Battery being dead and you charging as you did will not charge battery back even close to full charge. You need to 4-6 amp charge (slower the better) battery back to full charge, which will be at least 8hrs. Let set for at least 2hrs so surface charge goes down and then load test it. Really only way to check it correctly.
