That does sound bad. My experience has been much more positive: The four
Optimas in my family's cars are all running fine after several years (I think
the oldest one, in my TR4, has five years on it, with stock charging system).
But, as they say, your mileage may vary.
My point was not that Optima batteries are super reliable (which is
debatable, apparently)... my point is that it's worth paying extra to get a
sealed battery that won't leak and burn a hole in your car. If my Optima had
died prematurely, I would have gone looking for a different SEALED battery.
Better dead than leaky, says I. :)

P.S. Randall has a good point about improving the charging system to reduce the
amount of battery acid bubbling out of a standard battery. BUT, they still
leak, even in modern cars with (presumably) improved charging systems. I
haven't checked my 2000 VW yet, but my '95 Honda (a dry California car) had
obvious corrosion issues under the battery - and nowhere else - as did my '86
VW, '81 Toyota, '71 VW, '70 BMW, '67 Volvo, '67 BMW, '65 VW, etc etc. Geez,
I've owned a lot of cars over the years...
