Charging an optima battery

Haven't watched the vid yet, but I have an OLD Optima that's been sitting around for 10+ years. I also have a new one I purchased w/in the last year to replace it, since I ASSumed the old one was nothing but scrap now.


The video is good. They recover a 20 year old Optima by using another battery as a storage cell. The trick requires a battery charger with a 10 amp setting. Trickle charger doesn't work and neither does the super blast type of charger.
