[Benzito]

Running a SPF with Roush 402, not that I think that is the culprit . . .

So the Optima red top that has worked like a clock suddenly and completely dies. I mean suddenly and completely as in there is no crank, no lights, no nothing. I swap it for the newish battery in my 1968 Mustang and the Cobra runs like normal. So I figure, let me see if the dead battery works in the other car and of course, it does without any hesitation. Swap back and we're back to dead again.

The battery is getting old (Feb 2007 stamp), but I've never run into the problem that it seems to have NO draw at all.

I can't just keep the batteries swapped b/c of the size (have to get another Optima or something smaller than standard).

Thoughts? Better alternatives than the Optima (I read an old thread about Odyssey, but I have to check around to see if any local places keep them in stock).

Thanks!

Mike
