We had zero failures in 6 months of testing using other chargers then after the first batch was released we had 3 failures within a week, one customer had 2 of them both customers were using a MRC 977 we then immediately purchased one and had we not been closely montoring the charge we would have destroyed several batteries as the charger seem to have a mind of it's own which would have lead to several battery failures. This is why we recommend against it.
