DeWalt DCB204-2
These 4 amp hour batteries are the nuts. I ran one hard the second day after they arrived, couldn't believe the run time I got out of it. Drilled 10 3/8 inch holes in 3/16 steel then just to see what was in these batteries I used the impact gun to tighten the nuts and bolts. Ran all ten like it was a fresh battery. That night stuck the same battery in the flash light when I went out to feed, takes about 30 to 45 minutes, light was burning bright when I got into the truck to go home.
ProsRun time Charge indicator light Charging speed On sale Price
ConsNothing so far with battery Retail price

Great Batteries
I bought these to compliment the two 1.5ah batteries I got with my drill set. These work fantastically in the 20v Max drills, and charge quickly enough when I'm using the 1.5ah batteries to keep switching them so I'm never without batteries. A great upgrade to those who only have the 1.5ah or 2.0ah batteries.

Excellent Service and Great Product
The items were backordered and when I ordered them they confirmed the backordered items via email and a telephone conversation. When the items came in they shipped the same day and I received them 2 days later via priority mail. Excellent customer service!
ProsCustomer service was outstanding and item is 4ah battery for longer run time even on the tough cutting jobs

Dewalt 20 volt batterys
The 20 volt 4.0 amp hour batteries are even better than the 3.0 amp batteries. The side grinder and the circular saw have considerably more use time than before. They don't seem to take any longer to charge, but they do run longer. Very satisfied.
ProsMore power, quick to recharge
ConsSensitive to very cold weather

Fantastic batteries at a great price
I have been waiting for these 4.0Ah batteries and these guys had them at a great price. There is definitely a torque advantage over the smaller 3.0Ah batteries and these have the latest tech, including the fuel gauge. Would highly recommend for anyone on the Dewalt 20V platform.
ProsPower, gauge, same size as 3.0Ah battery
