Glad to hear you got it fixed.
As far as charging the optima goes, there is a recomended charger from Ctek

There are several different version from them, I have this one more for my dune buggy's battery made by Total power because its finicky.
I have used a wal-mart smart charger on my optima's for years with no problems.
