Having owned DeWalt 18 V cordless tools for about two years, I finally got around to reading the directions for the battery charger. It says that after a battery is charged, 1 hour later the charger begins a process of "leveling" to equalize the charge on the cells. It says this should be done to batteries after 10 discharge-recharge cycles.
I tend to stick a discharged battery in the charger and leave it overnight. So my batteries get "leveled" on each charge. Is this good or bad for them?
