A few months ago, I built a box to hold my battery chargers. I installed a 2 hour timer and when a battery would go dead, I’d pop it into the charger, crank the timer up to two hours and let it cook. Things seemed to work fine.
I did not remove the now fully charged battery, but would leave it there until I needed it at a later time. Here is the question: All the sudden, within two days, all three of my Dewalt batteries died! Flat out would not take a charge, the lite on the charger would start out slow and then start going very fast. I sent two of the batteries off to get rebuilt and then the third one quit.
It appears to me that leaving a fully charged battery in the charger without power may be causing these to quit.
