While the quality of our batteries has always been excellent, the batteries we are producing today are the best we have ever made. Many of the "bad" batteries returned to us under warranty are just deeply-discharged and work fine, when properly-recharged. It's primarily a charger technology-related issue and not unique to Optima. In fact, some other AGM brands have dealt with it by simply voiding the warranty on their batteries, if they are found to be deeply-discharged. We didn't do that with our warranty, but we did create a YouTube video, which explains how to recover deeply-discharged batteries (I'm not allowed to post links).
We have enough of these "discharge-only" batteries, that we now sponsor the Chumpcar World Series and supply their teams with these batteries we now call adOptimas. We handed 100 of them just at Road America the other weekend.

I watched he video
I'll post up my results later
I hope it will work.......:drool5:
I have my last optima that I screwed up and left the fog lights on....:loser:
I did charge it when it happened but didn't try either method in the vid
it did have more than 12 volts but would not crank the engine :food-smiley-019:
It's worth a shot
Any way , I liked my optimas , just didn't want to spend $200 ( my first ones were $120 a piece)
