The only adapter I have and considered is for using the newer M18 Lithium batteries on my older Milwaukee 18 volt tools originally used nicad batteries. Since they chose to change the way the two battery systems connected to tools, which sucked. Works great being able to use the older tools with the newer batteries. Not sure I would use batteries between "battery tool species" even if I had other brands.
Mixing battery species using adapters seems to work for me. For three years, I’ve been using dewalt 20v lithium on older (black) Craftsman C3 nicad tools with an adapter and no issues. I switched to dewalt tools and batteries when the 3rd set of C3 batteries died years back. At that time, a dewalt small tool set with two batteries was less than replacement C3 batteries.
The C3 tools are my workhorses; they won’t die. I am very careful with the dewalt stuff.
YMMV
