No Vinnie, I think the battery could still be a problem.

Measuring the off-load voltage is not a reliable indicator of a battery's state of charge. What happens to the voltage when the starter motor is drawing a huge current is a good indicator.

You have the additional problem of a 0.7 amp current flowing when MGR's data suggests it should be about 5% of that figure.

So, solve the current drain first then evaluate your battery's condition.
