Bests & Worsts Reviews from Amazon

These are the longest lasting of 20 Volt Dewalt line: Model - Capacity - Color - Size DCB 200 - 3.0 Ah - 20 Volt standard black - thick DCB 201 - 1.5 Ah - 20 Volt compact black - thin DCB 203 - 2.0 Ah - 20 Volt XR premium yellow - thin DCB 204 - 4.0 Ah - 20 Volt XR premium yellow - thick DCB 205 - 5.0 Ah - 20 Volt XR premium yellow - thick The thin ones are the same size and appx weight The thick ones are the same size and appx weight There have been major price variations on here. I have seen them sold on Amazon for as high as just under $200 for 2 and as low as $149 plus delivery which is the price as of the date of this review. I am sure they will drop some more. If you want the highest capacity available make sure you compare prices of the 204 and 205 then decide if the extra 1 Ah is worth it to you.
