But as far as I could see from my searches, there's no physical adapter out there to buy. There was a followup post several years later that indicated success still held. He stated he had to hold it in place with a bungie cord, but that it worked. I did find a thread on a forum called "Garage Journal" from 2013 where someone physically modified a 14.4v tool to be able to insert the 18v battery. The DCA1820 adapter is compatible with the following batteries only: 1.5 Ah, 2.0 Ah, 3.0 Ah, 4.0 Ah, and 5.0 Ah XR. This Adapter will not work with 20V/60V FLEXVOLT Batteries. I like using the DeWalt for certain "heavier" construction tasks since if I destroy it, I'm only losing a nearly 15+ year old tool rather than something more current. Very handy little adapter to mate a 12V Dewalt lithium ion battery to an older nicad 12, 14.4, or 18v tool. Do not use with premium DEWALT batteries in DC970 or DC759 tools. I had rebuilt the previous ones myself but they gave up the ghost a number of years ago and I already was using my Festool drivers. The 14v drill is a touch narrower so the latches are bottomed out against the adapter housing so there is no way to press them in any further to get clearance to remove the adapter.

Amazon also lists replacement batteries from more than one vendor that are supposed to be compatible with the DeWalt 14.4 devices. There appear to be some on "that auction site", but I didn't go look at them. I scored a couple of the 14.4v battery packs on the closeout table at Home Depot a few months ago.
