To any Dewalt employees out there: Regarding the DCA1820 adapter: The following is what it states on the Dewalt website: "Do not use adapter with premium batteries (DCB200, DCB204, DCB204BT, DCB205) in 18V Compact drills DC970, DC759. Use with DCB201, DCB203, DCB203BT compact batteries." What puzzles me is that it appears that it will only work with Dewalt's 1.5 Ah and 2 Ah Compact Slide-on Li ion Batteries. I don't understand why it shouldn't work with the so-called "Premium" 3, 4 and 5 Ah Batteries. The interface is exactly the same on all the XR Slide-on Batteries. Is this a marketing thing or is there some physical reason why this restriction is stated? Cheers, Peter
