(for various reasons I needed to join a mismatched pair of 18v drill and battery, annoyed at how much fun it was)

      Be careful… IIRC, DeWalt batteries actually rely on circuitry in the tools, and it’s possible for an old tool to over-discharge them and reduce their capacity pretty drastically. Specifically, it seems the “low voltage cutoff” lives in the tool for DeWalt (and Makita and Milwaukee I think), while Ridgid, Ryobi, and B&D have it in the battery. The two former are for backwards compatibility, and I think the latter because god knows what stupid garbage tools they’ll throw at the line next (though my B&D sander is… fine).

        Yes, that’s the point. With an adapter the user must perform the low-volt-detection manually.

        @wjrii Thanks for the good information. I knew that PC NiCad tools had no communication to the battery, not sure about their newer LI ones. Regardless I find that the DW batt last so long on the PC tools that I always end up charging them when I think I should rather than when they actually need it. Rarely do they get down to 1 light, let alone full discharge As the PC tools die (which is taking a very long time, only 1 of 9 so far) going with DW brushless which have even better batt life.
