"do not fast charge (high amps) a discharged Optima"

I have been given the opposite advice by more tan one auto electrician, a flat Optima will not respond to a low amp charger, it needs a high amp charge to bring it up then it can be maintained by a self regulating charger.

My attempts to charge a flat Optima with a small charger have certainly not been succesful.
