Salmo-I'm sorry, but I can't because I haven't needed one in some time. I do, however, know that exide is one of the largest battery makers in the US. Interstate is as well. I have always run interstates without any trouble. I use the interstate gel cell in the race cars I wrench on. Not sure of the deep cycling abilities of the "six-pack" gel-cell but on dry land there is nothing superior. I would talk to the mfrs. rep for your favorite brand and see what they advise. The guy behind the counter only knows what customers tell him for the most part. The rep will have (hopefully) facts verified by scientific tests. Good luck.
