I'm not a big fan on running 2 batteries... a battery
is a storage device.... I run a single lead acid
production type battery WITH a alt(80a).... if it
isnt working then you need a better battery or a bigger
alt... if the car cant start in 5 seconds you should
fix the problem.... some of the guys are using the
added battery for weight and thats fine and dandy but
you could do the same thing with lead bars farther
back to do the same.... any ways, to each their own.
I have heard some bad things about the Optima batteries
in the last few years... at Chrysler we use to use
them as a production battery and changed due to a
high warranty on them
