This is true; but not necessarily conclusive. We checked the suspected chargers last year for Voltage and Current draw and concluded they were in specification. We checked them at the Troy district event where we were having the issues with leaky batteries. Using new chargers with new batteries this year is inconclusive because we changed two variables, the chargers and the batteries. We would have to be using the old chargers with new batteries in order to be conclusive.
Although not 100% conclusive, the sensible conclusion seems to point to the new batteries received at the Troy district event (may have been damaged in shipment or defective from the factory). What makes it less than 100% conclusive are other potentially unknown factors (charger may have been faulty in an intermittent way - happened when we were not testing?).
