Speaking of Optima...anybody know whether a Optima Red Top will fit properly under the hood of a Coupe GT (type 85)? My CGT is almost due for a battery and my local shop can get me blemished but new Optimas for $60. But I want to make sure it will fit. The computer at AutoZone doesn't list the Optima as fitting, but I don't trust their computer, it tried to tell me to put Bosch Platinum Plus4 plugs in my CGT. The Optima Red Top is a bit taller than the "standard" battery for my car (Group38?) and I want to make sure there won't be any battery terminal to hood contact...

That's pretty short, yes- but lead-acid batteries can die any of a
number of ways(sulfation and shorted cells are the #1/2 causes of
battery "death"; sulfation from undercharging), and if they're not
properly maintained, they won't last.

See my last paragraph for brand stuff....but most any battery should
be fine as long as you don't max out the Cold Cranking Amps; get only
enough CCA for what the vehicle recommendations are, because higher
CCA rated batteries use finer grids on the plates to maximize surface
area. Hence the plates break apart under vibration and charging more
easily. This warning does not apply to spiral-wound SLA's, which of
course use drastically different construction techniques.
I'm quite happy with my Optima thus far. Even after leaving the
interior light on for over 12 hours, the car started one morning in
December for work with no hint of trouble. Actually, I've done it
twice by accident. It also had no trouble starting the car in -25
degree weather with 10w30 oil in the engine at this year's winter
driving school(the after-run pump is another matter- it died the
usual death...)
I'd suggest going through the lead-acid battery
FAQ(http://uuhome.de/william.darden/) to evaluate your existing
battery before outright replacing it. Are levels OK? Are the plates
a consistent color between cells, and what color are they? What is
the state-of-charge(important: follow the directions re removing
surface charge, and note temperature corrections!) Etc.
Among other things, the site also contains a listing of who actually
makes what brand batteries, although it changes with frightening
speed, making buying by brand nearly impossible.
