I think you are talking about Optima batteries. Yea I've got one in my Minivan :) It's the main battery and has been working great for quite awile. 3 year free replacement. I have the Red top battery but all the young bucks say the yellow lasts longer. I didn't see much difference. http://www.optimabatteries.com/publish/optima/americas0/en/config/home.html
I'm adding a second one thats going to live in the rear part of the van. You can mount these upside down in the passenger seat if you so desire. No venting issues (they say) Real nice thing if you have a GM (side post) battery, It gives you that extra set of top posts to wire radios to in a separate set of circuits. I'm running a 4 guage to the rear of the van and using a expansion block to split it off to several fused circuits for other radios. Also fused at the battery.
