We charge and maintain 4 at our field with a solar charger at 14.4 volts
P.S. I will match any price you find on BatteryMinder chargers -- a free SureGuard also.

What is the best way to charge an Optima battery? The usual 12/2 amp lead acid charger, a battery tender at 750 miliamps, a Schulze 6-

You _MUST_ have a charger that never exceeds the max voltage rating of the Optima (15.1 Volts) or it can vent and then it is trash. Many chargers will do this, so do some research before buying.
I just checked (it was bugging me). The Optima max voltage is 15.6 V. Some chargers can hit 16 V, hence the warning.
