This exact battery is still in daily use TODAY over 13 years old!
Comment below if you have tried or plan on trying this.
Battery was starting to show its age. It was very sluggish at cranking the old V8. The battery was fully charge by a battery charger and left to sit for 36hrs before the testing began. After adding epsom salt/distilled water and charging then slightly discharging 3 times the battery works a lot better.
