DeWalt 12V - 20V Li-Ion Battery Charger

I would express an unpopular opinion, and say this is actually an excellent charger for the right application, provided, of course, you don't get an outright defective unit. Yes, it is slow, probably the slowest dewalt charger out there, but I WANT that - there is no need to overstress your batteries with a "fast charger" unless you are in a pinch (which is usually a poor planning). Simple rules for battery longevity are: 1. Minimize number of charging cycles; 2. Let the battery fully cool before charging (no hot-swapping); 3. Charge with the slowest compatible charger. I'm still rocking 4ah batteries circa 2013 (12hrs old by now) which are almost as good as they were on day one. This charger charged all of my batteries: older and newer 12v, and 4 ah/5 ah/ 2ah slimpack 20v's, in total 8 different batteries without a hiccup. I do have a contractors grade fast charger but I never use unless I do find myself in a dire need one day.

I purchased my Dewalt hedger last month. I love it. It operates for long periods of time without having to recharge the battery. It is long & cuts more judges. I previously bought another brand & it didn't last a season
