Not for Firestorm batteries

According to DeWalt, this charger doesn't work with Firestorm batteries. I can confirm that it doesn't work with either of my 9.6 volt Firestorm batteries.

Seems very temperature sensitive

I have found that on about an 80 degree day, charging will never start unless the battery and charger are put in a shady spot for quite a while. Has anyone else had that problem? Not good for many job sites. I will follow up with DeWalt in case it's a malfunction.

So far so good

I bought this over-priced Dewalt charger to charge my Black & Decker Firestorm 14.4v batteries, since all three of my Firestorm chargers failed after only a few months of use (one of them after 2 weeks (and can't seem to buy just the charger). Hopefully this one will hold up. The Dewalt charger is working like a champ for now. I would have given it 5 stars, but I'm a little angery at Black & Decker (who also makes Dewalt). So only 4 stars.
