Black and Decker Firestorm battery charger
So far this product has performed as advertised. I am extremely satisfied with the drill motors themselves and have purchased other tools utilizing the same 18 volt battery. So far, all 4 of the chargers that have come with these tools has failed and failed quickly. That is why I offer the caveat 'so far' (1 month of use)

Charge time depends on the (18v) battery
B&D Fast Chargers are great. But to avoid disappointment as expressed by some of the reviewers, it's important to note the following:
B&D 18v batteries come in (at least) 3 varieties: 1.2, 1.5, and 2.1 ampere/hours. The 1.2 comes with most tools and has 2 terminals. The 1.5 (comes with some kits) and 2.1 "Silver Extreme" (sold as a "high performance" accessory) have 3 terminals - the third terminal apparently detects over charging.
B&D chargers also come in (at least) 3 varieties:
1) "Dumb" chargers that supply a constant charge current/voltage, i.e., like the charger that comes with most B&D products that has the brick that plugs in the wall and a small piece that slips onto the battery; these have 2 terminals.
2) "Semi-intelligent" 2 stage chargers that supply a constant charge current/voltage for charging, but then drop to a "maintenance charge state". These also have 2 terminals.
3) "Intelligent" fast chargers that charge at a faster rate, can sense overcharging and modify charge current accordingly, and then drop to a "maintenance charge state" once the battery is charged. These chargers have 3 terminals.
The (dumb) charger that comes with most B&D products that has the brick that plugs in the wall and a small piece that slips onto the battery does charge ALL the 18v batteries in about 6 hours - BUT - the manual warns not to leave the battery on the charger or battery life will be diminished (no "maintenance charge state", just constant contiuous current).
Semi-intelligent chargers charge at twice the rate as the "dumb chargers", thereby charging ALL 18v batteries in about 3 hours. These are chargers that come with the 3 piece garden set, dual chargers that come with some combo kits, etc. You can leave the batteries on these chargers "indefinitly" according to B&D.
The "intelligent" fast chargers (single & dual) will charge the 2 terminal 1.2 A/H battery in about 3 hours (same as the semi-intelligent chargers) BUT will charge the 1.5 & 2.1 ampere/hour batteries (with 3 terminals) in about 90 minutes. And, you can also leave the batteries on the fast chargers "indefinitly" according to B&D.
Hope this helps
