second one followed it within a few months after.
On a side note, it does appear as if Optima changed their warranty terms for their batteries (on or around 2/1/2009). Optima Battery Warranties
Anyone have a price on the comparable batteries mentioned earlier?
Yowsa! I think if I shop around I can find a yellow-top for $180 or so. But then their warranty is 3 years max. Hmm. Thanks for the price and model. I'll have to shop around for that model as well and see if I can shave a few bucks off the price.
