I use one yellow Optima, no alt, no problem. 440, 12.5:1, small Chrysler starter, two classes each day, use a Black & Decker smart charger.

Most optima problems can be traced back to the owner using the wrong charger.

never use a regular charger, If for some reason it goes dead you must use a smart charger with a AGM setting.
