Review on ⚡ DEWALT DC9310 1-Hour Fast Charging Charger for 7.2V-18V Battery - Efficient Power Solutions by Mike Ken

I bought this charger to replace a broken Black and Decker. Before giving it to him I "set" all my Dewalt batteries, 3 out of 6 held a charge all night for the full 5 minutes, the other 3 held a charge for about 1 hour. 3 days. We fix electronics, and the drill works all day, screwing and loosening. After charging the batteries for 8 hours, they all last all day, some for over 3 years! Pretty good results on my batteries as the charger wasn't even available for my store. Once my bats only have a short load left I WILL buy one for the store although my original works fine (the older model doesn't have a customization feature).
