Optima dual post battery?

I just ordered the 800cca dual post red top from optima. Is this a good one for running a winch off the second set of posts???

No, the winch should only be run off of the large posts. There's too much amp draw for the side terminals.

IMO, there are better batteries out there than Optimas. They used to be really good.

I agree, I go though an Optima every 1 1/2 - 2 years.
As long as they keep warrantying it, I don't mind changing them

I have had an XD8000 hooked up to side posts on my redtop for years. Winch wasn't used often, but never any problems. A few weeks ago I did some hard pulls, bogging the winch down. When I moved that winch from one Jeep to the other the + side terminal had melted a bit on the batt. Bottom line, put the winch cables on the top terminals on the batt. Batt still works fine, but it melted it trying to pull a tree out of the road, so I can imagine it would ruin a batt with any extended heavy pulling.

So if the winch is too much for the side posts... Can I put the winch on the top large posts and put the starting terminals on the side???

I think we need to make a sticky about Optima batteries and the user comments about them - the Cliff's Notes version:

They're overpriced, Poor quality, and highly overrated. The Side terminals may work for extras like lighting (within reason), mild stereo setups, and a great power source for that bunch of switches to run all those relays for the aux lights, OBA, headlight upgrades, etc...

If you want a good winch battery, read that link Lucdog posted. The Short version:

A good Heavy Duty lead-acid flooded battery rated for commercial or heavy farm use. For the best set-up, 2 batteries isolated until needed..

Oh, and good cables rated for the current, not the cheaper smaller-gauge wiring that you get with the winch.
